Research on Implementation of Identity Authentication Based on WAPI

Security of wireless local area network (WLAN) is a research hotspot at all times. Although many researches concerning security standards, principles and algorithms have been published, the implementation solution is seldom focused on. This paper studies the architecture of WLAN security authentication based on WLAN authentication and privacy infrastructure (WAPI) and presents a software solution to the authentication server. The P-V operations primitive is applied to construct an optimized multithread scheduling model to authentication services. The certificate authentication algorithm is designed based on OpenSSL encryption algorithms library. A prototype is presented to confirm the feasibility and effectiveness of the solution.
