CHAPTER 1 Getting Started

This chapter introduces the AG-320 and prepares you to use the ZyXEL utility.

1.1 About Your AG-320

The AG-320 is an IEEE 802.11a/b/g compliant wireless LAN adapter. You can also use the ZyXEL utility to turn your AG-320 into an access point (AP). The ZyXEL utility is a tool that helps you configure your AG-320. See the appendix for detailed product specifications.

Figure 1 The AG-320

The following table describes the AG-320.

1.2 Application Overview

This section describes some network applications for the AG-320.

1.2.1 Station Mode

The AG-320 is in wireless station mode by default. When the AG-320 works as a wireless station (wireless client), you can either set the network type to Infrastructure and connect to an AP or use Ad-Hoc mode and connect to a peer computer (another wireless device in AdHoc mode).

To connect to a network via an access point (AP), set the AG-320 network type to Infrastructure using the Profile screen. Through the AP, you can access the Internet or the wired network behind the AP.

Figure 2 Application: Infrastructure

1.2.1.2 Ad-Hoc

To set up a small independent wireless workgroup without an AP, use Ad-Hoc.

Ad-Hoc does not require an AP or a wired network. Two or more wireless clients communicate directly to each other.

Figure 3 Application: Ad-Hoc

1.2.2 Access Point Mode

You can also set the AG-320 to access point mode. In access point mode, your AG-320 allows you to set up your wireless networks without using a dedicated AP. The following figure shows a network example.

Figure 4 Application: Access Point Mode

In the example, the AG-320 is installed on computer A and set to operate in access point mode. Computer A provides an Internet connection to the wireless LAN, so wireless stations B and C can access the Internet.

Note: With WZC, you cannot use the AG-320 as an access point.

1.2.3 Changing AG-320 Mode

To change between the modes, select either Station Mode or AP Mode in any ZyXEL utility screens.

Figure 5 ZyXEL Utility: Change Modes

Note: Wait for about five seconds for the ZyXEL utility to complete the mode change.

The current mode is indicated by the color of the check box.

1.3 AG-320 Hardware and Utility Installation

Follow the instructions in the Quick Start Guide to install the ZyXEL utility and make hardware connections.

1.3.1 ZyXEL Utility Icon

After you install and start the ZyXEL utility, and insert the AG-320, an icon for the ZyXEL utility appears in the system tray.

Note: The ZyXEL utility system tray icon displays only when the AG-320 is installed properly.

When you use the ZyXEL utility, it automatically disables WZC.

Figure 6 ZyXEL Utility: System Tray Icon

The color of the ZyXEL utility system tray icon indicates the status of the AG-320. Refer to the following table for details.

Table 3 ZyXEL Utility: System Tray Icon

COLOR	DESCRIPTION
Red	The AG-320 is operating in wireless station mode but is not connected to a wireless network.
Green	The AG-320 is operating in wireless station mode and connected to a wireless network.
Pale Blue	The AG-320 is operating in access point mode.

Configuration Methods

To configure your AG-320, use one of the following applications:

• Wireless Zero Configuration (WZC) (the Windows XP wireless configuration tool)
• ZyXEL Utility (required when you want to use the AG-320 as an access point)

1.3.2 Enabling WZC

Note: When you use the ZyXEL utility, it automatically disables WZC.

If you want to use WZC to configure the AG-320, you need to disable the ZyXEL utility by right-clicking the utility icon (Z) in the system tray and selecting Use Windows to configure my wireless network settings.

Figure 7 Enable WZC

Refer to the appendices for information on how to use WZC to manage the AG-320.

To re-activate the ZyXEL utility, double-click the (Z) icon on your desktop or click Start, (All) Programs, ZyXEL AG-320 Utility, ZyXEL AG-320 Utility GUI.

1.3.3 Accessing the ZyXEL Utility

Double-click on the ZyXEL wireless LAN utility icon in the system tray to open the ZyXEL utility. The ZyXEL utility screens are similar in all Microsoft Windows versions. Screens for Windows XP are shown in this User's Guide.

