摘　　要：为获得地震灾后交通生命线的损坏程度,利用无线传感器网络搭建实时监测系统。为保障系统的安全性,提出一种新的密钥管理方案。该方案基于多项式和中国剩余定理,分为系统初始化、密钥建立、节点的加入和撤销三个阶段。分析表明,新方案大大节约了节点的存储空间、计算能耗和通信能耗,适用于灾后道路可用性监测系统。A real-time monitoring system is put forward by wireless sensor networks to obtain the availability of transport life- line after earthquake. A new key management scheme based on polynomial and Chinese remainder theorem is proposed to pro- tect 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 communica- tion energy consumption of node. It is suitable for post-disaster road monitoring system.
