【摘要】 虽然现在研究AdHoc网络中安全的文章很多,但是很少有人考虑到匿名的问题。本文中,匿名性的定义更加严格,将匿名性细分为身份保密、位置保密和路由匿名三个部分。文章提出安全匿名按需路由协议(SADR,Secure Anonymous Routing)不但保证了路由安全形成和维护,数据安全传输,并且同时满足了匿名性各个方面的要求,特别是很容易被忽略的身份匿名性和强位置保密性,使得恶意节点无法获得合法节点的身份与位置信息,从而难于进行攻击。为了清晰准确的表达SADR协议的过程,引入了DFA(deterministic finite automaton)进行描述,并使用BAN逻辑推理规则进行了安全性证明。最后,对比仿真数据,分析了加入安全匿名机制后,给性能上带来的影响。更多还原

【Abstract】 Though many papers are about security in Ad Hoc now, few consider the anonymous problem. This paper defines the anonymity more strictly. It divides anonymity into three parts which are identity privacy, location privacy, routing anonymity. SADR (Secure Anonymous on Demand Routing) is proposed. It can ensure routing and transporting data securely and satisfy the various anonymity requirements, especially identity privacy and strong location privacy that are neglected easily. The vicious nodes can’t get the identity and location information of the legal nodes, so they are hard to originate attacking. To represent the SADR protocol well, DFA (deterministic finite automaton) is quoted. On the other side, BAN is used to analyse the protocol’s security. At last, comparing the simulated data, it shows the affect after guaranteeing security and anonymity.更多还原
