改进型安全自组网按需距离向量路由协议研究

Study on Improved Secure Ad Hoc on-Demand Distance Vector Routing Protocol

提出了一种新的效能较高的具备安全鉴别功能的自组网按需距离向量路由协议ESAODV。该安全协议采用HORSEI认证机制,其签名和验证的计算速度比公钥算法快很多,它的安全性基于单向散列算法,且不需收发者之间的时间同步。理论分析和网络仿真结果表明,与最新因特网协议草案所提出的方案相比,安全协议ESAODV具有较好的性能和实用性。

This paper presents a new efficient secure Ad hoc on - demand distance vector routing protocol （ESAODV）. The pro- tocol takes the HORSEI for authentication, with higher signing and verifying speed than that of public key based authentication schemes. The security of the protocol relies on the one way hashing and needn1 time synchronization. Compared with the latest Intemet draft of SAODV, ESAODV is proved to be more efficient and practical through theoretical analysis and simulation.
