摘要
3G移动通信系统中的接入安全技术是在2G安全基础上建立起来的,克服了GSM中的问题,增加了新的安全功能。虽然3G系统网络接入的安全协议较GSM系统有所改进,特别是增加了移动台对网络的鉴权,但安全协议并没有完全达到其设计目标,如何完善还需进一步探讨。
Access security technology in 3G mobile communication network is built on the basis of 2G system, which overcome the disadvantages in GSM and added new security features. However, although the 3G network access security system has improved in eomparision with the 2G security protocol, especially in the authentication of mobile station for network, the security protocol still has not achieved its design objective and needs further studies.
