摘　　要：研究了移动Ad hoc网络(MANET)的安全路由问题,分析了现有MANET入侵检测和安全路由策略的优缺点.针对MANET安全和路由问题的特殊性,提出并实现了基于ECC的MANET安全路由算法.算法吸收了表驱动路由和按需路由策略的优点,具有能耗低、延迟小、递交率高等显著特点.并且算法在路由过程中引入了ECC签名认证机制,通过路由过程中的签名认证,使得有害节点不能参与到路由中,保证了路由的安全性、信息的完整性和不可抵赖性.最后利用NS-2仿真器对算法的性能进行仿真分析,结果显示所提出的安全路由算法是高效的.The problem of secure routing for MANET （mobile ad hoe network） is studied. Analyzing the advantages and disadvantages of intrusion detection and secure muting policies, an ECC-based secure muting algorithm for MANET is presented and implemented according to the special secure routing requirements of the MANET. The algorithm has obviously the advantages of those of the on-demand and table driven muting policies sueh as low energy consumption, short delay and high delivery rate etc. The signature and authentication based on ECC are introduced in the process of routing to exclude the malicious nodes from joining the route, which can ensure the security of the route, the integrity of data and non-repudiation. The performance of the algorithm presented is analyzed with NS-2, and the simulative results show its high efficiency.
