摘要
无线传感器网络环境下的信任模型作为密码技术的有效补充,在抵抗内部攻击、识别故障节点等方面发挥着重要作用,可应用于安全路由、安全数据融合等,用以提高系统的安全性、可靠性和公平性;分析了无线传感器网络环境下信任模型的特性,详细介绍了信任模型的评价指标;选取4种典型的信任模型进行评述,分析其优势和不足,并根据各项评价指标进行比较;最后指出目前研究中存在的问题,并展望了进行后续研究的切入点。
In Wireless Sensor Network（WSNS） environment,as an effective complement to cryptography technology,the trust model plays an important role in the resistance to internal attack,identify the faulty nodes,etc.And it can apply to secure routing,security data fusion,etc.,to improve system security,reliability and fairness.The characteristics of trust models for WSNS are analyzed;the evaluation indexes of trust models are described in detail.Four typical trust models are selected and reviewed;their advantages and weaknesses are discussed and compared based on the evaluation indexes.The current research problems are concluded and the entry points for further study are proposed.