Note: Click the icon (located in the top right corner) to display the online help window.

CHAPTER 2 Tutorial

The following sections show you how to join a wireless network using the ZyXEL utility, as in the following diagrams. The wireless client is labeled C and the access point is labeled AP.

Figure 8 Infrastructure Network

There are three ways to connect the wireless client (the AG-320 in station mode) to a network.

• Configure nothing and leave the wireless client to automatically scan for and connect to any available network that has no wireless security configured.
• Manually connect to a network (see Section 2.1 on page 29).
• Configure a profile to have the wireless client automatically connect to a specific network or peer computer (see Section 2.2 on page 32).

This chapter also includes a simple example of how to configure the AG-320 as an AP using the ZyXEL utility. See Section 2.3 on page 34 for more information.

2.1 Connecting to a Wireless LAN

This example illustrates how to manually connect your wireless client to an access point (AP) which is configured for WPA-PSK security and connected to the Internet. Before you connect to the access point, you must know its Service Set IDentity (SSID) and WPA-PSK pre-shared key. In this example, the SSID is "SSID_Example3" and the pre-shared key is "ThisismyWPA-PSKpre-sharedkey" in the AP.

After you install the ZyXEL utility and then insert the wireless client, follow the steps below to connect to a network using the Site Survey screen.

1 Open the ZyXEL utility. When the OTIST screen displays, click No. For information on the OTIST function, see Section 3.3 on page 41.

Figure 9 ZyXEL Utility: The OTIST Screen.

2 Click the Site Survey tab to open the screen as shown next.

Figure 10 ZyXEL Utility: Site Survey

3 The wireless client automatically searches for available wireless networks. Click Scan if you want to search again. If no entry displays in the Available Network List, that means there is no wireless network available within range. Make sure the AP or peer computer is turned on, or move the wireless client closer to the AP or peer computer. See Table 7 on page 48 for detailed field descriptions.
4 To connect to an AP or peer computer, either click an entry in the list and then click Connect or double-click an entry (with a SSID of SSID_Example3, in this example).
5 When you try to connect to an AP with security configured, a window will pop up prompting you to specify the security settings. Enter the pre-shared key and leave the encryption type at the default setting.

2.2 Creating and Using a Profile

A profile lets you automatically connect to the same wireless network every time you use the ZyXEL utility. You can also configure different profiles for different networks, for example if you connect a notebook computer to wireless networks at home and at work.

This example illustrates how to set up a profile and connect the wireless client to an access point configured for WPA-PSK security. In this example, the SSID is "SSID_Example3" and the pre-shared key is "ThisismyWPA-PSKpre-sharedkey" in the AP. You have chosen the profile name "PN_Example3".

1 Open the ZyXEL utility and click the Profile tab to open the screen as shown. Click Add to configure a new profile.

Figure 14 ZyXEL Utility: Profile

2 The Add New Profile screen appears. The wireless client automatically searches for available wireless networks, which are displayed in the Scan Info box. You can also configure your profile for a wireless network that is not in the list.

Figure 15 ZyXEL Utility: Add New Profile

3 Give the profile a descriptive name (of up to 32 printable ASCII characters). Select Infrastructure and either manually enter or select the AP's SSID in the Scan Info table and click Select.
4 Choose the same encryption method as the AP to which you want to connect (In this example, WPA-PSK).

9 Make sure the selected AP in the active profile is connected to the Internet. Open your Internet browser, enter http://www.zyxel.com or the URL of any other web site in the address bar and press ENTER. If you are able to access the web site, your new profile is successfully configured.
10 If you cannot access the Internet, go back to the Profile screen. Select the profile you are using and click Edit. Check the details you entered previously. Also, refer to the Troubleshooting section of this User's Guide or contact your network administrator if necessary.

