摘要/Abstract

摘要： LTE/LTE-A网络的设计为移动应用提供了较低的切换时延,但LTE标准中的切换过程仍存在一定的复杂性和安全缺陷。为了解决LTE标准和传统切换认证协议的缺陷,设计了一个基于盲签名的切换认证协议。在注册接入阶段通过盲签名建立用于切换过程的认证密钥,在切换过程中通过假名的可变换性和在特定条件下变为真名的可逆性来实现匿名性、不可跟踪性和条件隐私保护。理论分析和仿真结果表明,相较于LTE标准和其他切换认证协议,提出的协议在满足更多安全属性的同时,有更好的性能。

Abstract: LTE/LTE-A is designed to provide low handover latency for mobile applications,but there still exist some complexities and security vulnerabilities.To solve the vulnerabilities in the LTE standard and traditional handover authentication protocols,a new handover authentication protocol based on the blind signature was designed.In the registration phrase,the authentication keys used in the handover phrase are provided by the blind signature,and in the handover phrase,anonymity,untraceability and conditional privacy preserving are achieved by the exchange of the pseudonyms and the reversibility of the real identity.The theoretical analysis and simulation results show that the proposed protocol not only satisfies more security properties,but also has better performance compared with the LTE standard and other handover authentication protocols.
