Comparison TTLS and PEAP Comparison by Matthew Gast

Broadly speaking, the history of 802.11 security is an attempt to address two major problems. The first problem is that the protocols used to authenticate network users were not strong, so unauthorized users could easily access network resources. Second, the Wired Equivalent Privacy (WEP) system proved insufficient for a number of wellpublicized reasons. Our white paper “What’s Wrong With WEP?” discusses these in detail. In response to user concerns about weak security, the industry began developing a series of stronger protocols for use with wireless LANs. The key standard is IEEE 802.1X, which provides both stronger authentication and a mechanism for deriving and distributing stronger keys to bolster WEP.