2.3 Configuring the AG-320 as an AP

In access point mode, your AG-320 allows you to set up your wireless network without using a dedicated AP. Refer to Section 1.2.3 on page 26 and Chapter 5 on page 63 for more information.

Note: With WZC, you cannot use the AG-320 as an access point.

After you install the ZyXEL utility and then insert the AG-320, follow the steps below to set up your AG-320 as an AP.

1 Select AP Mode in any utility screen and wait for five seconds. The screen changes and displays as next. Under Status, you can view the current settings on the AG-320. In the Association List, you can see if any wireless clients have connected to your AG-320.

Figure 20 ZyXEL Utility: AP: Link Info

2 If you want to change the SSID and enable wireless security for your AG-320, click the Configuration tab and refer to Section 5.3 on page 65 for detailed field descriptions.

Note: You can use only WEP when the AG-320 is in AP mode.

CHAPTER 3

Wireless LAN Network

This chapter provides background information on wireless LAN network.

3.1 Wireless LAN Overview

The following figure provides an example of a wireless network with an AP. See Figure 3 on page 25 for an Ad Hoc network example.

Figure 22 Example of a Wireless Network

The wireless network is the part in the blue circle. In this wireless network, devices A and B are called wireless clients. The wireless clients use the access point (AP) to interact with other devices (such as the printer) or with the Internet

Every wireless network must follow these basic guidelines.

• Every device in the same wireless network must use the same SSID.

The SSID is the name of the wireless network. It stands for Service Set IDentity.

• If two wireless networks overlap, they should use a different channel.

Like radio stations or television channels, each wireless network uses a specific channel, or frequency, to send and receive information.

• Every device in the same wireless network must use security compatible with the AP or peer computer.

Security stops unauthorized devices from using the wireless network. It can also protect the information that is sent in the wireless network.

3.2 Wireless LAN Security

Wireless LAN security is vital to your network to protect wireless communications.

Configure the wireless LAN security using the Configuration or the Profile Security Setting screen. If you do not enable any wireless security on your AG-320, the AG-320's wireless communications are accessible to any wireless networking device that is in the coverage area.

Note: You can use only WEP encryption if you set the AG-320 to Ad-hoc mode.

See the appendices for more detailed information about wireless security.

3.2.1 Hide SSID

Normally, the AG-320 in AP mode acts like a beacon and regularly broadcasts the SSID in the area. You can hide the SSID instead, in which case the AG-320 in AP mode does not broadcast the SSID. In addition, you should change the default SSID to something that is difficult to guess.

This type of security is fairly weak, however, because there are ways for unauthorized wireless devices to get the SSID. In addition, unauthorized wireless devices can still see the information that is sent in the wireless network.

3.2.2 MAC Address Filter

Every device that can use a wireless network has a unique identification number, called a MAC address. A MAC address is usually written using twelve hexadecimal characters; for example, 00A0C5000002 or 00:A0:C5:00:00:02. To get the MAC address for each device in the wireless network, see the device's User's Guide or other documentation.

You can use the MAC address filter to tell the AG-320 in AP mode which devices are allowed or not allowed to use the wireless network. If a device is allowed to use the wireless network, it still has to have the correct information (SSID, channel, and security). If a device is not allowed to use the wireless network, it does not matter if it has the correct information.

This type of security does not protect the information that is sent in the wireless network. Furthermore, there are ways for unauthorized wireless devices to get the MAC address of an authorized device. Then, they can use that MAC address to use the wireless network.

3.2.3 User Authentication and Encryption

You can make every user log in to the wireless network before they can use it. This is called user authentication. However, every wireless client in the wireless network has to support IEEE 802.1x to do this.

Wireless networks can use encryption to protect the information that is sent in the wireless network. Encryption is like a secret code. If you do not know the secret code, you cannot understand the message.

