Appendix D Wireless LANs Types of RADIUS Messages The following types of RADIUS messages are exchanged between the access point and the RADIUS server for user authentication: • Access-Request Sent by an access point requesting authentication. • Access-Reject Sent by a RADIUS server rejecting access. • Access-Accept Sent by a RADIUS server allowing access. • Access-Challenge Sent by a RADIUS server requesting more information in order to allow access. The access point sends a proper response from the user and then sends another Access-Request message. The following types of RADIUS messages are exchanged between the access point and the RADIUS server for user accounting: • Accounting-Request Sent by the access point requesting accounting. • Accounting-Response Sent by the RADIUS server to indicate that it has started or stopped accounting. In order to ensure network security, the access point and the RADIUS server use a shared secret key, which is a password, they both know. The key is not sent over the network. In addition to the shared key, password information exchanged is also encrypted to protect the network from unauthorized access. Types of Authentication This appendix discusses some popular authentication types: EAP-MD5, EAP-TLS, EAP-TTLS, PEAP and LEAP. The type of authentication you use depends on the RADIUS server or the AP. Consult your network administrator for more information. 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. WAP3205 User's Guide 173
