基于可生存性的Ad Hoc网络容侵策略

Survivability-supported Intrusion-tolerance Policy for Ad Hoc

针对AdHoc网络可生存性的威胁因素,采用基于本地群的安全复原策略,在邻节点管理机制和本地协同投票机制的基础上提出双层安全实施架构,建立群内移动节点之间安全基础上的群间的安全联动;并以AdHoc网络路由协议AODV的内部误用为例,说明安全策略的实施。

In order to enhance survivability of ad hoc networks, this paper uses local collaborative groups-based recovery poIicy .The key modules of the policy are neighborhood watching mechanism and local collaborative w）ting mechanism. And this paper provides the two-level-enforced implementation architecture. As a result of the limitation of network resource, the architecture is based on mobile agent structure. This security policy and implementation architecture effectively assure the survivability ,security and availability of ad hoc network.