3.2.3.1 WEP

3.2.3.1.1 Data Encryption

WEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted between the AG-320 and the AP or other wireless stations to keep network communications private. Both the wireless stations and the access points must use the same WEP key for data encryption and decryption.

There are two ways to create WEP keys in your AG-320.

• Automatic WEP key generation based on a “password phrase” called a passphrase. The passphrase is case sensitive. You must use the same passphrase for all WLAN adapters with this feature in the same WLAN

For WLAN adapters without the passphrase feature, you can still take advantage of this feature by writing down the four automatically generated WEP keys from the Security Setting or the Configuration screen of the ZyXEL utility and entering them manually as the WEP keys in the other WLAN adapter(s).

• Enter the WEP keys manually.

Your AG-320 allows you to configure up to four 64-bit, 128-bit or 256-bit WEP keys and only one key is used as the default key at any one time.

3.2.3.1.2 Authentication Type

The IEEE 802.11a/b/g standard describes a simple authentication method between the wireless stations and AP. Three authentication types are defined: Auto, Open System and Shared Key.

• Open System mode is implemented for ease-of-use and when security is not an issue. The wireless station and the AP or peer computer do not share a secret key. Thus the wireless stations can associate with any AP or peer computer and listen to any transmitted data that is not encrypted.

• Shared Key mode involves a shared secret key to authenticate the wireless station to the AP or peer computer. This requires you to enable the wireless LAN security and use same settings on both the wireless station and the AP or peer computer.

• Auto authentication mode allows the AG-320 to switch between the open system and shared key modes automatically. Use the auto mode if you do not know the authentication mode of the other wireless stations.

3.2.3.2 IEEE 802.1x

The IEEE 802.1x standard outlines enhanced security methods for both the authentication of wireless stations and encryption key management. Authentication can be done using an external RADIUS server.

3.2.3.2.1 EAP Authentication

EAP (Extensible Authentication Protocol) is an authentication protocol that runs on top of the IEEE 802.1x transport mechanism in order to support multiple types of user authentication. By using EAP to interact with an EAP-compatible RADIUS server, an access point helps a wireless station and a RADIUS server perform authentication.

The type of authentication you use depends on the RADIUS server and an intermediary AP(s) that supports IEEE 802.1x. The AG-320 supports EAP-TLS and EAP-PEAP. Refer to Appendix D on page 93 for descriptions.

For EAP-TLS authentication type, you must first have a wired connection to the network and obtain the certificate(s) from a certificate authority (CA). A certificate (also called digital IDs) can be used to authenticate users and a CA issues certificates and guarantees the identity of each certificate owner.

3.2.3.3 WPA and WPA2

Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, authentication and key management than WPA.

Key differences between WPA(2) and WEP are improved data encryption and user authentication.

Both WPA and WPA2 improve data encryption by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC) and IEEE 802.1x. WPA and WPA2 use Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication code Protocol (CCMP) to offer stronger encryption than TKIP.

If both an AP and the wireless clients support WPA2 and you have an external RADIUS server, use WPA2 for stronger data encryption. If you don't have an external RADIUS server, you should use WPA2-PSK (WPA2-Pre-Shared Key) that only requires a single (identical) password entered into each access point, wireless gateway and wireless client. As long as the passwords match, a wireless client will be granted access to a WLAN.

If the AP or the wireless clients do not support WPA2, just use WPA or WPA-PSK depending on whether you have an external RADIUS server or not.

Select WEP only when the AP and/or wireless clients do not support WPA or WPA2. WEP is less secure than WPA or WPA2.

3.3 Introduction to OTIST

In a wireless network, the wireless clients must have the same SSID and security settings as the access point (AP) or wireless router (we will refer to both as “AP” here) in order to associate with it. Traditionally this meant that you had to configure the settings on the AP and then manually configure the exact same settings on each wireless client.

OTIST (One-Touch Intelligent Security Technology) allows you to transfer your AP's SSID and WEP or WPA-PSK security settings to wireless clients that support OTIST and are within transmission range. You can also choose to have OTIST generate a WPA-PSK key for you if you didn't configure one manually.

