中文摘要： 无线传感器网络中机会主义路由技术的多个候选节点共同协作参与报文转发的特性与传感器节点资源有限的特点，使得现有的密钥管理和安全防护机制无法处理机会主义路由中存在的安全问题。本项目拟研究一套低耗高效的基于公钥密码算法的分布式邻近区域群组密钥管理机制以及在此基础上的安全机制：研究机会主义路由中逐跳一对多通信方式的安全模型，设计区域双线性对群组密钥的安全分发、认证、更新与撤销等协议；研究基于区域群组密钥的位置密钥指纹，在此基础上设计安全高效的分布式身份认证机制；最后在NS2 平台上实现模型性能仿真，利用类MICA2 节点实验床完成原型系统测试。实验结果表明，本项目提出的密钥管理机制和身份认证机制能够有效地保证基于机会主义路由传感器网络中数据通信的安全性。本项目相关研究成果发表EI检索文章3篇，出版相关译著一部，申请相关专利1个。

英文摘要： The opportunistic routing (OR) in wireless sensor networks (WSNs) utilizes the high node density, space diversity and broadcast advantage of wireless communication to increase the reliability of a single transmission by means of setting a set of nodes as the packet forwarder candidates. However, because of the characteristic of OR and the limited resources of WSNs, the existing security mechanisms cannot handle the safety problems in OR WSNs. So we propose an energy-efficient distributed local-area group key management protocol and the corresponding security mechanism: the safety model of the one-to-many communication manner in OR, the localized bilinear-pairing group key management (LBG), the LBG based location key-fingerprint and the corresponding identity authentication. Finally, we evaluated the performance and security of our proposed mechanism by means of NS2 platform and MICA2-like testbed. Experimental results showed that our proposed mechanism could achieve better security, flexibility, correctness, longer lifetime, and adaptability to opportunistic-routing-based WSNs compared with existing mechanisms. Three EI-indexed papers about this project have been published, one patent about this project has been applied and one translated textbook will be published in February，2012.
