移动通信系统的端到端保密技术研究
摘要
移动通信系统的保密性对于军用和民用来说都是必须具备的基本
特性之一在高度机密的情况下更是如此但是在现有商用移动
通信系统包括 2G 和 3G 中都没有实现端到端保密通信
因此设计基于核心网的具有端到端保密通信功能的移动通信系统就
非常具有研究意义和现实意义
本文对移动通信系统中的端到端保密技术进行了探讨和研究其
主要内容和特点包括如下几个方面
1 介绍了国内外对端到端保密通信系统的研究现状分析了存
在的主要问题和难点提出了自己的解决思路
2 在分析了经典基于公钥技术的无线认证协议后提出了一个
基于公钥技术并包含身份认证功能的密钥协商协议然后探讨该协
议对设计目标的满足程度最后用 SVO 逻辑对它进行形式化分析
3 提出了端到端安全保密通信系统的框架设计了终端代理
认证关系群组密钥管理语音加密和数据加密方案
4 对移动通信系统进行合法侦听是一项很重要的需求针对端
到端保密的特点采用了基于密钥封装的侦听方案
5 设计了仿真系统对本文中的协议交互过程进行模拟分析和
总结试验结果提出改进计划

STUDY ON END-TO-END SECURITY TECHNOLOGIES
OF MUNICATION SYSTEM
Abstract
Security is a basic feature of munication system for
military or civil use, especially in top-secret scenarios. Unfortunately, all
mercial munication systems nowadays (including 2G,
and 3G) don’t provide end-to-end security; therefore, it’s significant
to research on the end-to-end security munication system
based on work from theoretical or practical perspective.
This thesis discusses several end-to-end security technologies for
munication system. The main contents and characteristics are
as the following:
1. Introduces the current work on end-to-end security mobile
communication system of domestic or abroad scholars, analyses the main
problems and presents my own solutions.
2. Based on public-key cryptography, this thesis presents an
authentication and key agreement protocol for end-to-end security mobile
communication systems. During the design process the limitations of
munication systems are considered. Then the formalized
security proof of the protocol using the SVO authentication logic, and the
4
qualitative analysis about plexity are given. Results
show that the proposed protocol is secure and effective.
3. Presents the framework of end-to-end security mobile
communication system which includes mobile equipment, agent,
authentication