3.3.1 Enabling OTIST

You must enable OTIST on both the AP and wireless client before you start transferring settings.

We use the P-334U in this guide as the example AP. Screens may vary slightly for your ZyXEL devices.

Note: The AP and wireless client(s) MUST use the same Setup key.

3.3.1.1 AP

On the P-334U, you can enable OTIST using the OTIST button or the web configurator. If you use the OTIST button, the default (01234567) or previous saved (through the web configurator) Setup key is used to encrypt the settings that you want to transfer.

Hold in the OTIST button for about two seconds.

In the web configurator, go to the Wireless LAN main screen and then select OTIST. To change the Setup key, enter zero to eight printable characters. To have OTIST automatically generate a WPA-PSK key, select the Yes check box. If you manually configured a WEP key or a WPA-PSK key and you also selected this check box, then the key you manually configured is used.

3.3.1.2 Wireless Client

Start the ZyXEL utility and click the Adapter tab. Select the OTIST check box, enter the same Setup Key as your AP's and click Save.

3.3.2 Starting OTIST

Note: You must click Start in the AP OTIST web configurator screen and in the wireless client(s) Adapter screen all within three minutes (at the time of writing). You can start OTIST in the wireless clients and AP in any order but they must all be within range and have OTIST enabled.

1 In the AP, a web configurator screen pops up showing you the security settings to transfer. After reviewing the settings, click OK.

2 This screen appears while OTIST settings are being transferred. It closes when the transfer is complete.

• In the wireless client, you see this screen if it can't find an OTIST-enabled AP (with the same Setup key). Click OK to go back to the ZyXEL utility main screen.

• If there is more than one OTIST-enabled AP within range, you see a screen asking you to select one AP to get settings from.

3.3.3 Notes on OTIST

1 If you enabled OTIST in the wireless client, you see this screen each time you start the utility. Click Yes for it to search for an OTIST-enabled AP.

2 If an OTIST-enabled wireless client loses its wireless connection for more than ten seconds, it will search for an OTIST-enabled AP for up to one minute. (If you manually have the wireless client search for an OTIST-enabled AP, there is no timeout; click Cancel in the OTIST progress screen to stop the search.)
3 When the wireless client finds an OTIST-enabled AP, you must still click Start in the AP OTIST web configurator screen or hold in the OTIST button (for one or two seconds) for the AP to transfer settings.
4 If you change the SSID or the keys on the AP after using OTIST, you need to run OTIST again or enter them manually in the wireless client(s).
5 If you configure OTIST to generate a WPA-PSK key, this key changes each time you run OTIST. Therefore, if a new wireless client joins your wireless network, you need to run OTIST on the AP and ALL the wireless clients again.

APPENDIX D

Wireless Security

Types of EAP Authentication

This section discusses some popular authentication types: EAP-MD5, EAP-TLS, EAP-TTLS, PEAP and LEAP. Your wireless LAN device may not support all authentication types.

EAP (Extensible Authentication Protocol) is an authentication protocol that runs on top of the IEEE 802.1x transport mechanism in order to support multiple types of user authentication. By using EAP to interact with an EAP-compatible RADIUS server, an access point helps a wireless station and a RADIUS server perform authentication.

The type of authentication you use depends on the RADIUS server and an intermediary AP(s) that supports IEEE 802.1x.

For EAP-TLS authentication type, you must first have a wired connection to the network and obtain the certificate(s) from a certificate authority (CA). A certificate (also called digital IDs) can be used to authenticate users and a CA issues certificates and guarantees the identity of each certificate owner.

EAP-MD5 (Message-Digest Algorithm 5)

MD5 authentication is the simplest one-way authentication method. The authentication server sends a challenge to the wireless station. The wireless station 'proves' that it knows the password by encrypting the password with the challenge and sends back the information. Password is not sent in plain text.

