3G移动网络的安全问题

第三代移动通信系统是工作在2 GHz频段的宽带移动通信系统,它与第二代移动通信系统的区别主要有:全球无隙漫游、支持高达2 MB/s的多媒体业务等,特别在Internet上提供更好更广的服务。而在这其中也会涉及到许多安全方面的隐患;因此就3C网络的安全问题作了简要陈述,同时给出了UMTS网络结构和3G的安全结构,并说明了3G安全中的重要技术及其存在的威胁。

Security in Third Generation Mobile Networks

The third Generation Mobile Telecommunication System is a kind of wideband mobile communication system, which works at 2 GHz. The major differences between 3G and 2G lie in that 3G supports global seamless roaming and multimedia business up to 2 MB/s , especially offering better and wider services on Internet. All of these also revolve many hidden security risks, so the issue on security in 3G is introduced. At the meantime, the UMTS network structure and 3G security architecture are presented and the major techniques and open threats are explained.
