摘　　要：首先提出了群推荐的概念,在此基础上,提出了一种新颖的动态的多跳无线网络安全信任模型.该模型克服了已有的多跳无线网络信任模型的若干局限性,通过对节点行为进行综合评估,为网络中节点之间的合作和安全决策提供更细致和精确的依据,并能动态反映信任关系的变化状况,为通信节点是否可信建立了一个较为明确的判断标准.该模型能够较好地抵抗恶意节点的欺骗行为,提高了节点的可信度,能有效解决多跳无线网络中的盲目信任问题.The concept of group recommendation （GR） is presented. Based on group recommendation, a novel dynamic trust model for multi-hop wireless network is proposed, which overcomes the disadvantages of trust models existed in current movable self-organized network. More precise trust judgment for the cooperation and communication between nodes can be provided through integrated evaluation on the node＇s behavior in model. Furthermore, the status change of trust relationship can be revealed, and the integrative trust criterion between the nodes can be established effectively. This new method can stand against the cheating behavior from hostile nodes preferably, which solves the problem of blind trust effectively during the authentication process in multi-hop wireless network.
