一种基于多项式的无线传感器网络密钥管理方案
Key management scheme based on polynomial for WSN
摘要
Abstract
This paper presented a key management scheme based on polynomial for wireless sensor network ( WSN). The base station calculated the polynomial formed by the secret information of the nodes to generate a global network key, through which the nodes could certify the legitimate nodes in the network. The nodes generated the unique session keys between the neighbor nodes through the global network key after Diffie-Hellman key exchange. This scheme could dynamically update the keys so as to solve several problems such as; information disclosure when some nodes were captured, the decline of key connectivity and higher communication overhead when key was renewed. The analysis of performance show that this scheme has a lower storage cost, a lower communication overhead, good scalability and connectivity, compared to some existing pre-distribution schemes.关键词
