摘要
路由协议的安全性是移动自组网络安全中最重要的一环,极易受到各种攻击。分析AODV路由协议存在的主要安全隐患,探讨现有安全路由方案的不足,提出一种新的基于椭圆曲线密码体制、自证明公钥、单向哈希链等技术的安全高效路由方案,同时完成会话密钥的交换。仿真结果表明,改进后的协议以较少的开销得到较高的安全性。
Mobile Ad hoc networks usually use Ad hoc On-demand Distance Vector(AODV) protocol for lower overhead, but vulnerable to attacks for the lack of security mechanism. A security enhancement scheme based on Elliptic Curve Cryptography(ECC), self-certified pubic key, one-way Hash-chain is proposed, it establishes the session key between source and destination. Experimental results show that the proposed protocol is secure and efficient.