However, MD5 authentication has some weaknesses. Since the authentication server needs to get the plaintext passwords, the passwords must be stored. Thus someone other than the authentication server may access the password file. In addition, it is possible to impersonate an authentication server as MD5 authentication method does not perform mutual authentication. Finally, MD5 authentication method does not support data encryption with dynamic session key. You must configure WEP encryption keys for data encryption.

EAP-TLS (Transport Layer Security)

With EAP-TLS, digital certifications are needed by both the server and the wireless stations for mutual authentication. The server presents a certificate to the client. After validating the identity of the server, the client sends a different certificate to the server. The exchange of certificates is done in the open before a secured tunnel is created. This makes user identity vulnerable to passive attacks. A digital certificate is an electronic ID card that authenticates the sender's identity. However, to implement EAP-TLS, you need a Certificate Authority (CA) to handle certificates, which imposes a management overhead.

EAP-TTLS (Tunneled Transport Layer Service)

EAP-TTLS is an extension of the EAP-TLS authentication that uses certificates for only the server-side authentications to establish a secure connection. Client authentication is then done by sending username and password through the secure connection, thus client identity is protected. For client authentication, EAP-TTLS supports EAP methods and legacy authentication methods such as PAP, CHAP, MS-CHAP and MS-CHAP v2.

PEAP (Protected EAP)

Like EAP-TTLS, server-side certificate authentication is used to establish a secure connection, then use simple username and password methods through the secured connection to authenticate the clients, thus hiding client identity. However, PEAP only supports EAP methods, such as EAP-MD5, EAP-MSCHAPv2 and EAP-GTC (EAP-Generic Token Card), for client authentication. EAP-GTC is implemented only by Cisco.

LEAP

LEAP (Lightweight Extensible Authentication Protocol) is a Cisco implementation of IEEE 802.1x.

Dynamic WEP Key Exchange

The AP maps a unique key that is generated with the RADIUS server. This key expires when the wireless connection times out, disconnects or reauthentication times out. A new WEP key is generated each time reauthentication is performed.

If this feature is enabled, it is not necessary to configure a default encryption key in the Wireless screen. You may still configure and store keys here, but they will not be used while Dynamic WEP is enabled.

Note: EAP-MD5 cannot be used with Dynamic WEP Key Exchange

For added security, certificate-based authentications (EAP-TLS, EAP-TTLS and PEAP) use dynamic keys for data encryption. They are often deployed in corporate environments, but for public deployment, a simple user name and password pair is more practical. The following table is a comparison of the features of authentication types.

Table 34 Comparison of EAP Authentication Types

	EAP-MD5	EAP-TLS	EAP-TTLS	PEAP	LEAP
Mutual Authentication	No	Yes	Yes	Yes	Yes
Certificate – Client	No	Yes	Optional	Optional	No
Certificate – Server	No	Yes	Yes	Yes	No
Dynamic Key Exchange	No	Yes	Yes	Yes	Yes
Credential Integrity	None	Strong	Strong	Strong	Moderate
Deployment Difficulty	Easy	Hard	Moderate	Moderate	Moderate
Client Identity Protection	No	No	Yes	Yes	No

WPA and WPA2

Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, authentication and key management than WPA.

Key differences between WPA(2) and WEP are improved data encryption and user authentication.

If both an AP and the wireless clients support WPA2 and you have an external RADIUS server, use WPA2 for stronger data encryption. If you don't have an external RADIUS server, you should use WPA2-PSK (WPA2-Pre-Shared Key) that only requires a single (identical) password entered into each access point, wireless gateway and wireless client. As long as the passwords match, a wireless client will be granted access to a WLAN.

If the AP or the wireless clients do not support WPA2, just use WPA or WPA-PSK depending on whether you have an external RADIUS server or not.

Select WEP only when the AP and/or wireless clients do not support WPA or WPA2. WEP is less secure than WPA or WPA2.

