Page 55: Appendix B Types Of Eap Authentication
ZyAIR G-160 User’s Guide Appendix B Types of EAP Authentication This appendix discusses the five popular EAP authentication types: EAP-MD5, EAP-TLS, EAP-TTLS, PEAP and LEAP. The type of authentication you use depends on the RADIUS server. Consult your network administrator for more information. EAP-MD5 (Message-Digest Algorithm 5) MD5 authentication is the simplest one-way authentication method. - Page 56 ZyAIR G-160 User’s Guide LEAP LEAP (Lightweight Extensible Authentication Protocol) is a Cisco implementation of IEEE802.1x. 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.
