Proof of the Authentication Property of Secure WLAN Authentication Scheme (SWAS) using Protocol Composition Logic (PCL)

Authentication is one of the essential tools available for security in WLANs. Access control authentication mechanisms provides entity authentication, access into the network and key evolving for data frames protection. Secure WLAN Authentication Scheme (SWAS) is one such access control authentication mechanism. It provides entity authentication along with per frame authentication. All the participating entities in the scheme i.e. STA, AP and AS authenticate each other. The scheme makes use of cryptographic measure like delegation, key management, encryption and MIC for securing the scheme. The security properties of the scheme need to be validated for effectiveness. In this paper, a formal tool i.e. Protocol Composition Logic (PCL) is used for proving the authentication property of the scheme. General Terms Networks, Security, WLAN
