会话发起协议(SIP)是在3G移动的网络中使用的认证协议。2009年,Tsai提出了一个认证密钥协商方案作为SIP的增强。Yoon等人后来指出,Tsai的方案容易受到离线密码猜测攻击,Denning-S攻击和被盗验证者攻击,并且不支持完美前向保密(PFS)。Yoon等人进一步提出了一种新的PFS方案。在本文中,我们证明了Yoon等人的方案仍然容易受到被盗验证者攻击,也可能受到离线密码猜测攻击。针对这些问题提出了相应的对策。此外,我们提出了一种新的安全增强的SIP认证方案。我们的方案也保持了较低的计算复杂度。版权所有© 2011约翰威利父子有限公司.
The session initiation protocol (SIP) is an authentication protocol used in 3G mobile networks. In 2009, Tsai proposed an authenticated key agreement scheme as an enhancement to SIP. Yoon et al. later pointed out that the scheme of Tsai is vulnerable to off‐line password guessing attack, Denning–Sacco attack, and stolen‐verifier attack and does not support perfect forward secrecy (PFS). Yoon et al. further proposed a new scheme with PFS. In this paper, we show that the scheme of Yoon et al. is still vulnerable to stolen‐verifier attack and may also suffer from off‐line password guessing attack. We then propose several countermeasures for solving these problems. In addition, we propose a new security‐enhanced authentication scheme for SIP. Our scheme also maintains low computational complexity. Copyright © 2011 John Wiley & Sons, Ltd.
