CDMA系统空中接口安全机制分析

Analysis of Security in CDMA System Air-interface

由于使用无线传输和网络的开放性,移动通信面临着很多安全威胁。该文重点研究CDMA系统空中接口的安全机制,详细分析了针对主动攻击的鉴权机制的原理和过程,以及被动攻击的加密机制,其中重点介绍了一种数据加密技术——混合密码体制。

Due to the use of wireless transmission and networks open, mobile communications is faced with a lot of security threats. This article focuses on security mechanism in CDMA air-interface system. For a detailed analysis, it studies principles and the process of the authentication mechanisms as the initiative to attack, as well as passive attacks on the encryption mechanism, which focuses on a data encryption technologies-hybrid cryptosystem.
