中文摘要： WSN节点因通常部署在无人值守、条件恶劣的环境导致节点易失效易捕获，且具有通信能力、电源能量、计算速度和存储空间有限和网络拓扑多变等特点，传统安全机制很难完全保证WSN的安全和可靠性。本课题拟提出一种基于节点行为和身份的无可信第三方的概率认证协议，并证明其有效性、可靠性和安全性。即研究基于贝叶斯理论和半环代数理论结合数据挖掘技术的WSN信任管理，建立与节点行为多种属性相关的的数学模型；研究依据节点信任度结合统计学原理识别异常节点方法；研究基于节点身份的密钥协商以及非异常节点间基于共享密钥的概率随机认证协议；研究认证协议的形式化建模、证明与检测技术保证其可信性；研究相关安全算法、协议软件及实验平台以验证其安全可靠性。目的是通过高效率的安全概率认证建立高容侵容错具有自治愈的WSN环境，为WSN的应用提供保障，进一步推动国内WSN的研究与发展。

英文摘要： It is easy to fail and be captured for nodes in WSN because of usually being deployed in the enviornment of unattended and severe condition. The nodes with variable network topology have limitation of communication capacity, power energy, commputing speed, memory space , and enable traditional security mechanisms not to be safe and reliable for WSN. This proposal will present a probability authentication protocol without a trusted third party based on node behavior and node identity, and validate it to be effective, reliable and safe. That is, it will investigate WSN trust management combining data mining technique based on Bayesian theory and semi-ring algebra theory, establish a mathematical model associated with many attributes of node behavior, study a detecting method for abnormal nodes based on node trust level and statistical principles, explore key agreements based on node identity and probability random authentication protocol based on the shared key between non-abnormal nodes, investigate formal modeling method for authentication protocol, validating and detecting techniques for guaranteeing its credibility, and relative safety algorithm, protocol software and experimental platform to verify its safety and reliability. The aim of this proposal is to construct self-healing enviornment with high intrusio
