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。 The security of routing protocols is the most important part of mobile ad-hoc network security and is vulnerable to all kinds of attacks. This paper analyzes the main security risks of AODV routing protocols, discusses the shortages of existing security routing schemes, and proposes a new secure and efficient routing scheme based on elliptic curve cryptosystem, self-certified public key and one-way hash chain, etc. Session key exchange. Simulation results show that the improved protocol achieves higher security with less overhead.
