摘要
移动自组织网络缺乏可信第三方提供信任度量,节点可以依靠对其他节点特定行为进行主观判断以决定对其信任程度,而且行为特征还具有呈现与否的程度大小或者不知情的问题,为此,本文提出了一种基于直觉模糊理论的M ANET主观信任模型,并给出了信任的直觉模糊表述和实现方法,用于量化和评估节点的可信程度。仿真实验表明本模型是适合移动自组网安全的信任模型,能够有效地抵御网络攻击和信任模型攻击。
The absence of trust valuation presented by certain trusted third party in mobile ad hoc network(MANET) may result in that a node′s subjective trust in other nodes will only rely on their behavior,but the behavior may not present trust characteristics precisely.A subjective trust model based on intuitionistic fuzzy set theory(STMIFS) is proposed to quantify and evaluate the trust worthiness of nodes.Its intuitionistic fuzzy description and implementation are also given.The simulations show that STMIFS is suitable for MANET security and able to effectively defend against both ad hoc network attacks and trust model attacks.
