TD-LTE系统接入层安全性实现与测试

Realization and Test of Access Stratum Security in TD-LTE

可靠的高性能安全性算法是LTE高速数据传输的重要保障,接入层的安全性由PDCP子层来实现。介绍了在开发TD-LTE射频一致性测试仪的PDCP子层的过程中安全性流程的设计、加密和完整性保护算法的实现,然后采用规范描述语言(SDL)和树表描述语言(TTCN)的协仿真功能对PDCP层安全性流程设计和实现方法的正确性进行测试。测试表明该设计能实现接入层的安全性功能。

Reliable and efficient security algorithm is an important guarantee of high-speed data transmis-sion of LTE in the wireless access technology. Security of access stratum is realized by PDCP sub-layer. In the development process of PDCP of TD-LTE Radio Frequency Conformance Testing System, we designed a detailed security process and realized it with encryp-tion algorithm and integrity algorithm. This paper adopts SDL and TTCN to verify the design of security process of PDCP, and test shows that security func-tions can be realized by the design.
