现代移动通信信息安全技术研究

Study on Information Security Technology in Modern Mobile Communication

随着移动通信和计算机技术迅猛发展,移动通信用户人数也在呈现爆发式的增长,移动通信产业市场潜力发展特别巨大,随之而来的人们对移动通信提出了更高的要求。回顾移动通信技术经历了由1G到4G的发展,通话和数字传输功能得到巨大的提高和完善,但是4G系统LTE/LTE-A网络的安全问题却经常被提出,本文就对LTE中的体系结构、访问机制、切换过程中的安全问题进行了研究。

With the rapid development of mobile communication and computer technology, the number of mobile users is increasing quickly, so the mobile communication industry has a huge potential market. Meanwhile, this brings higher requirements on the mobile communication. In the process of mobile communication system from 1G to 4G, voice and digital transmission function get great improvement. However, the security problem of LTE/LTE- A 4G has often been proposed. Therefore, this paper will mainly study the security problems of the architecture, access mechanism of LTE and those in the process of switching.
