无线Mesh网中基于推荐信任的身份认证方案

Identity Authentication Scheme Based on Recommendation Trust in Wireless Mesh Network

为了提高无线Mesh网络的安全性,提出基于推荐信任的身份认证方案.当目标节点要求加入网络时,源节点发出推荐请求,响应请求的推荐节点用推荐信任值评价目标节点的可信度.该方案将各推荐节点的推荐信任向量加权综合后量化,源节点可根据信任等级直观有效地判断一节点的可靠性,由此避免非可靠节点的加入,提高了网络的安全性.

To improve security of wireless mesh network, a scheme of identity authentication based on recommendation trust is put forward. When target node requests to join in the network, source node broadcasts recommendation request, recommendation nodes respond to the request and evaluate the reliability of target node by value of recommendation trust. The scheme integrated evaluate the recommendation trust of recommendation nodes based on weighting factor. Source node can judge the reliability of node visually and effectively by trust grade, which can avoid unreliable node and impove the security of WMN.
