Abstract: This paper presents a key management-scheme based on trust mechanism. Through evaluating trust values of the originating node, it can determine whether these nodes are selected as the cluster-head ones to realize key updating. With a two-way trust packet forwarding mechanism, this scenario can not only get the trust value of each node, but also verify the correctness of the trust packet. In addition, it may further improve the corresponding security of the key management implementation. Meanwhile, this paper does theoretical research and analysis from the aspect of security, communication n complexity and memory consumption, and the corresponding experimental simulation obtained.


Keywords: Trust mechanism, Key management, Wireless sensor networks, Polynomial function, Secret key.
