摘要
本文针对卫星广域网的特点,分析了该系统的数据安全问题。指出在卫星数据通信网中实施公开密钥算法进行密钥管理的必要性和可能性,提出了一种基本公开密钥算法和传统密钥算法相结合的保密通信实现方式,并给出了保密性分析。
According to SWAN communication network characteristic and requirement of security, we point out the possibility and necessity to key management using public key algorithms in VSAT networks. In this paper, a method to realize secure communication based on combination of public key algorithms and secret key algorithms is presented and its security is discussed according to various possible attacks.
