基于聚合签名算法的DSR路由认证技术

分析了Ad Hoc网络中DSR按需路由发现原理及黑洞攻击原理,针对DSR路由协议面临的黑洞攻击问题,提出了一种基于JYH聚合签名算法的路由记录认证机制,新方案在DSR路由请求和路由应答消息中定义了路径证明属性,并设计了与之适应的输入签名算法和输出验证算法;最后,采用形式化逻辑SVO方法对该路由记录认证机制的安全性进行了分析。分析表明,提出的路由记录认证机制可以有效抵御针对DSR路由协议的黑洞攻击。

Novel DSR Routing Authentication Scheme Based on Aggregate Signature Algorithm

The principles of DSR route discovery and black hole attack are analyzed.To solve the black hole attacks faced by DSR routing protocol,we propose a novel route record authentication scheme based on aggregate signature algorithm. Specially, we define a path attestation in DSR routing request and answer message, and design an input signature algorithm and an output verification algorithm.Finally,we use SVO to analyze the security of our route record authentication scheme. Our research shows that the proposed route record authentication scheme can protect DSR from black hole attack.
