卫星网络安全路由研究

Research on secure routing algorithm in satellite networks

依据卫星网络特点,对卫星网络安全的关键技术进行深入的研究,提出一种安全路由协议,该协议采用静态配置与动态调整相结合的策略,在网络拓扑变化时自动对路由进行调整,并为协议增加了基于信誉度的安全机制,使之能够检测到网络中节点的恶意行为并迅速做出反应,实现对网络内部及外部攻击的防范。

The key technologies in satellite networks security were researched. A security routing algorithm was proposed. By static configuration combining together with dynamic adjustment, the algorithm realized dynamic routing. Based on the credence model, the security mechanism was added. When it found there was malicious behavior in the network, it would react actively. It effectively guaranteed the security of satellite networks and protectd the network from kinds of attacks.
