| Abstract: |
| In this paper, we study the authentication and key agreement protocol for multi-server environment. Through the analysis of the scheme of Andola et al, an improved authentication and key agreement protocol is proposed by using the elliptic curve cryptography and random number. Besides, the security of the improved scheme is proved by BAN logic and the informal security analysis. Experimental results show that the proposed protocol has better security and practicability. |
