[. . . ] For WPA, WPA2, WPA-PSK and WPA2-PSK authentication mode, the encryption type supports both TKIP and AES. None ­ No encryption is used. ­ 24 ­ CHAPTER 3 | Windows 2000/XP Configuration Wireless Utility Configuration WEP ­ Enables the Wireless USB Adapter to use WEP shared keys. If enabled, you must configure at least one key. Wired Equivalent Privacy (WEP) provides a basic level of security, preventing unauthorized access to the network and encrypting data transmitted between wireless clients. WEP uses static shared keys (fixed-length hexadecimal or alphanumeric strings) that are manually distributed to all clients that want to use the network. TKIP ­ Use Temporal Key Integrity Protocol (TKIP) keys for encryption. WPA specifies TKIP as the data encryption method to replace WEP. TKIP avoids the problems of WEP static keys by dynamically changing data encryption keys. AES ­ Use Advanced Encryption Standard (AES) keys for encryption. WPA2 uses AES Counter-Mode encryption with Cipher Block Chaining Message Authentication Code (CBC-MAC) for message integrity. The AES Counter-Mode/CBCMAC Protocol (AESCCMP) provides extremely robust data confidentiality using a 128bit key. Use of AES-CCMP encryption is specified as a standard requirement for WPA2. Before implementing WPA2 in the network, be sure client devices are upgraded to WPA2-compliant hardware. 802. 1X -- Use IEEE 802. 1X (802. 1X) for user authentication and distributing dynamically generated encryption keys. IEEE 802. 1X is a standard framework for network access control that uses a RADIUS server on the local network for user authentication. The 802. 1X standard uses the Extensible Authentication Protocol (EAP) to pass user credentials (either digital certificates, usernames and passwords, or other) from the client to the RADIUS server. Figure 17: Profile - 802. 1X Configuration EAP Method (LEAP) ­ The Lightweight Extensible Authentication Protocol (LEAP) is an EAP authentication type used primarily in Cisco Aironet WLANs. It encrypts data transmissions using dynamically generated WEP keys, and supports mutual authentication. When LEAP is select, input LEAP identity, password, domain name, and select encryption type. Check the Show Password box to display password characters as you type instead of asterisks. Identity / Password ­ Configures the identity an password for authentication. Domain Name ­ Enable the wireless configuration utility to check the end of domain name. If defects are found, the connection is dropped. ­ 25 ­ CHAPTER 3 | Windows 2000/XP Configuration Wireless Utility Configuration WMM Wi-Fi Multimedia (WMM), also known as Wireless Multimedia Extensions (WME), is a Wi-Fi Alliance interoperability certification. It provides basic Quality of Service (QoS) features for IEEE 802. 11 wireless networks. Figure 18: WMM The displayed items on this page can be described as follows: WMM Enable -- Enable WMM function. WMM - Power Save Enable ­ Enable the power save mode. Best Effort ­ Normal priority, medium delay and throughput. Data from applications or devices that lack QoS capabilities.
