摘要: In a single server environment, one is responsible for providing services to all the authorized remote users. However, problem arises if user wishes access several network services. To overcome this weakness, various multi-server authentication schemes have been proposed. 2012, Taygi et al. [1] proposed scheme environment. But it found that their insecure against impersonation attack, masquerading collaboration attack between valid and server, smart card stolen password guessing change attack. Then we propose an improved can possible attacks also provides better computational cost as well communication than related published earlier.
