| 摘 要： | 拒绝服务攻击是AdHoc网络安全领域中的难题,本文提出一种新型的基于Agent的安全路由协议,Agent可根据其邻节点的可信度定期更新以适应AdHoc分布式路由计算环境,有效提高网络的可信性,降低网络安全计算的复杂度;根据拒绝服务攻击的特征抽取出Agent安全规则与检测算法.采用NS2网络模拟器的仿真结果表明,该方法能有效的检测出拒绝服务攻击并进行及时响应,使网络性能迅速恢复正常.

| Abstract: | Denial-of-Service(DoS) attacks are the main puzzles in the security of Ad Hoc network.A novel agent-based security routing protocol scheme was proposed to block DoS attacks.Agent can update itself at some interval by the trustworthiness of the neighbor nodes to fit the Ad Hoc distributed routing computing environment.It can efficiently improve trustworthiness and decrease computing complexity.Agent security specifications were extracted by the feature of the attacks.NS2 simulator is expanded to validate the security routing protocol.Simulation results show that agent-based security scheme is highly effective to detect and block DoS attacks. |
