3G移动通信系统中的个人信息保护解决方案

摘要

There are serious information leakage problem in wireless mobile communication,such as mobile terminal identity identification, location infor-mation, etc, since personal data protection in the current communication system is insufficient. This paper analyzes the domestic widespread used 3G wireless communication system at present, points out the existing of information leakage risk in the system, and gives the corresponding solutions. The new scheme can effectively protect the personal informa-tion of mobile terminal, preventing various kinds of attacks caused by information leakage. In addition, this paper also proposes solving strategy to tackle this kind of problem, and provides support for the subsequent protocol design of communication system.%当前通信系统对移动终端的身份标识、位置信息等个人信息保护不足，存在严重的信息泄露问题。分析了目前国内大范围使用的3G移动通信系统，指出了系统中存在的信息泄露风险，并给出了相应的解决方案。新方案可以有效保护移动终端的个人信息，防范由于信息泄露所引起的各类攻击。此外，还提出了应对该类问题的通用解决策略，为后续无线通信系统的协议设计提供支持。
