摘要
Abstract
Through analyzing the Session Initiation Protocol(SIP) authentication mechanism, this paper describes the vulnerability and possible attacks, such as off-line password guessing attacks and Denning-Sacco attacks. Aiming at such security problems, an improved SIP authentication scheme based on Elliptic Curve Cryptography(ECC) is proposed. Security analysis demonstrates that the improved scheme can provide mutual authentication, share the session key, guarantee the validity of authentication, effectively resist against off-line password guessing attacks and Denning-Sacco attacks.关键词