Encryption

Both WPA and WPA2 improve data encryption by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC) and IEEE 802.1x. WPA and WPA2 use Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication code Protocol (CCMP) to offer stronger encryption than TKIP.

TKIP uses 128-bit keys that are dynamically generated and distributed by the authentication server. AES (Advanced Encryption Standard) is a block cipher that uses a 256-bit mathematical algorithm called Rijndael. They both include a per-packet key mixing function, a Message Integrity Check (MIC) named Michael, an extended initialization vector (IV) with sequencing rules, and a re-keying mechanism.

WPA and WPA2 regularly change and rotate the encryption keys so that the same encryption key is never used twice.

The RADIUS server distributes a Pairwise Master Key (PMK) key to the AP that then sets up a key hierarchy and management system, using the PMK to dynamically generate unique data encryption keys to encrypt every data packet that is wirelessly communicated between the AP and the wireless stations. This all happens in the background automatically.

The Message Integrity Check (MIC) is designed to prevent an attacker from capturing data packets, altering them and resending them. The MIC provides a strong mathematical function in which the receiver and the transmitter each compute and then compare the MIC. If they do not match, it is assumed that the data has been tampered with and the packet is dropped.

By generating unique data encryption keys for every data packet and by creating an integrity checking mechanism (MIC), with TKIP and AES it is more difficult to decrypt data on a Wi-Fi network than WEP and difficult for an intruder to break into the network.

The encryption mechanisms used for WPA(2) and WPA(2)-PSK are the same. The only difference between the two is that WPA(2)-PSK uses a simple common password, instead of user-specific credentials. The common-password approach makes WPA(2)-PSK susceptible to brute-force password-guessing attacks but it's still an improvement over WEP as it employs a consistent, single, alphanumeric password to derive a PMK which is used to generate unique temporal encryption keys. This prevent all wireless devices sharing the same encryption keys. (a weakness of WEP)

User Authentication

WPA and WPA2 apply IEEE 802.1x and Extensible Authentication Protocol (EAP) to authenticate wireless stations using an external RADIUS database. WPA2 reduces the number of key exchange messages from six to four (CCMP 4-way handshake) and shortens the time required to connect to a network. Other WPA2 authentication features that are different from WPA include key caching and pre-authentication. These two features are optional and may not be supported in all wireless devices.

Key caching allows a wireless client to store the PMK it derived through a successful authentication with an AP. The wireless client uses the PMK when it tries to connect to the same AP and does not need to go with the authentication process again.

Pre-authentication enables fast roaming by allowing the wireless client (already connecting to an AP) to perform IEEE 802.1x authentication with another AP before connecting to it.

WPA(2)-PSK Application Example

A WPA(2)s-PSK application looks as follows.

1 First enter identical passwords into the AP and all wireless clients. The Pre-Shared Key (PSK) must consist of between 8 and 63 ASCII characters or 64 hexadecimal characters (including spaces and symbols).
2 The AP checks each client's password and (only) allows it to join the network if it matches its password.
3 The AP and wireless clients use the pre-shared key to generate a common PMK.
4 The AP and wireless clients use the TKIP or AES encryption process to encrypt data exchanged between them.

Figure 72 WPA-PSK Authentication

WPA(2) with RADIUS Application Example

You need the IP address of the RADIUS server, its port number (default is 1812), and the RADIUS shared secret. A WPA(2) application example with an external RADIUS server looks as follows. "A" is the RADIUS server. "DS" is the distribution system.

1 The AP passes the wireless client's authentication request to the RADIUS server.
2 The RADIUS server then checks the user's identification against its database and grants or denies network access accordingly.
3 The RADIUS server distributes a Pairwise Master Key (PMK) key to the AP that then sets up a key hierarchy and management system, using the pair-wise key to dynamically generate unique data encryption keys to encrypt every data packet that is wirelessly communicated between the AP and the wireless clients.
