Research on secure authentication based on session initial protocol
一种基于SIP安全认证机制的研究

At present, most of the session initial protocol (SIP) authentication schemes only provide client-to-server authentication. And HTTP digest authentication is one of them. The weakness of this scheme in server spoofing and password guessing attacks was analyzed, and a more secure strategy was proposed which avoided these shortcomings. The experimental result illustrates that this proposed algorithm is effective.
