移动Ad Hoc网络中一种前向机密的匿名路由方案
Nanjing Hangkong Hangtian Daxue Xuebao/Journal of Nanjing University of Aeronautics and Astronautics（2010）
Abstract
传统移动Ad Hoc网络匿名路由方案主要基于公钥加密手段构建匿名路径.然而,一旦参与通信的节点私钥泄满,则匿名路径也会连带泄漏.针对这一问题,本文提出一种具有前向机密性的匿名路由(Forward secureanonymous routing,FSAR)方案.在FSAR中,节点通过基于伪名和双线性对的密钥协商机制动态协商会话密钥,并以此构建前向机密的洋葱路由完成匿名通信.理论分析和仿真实验表明,FSAR可有效解决传统匿名路由方案的前向机密隐患,同时在网络性能方面有更好的表现.
