The Key Management Scheme for the WMSN-based Post-Disaster Road Monitoring System

摘要：

　　In order to obtain the availability of roads and bridges after earthquake,a real-time monitoring system is build by wireless sensor networks.And a new key management scheme is proposed to protect the safety of the system.The scheme is based on the polynomial and the Chinese Remainder Theorem,divided into three stages which are system initialization,key establishment,node join and revocation.Analysis shows that the new scheme greatly reduces the storage space and the energy consumption of calculation and communication of node.It is suitable for post-disaster road monitoring system.
