一种改进的高效鲁棒的3GPP AKA协议

针对3G鉴权与密钥协商协议（3GPP AKA）中存在的安全缺陷,结合攻击者可能发起的攻击提出了一种可以防止重定向攻击,利用存在安全漏洞的网络发起的主动攻击,SQN同步缺陷和用户身份信息泄露的改进协议（ER AKA,Efficient and Robust Authentication and Key Agreement）,并对其安全性和效率进行了分析,分析表明通过该协议可以以较少的存储资源和计算资源为代价有效的解决上述安全性问题并减少3G系统中安全性处理的信令交互次数。

An Improved Highly-efficient and Robust 3GPP AKA Protocol

For the security flaws in 3G authentication and key agreement(3GPP AKA) protocol,an efficient and robust authentication and key agreement(ER AKA) protocol is proposed,thus to prevent the redirection attack,and the active attack based on the corrupted network,the defect of SQN synchronization and the leakage of users' identity information.Then the safety and efficiency of ER AKA is analyzed,and the analysis shows that ER AKA could solve the security problems at the cost of fairly few storage resource and com...
