针对pDCS( Security and Privacy Support for Data-Centric Sensor Networks)方案在密钥重置时信息交互量大的问题,以互斥基底系统( Exclusion Basis System,EBS)建构一个高效能的分布式密钥管理方案。该方案将网络密钥的管理工作(包括密钥分配、重置及撤销)分散至各个簇中,进而降低密钥重置阶段通信量,延长网络寿命。论证分析表明：在不失安全性的前提下,仅增加些微的储存成本,便能大幅地降低能耗。

In order to reduce the rekeying messages needed in key management task,based on the Exclusion Basis Systems( EBS) ,we propose an efficient distributed key management scheme. It attempts to distribute the key man-agement tasks, including key distribution, rekeying, and key revocation, to each cluster to reduce the number of rekeying messages. The results show that,comparing to the pDCS scheme,the ERP-DCS is superior,in terms of up-date messages needed in the rekeying process,while at a little cost in key storage.
