移动通信环境下对称密钥分发安全机制

Security Schemes of Symmetric Key Distribution in Mobile Communication~

文章简述了移动通信环境的特点，并从机密性、完整性、鉴别性、防重放攻击等方面，分析了移动通信环境下对称密钥分发所面临的安全威胁，并有针对性地提出了多种的安全机制。经过系统验证，这些安全机制能够有效增强移动通信环境下对称密钥分发的安全性。

This paper briefly describes the characteristics of mobile communications system, and analyzes the security problem of symmetric key distribution in mobile communications, and proposes various security schemes of privacy, integrity, authentication and replay prevention. Experiment indicates that these schemes could enhance the security of symmetric key distribution in mobile communications.
