摘要
虽然标准的TETRA系统采用了一些安全方面的措施,但在系统内部信息仍然是以明文方式传输的,当遇上那些对信息传送的安全性非常敏感的用户必须进行端到端的加密时,标准的TETRA系统就不能满足安全的需求。文章对TETRA系统中端到端的加密中密钥管理进行了深入的分析和研究。
Although the standard TETRA system provides several security functions, the data are still transferred in clear text within the system. TETRA system is not able to meet the security requirements in the cases that involve sensitive transfer or end to end encryption requirement. The paper gives a in-depth analysis on the key management of end-toend encryption in TETRA system
