| 摘 要： | 针对无照料的无线传感网（UWSN, unattended wireless sensor network）收集效率和安全问题，提出一种安全的UWSN分簇方案，实现了一种三角形网格图的网络拓扑分簇算法，并可完成簇头对移动节点的认证。该方案利用三角形的性质提高了网络的连通度，折中数据收集效率与能耗；将分布式密钥共享方案与分簇算法无缝结合，在网络中高效地搜索移动节点公钥信息，从而在本地不存有对应公钥信息的情况下验证签名信息。实验结果表明，该算法在节点密度越大的情况下分簇越趋近于正三角形网格图，且分簇后的网络对于低于20%节点变节有95%以上概率抵御攻击。

| Abstract: | For unattended wireless sensor network (UWSN), considering the collecting and efficiency and security problems, a secure clustering scheme for UWSN was proposed, which implements a clustering algorithm with the secure authentication of mobile nodes. The clustering algorithm uses triangle's characteristic to improve connectivity, balances collect efficiency and power consumption. The distributed key sharing scheme is used to improve the security of the clustering algorithm, in which mobile node's public key is able to be searched with high efficiency in the distributed static nodes, and the signature of mobile nodes will be checked by using the searched public key. Simulation results show that the clustering algorithm is tend to triangular meshes when node density is increasing, and more than 95% attacks are tolerated when compromised nodes are less than 20%. |
