| 摘 要： | 针对3G及4G网络发展中IMS系统的广泛应用及其AKA认证协议安全强度的不足，在分析CPK及IMSAKA认证机制的基础上，设计了一种基于CPK机制的IMS认证与密钥协商协议。经分析表明，该协议在提高强IMS智能终端的认证强度基础上，为引入额外的通信，并且扩展了IMS系统支持的认证机制。

| Abstract: | The safety of IMS system plays an important role in the evaluation of 3G and 4G network.The AKA protocol which is based on a long term shared key can not fulfill the requirements of wireless communication.On the basis of analyzing the(Authentication and Key Agreement) AKA and Combined Public Key(CPK) technology,a CPK-based authentication and key agreement protocol for IMS are proposed.The analysis show that the proposed protocol efficiently enhanced the security of IMS AKA protocol. |
