A Research on the Security of OSA/Parlay Authentication Interface Yang Xun1 Wan Xiao-Yu1 Huang Yong2 Fan Zi-Fu1 (1. Next Generation Network Application Technology Institute of CQUPT, Chongqing， China 400065 2. ChongQing PuTian Communication Equipment Co.,Ltd, Chongqing，China 400039） Abstract ：In this paper, first, the OSA/Parlay framework based on the TSM architecture is discussed and the security of the authentication in the framework is analyzed. Then, a new TSM formal security model which combined the advantages of the two current TSM models is presented. Finally, by tracing analyses with CoProVe, the security flaws of the TSM protocol are detected, and the corresponding solutions for the flaws are brought up.
