Key management scheme for post-disaster road monitoring system
Yang Qiuge · Computer Engineering and Applications Journal · 2013
A real-time monitoring system is put forward by wireless sensor networks to obtain the availability of transport lifeline after earthquake.A new key management scheme based on polynomial and Chinese remainder theorem is proposed to protect the safety of the system.The scheme is divided into three stages such as system initialization,key establishment and node join and revocation.By analyzing,it shows that the new scheme greatly reduces the storage space,calculation and communication energy consumption of node.It is suitable for post-disaster road monitoring system.
