WCDMA系统接入安全实现机制的研究

Study of access security mechanism of WCDMA

第三代移动通信系统的网络安全,特别是接入安全问题,是衡量移动网络能力的重要因素。通过WCDMA的安全体系及其接入安全实现机制,如:用户身份识别机制、本地鉴权和连接建立机制、接入链路数据的完整性保护、接入链路数据的私密性保护以及鉴权和密钥分配机制几个方面进行分析,以解决WCDMA中信息安全的保障问题。另外,还研究了WCDMA系统引入移动IP后对网络安全的影响。

The network security of the 3rd generation mobile communication system, especially access security, is an important factor of measuring mobile network capability. By analyzing the security architecture and the mechanism of access security of WCDMA, such as user identification, local authentication and connection establishment, access link data integrity, access link data confidentiality, authentication and key agreement, the author finds the solution of the information security in WCDMA, meanwhile the author studies the effect on network security when MIP is introduced to the WCDMA system.
