摘　　要：针对3GPP最新发布的LTE/SAE Release 8标准,研究了LTE/SAE安全体系架构及在无线协议栈中的实现机制。首先概述了LTE/SAE的安全功能,然后详细研究了LTE/SAE的安全体系架构与安全机制,指出了新机制中可能仍存在的安全缺陷,最后结合LTE无线协议栈的研发工作,设计并实现了LTE/SAE接入层安全机制。该方案实现简单,对LTE/SAE系统安全具有重要作用。Based on the recently released LTE/SAE R8 standard by 3GPP,the security architecture of LTE/SAE and its realization mechanism in radio protocol stack are presented. Firstly, the security function of LTE/SAE is summarized, then the security architecture and mechanism of SAE/LTE are studied ,and some defects are pointed out. Finally ,in combination with the research work on LTE protocol stack, the security mechanism of access layer for LTE/SAE is designed and realized. This solution is simple and is important for security of LTE/SAE.
