摘要
在移动Adhoc网络中,安全性是保证其可用性的一个重要方面。文章提出了一种针对按需路由协议的安全性改进方案,这种方案采用了对邻居节点的身份即时认证、对远端节点按需认证、匿名寻找路由、逐跳加密传输的机制,能够有效地阻止恶意节点对网络的窃听、篡改等攻击,确保网络路由信息的安全。
Security is an important aspect for assuring the availability of MANET. This paper proposes an improved scheme of the security for on-demand routing protocol. It uses instantaneous node identification on the neighbor nodes and on-demand identification on the remote nodes. It finds the route anonymously and employs H-by-H encryption transmission mechanism, thus can prevent nodes attacks from malicious nodes effectively and emsure the safety of routing information.
