基于SIP的IMS安全分析研究

SIP-based IMS Security Analysis and Research

文中详细分析了SIP协议的常见漏洞和IMS的安全机制,并以此为基础分析研究了在IMS中应用SIP协议的漏洞实施攻击的可行性。从分析结果可以看出,IMS的安全机制能够拒绝除了DOS攻击之外的所有的基于SIP漏洞的攻击。最后对DOS攻击进行了仿真验证。

This paper, in the light of the familiar loopholes in SIP protocol and the security mechanism in IMS, analyzes the feasibility of attack by using the leak of SIP in IMS. The result shows that the security mechanism of IMS can resist all the attacks but the DoS attack. Finally, this paper describes a simulation of the DOS attack.
