On the Security of three Versions of the WAI Protocol in Chinese WLAN Implementation Plan

Qiang Tang

Abstract: In this paper we investigate the security properties of three versions of the WAI protocol in Chinese WLAN implementation plan. We first revisit the security analysis that has been done to the version 1 and 2. we show that the security proof given by Li, Moon, and Ma is incorrect and the alternative protocol EWAP of Zhang and Ma is insecure. We further analyse the third version of the WAI protocol and prove its security in the Canetti-Krawczyk model. In addition, we also provide some practical security analysis of this version.
