摘要
针对无线传感器网络能量、存储空间、通信开销等局限性问题,基于pDCS(Security and Privacy Support for Data-Centric Sensor Networks),在保证不失其安全性的前提下,以互斥基底系统(Exclusion Basis System,EBS)建构一个具有更高效率的分布式密钥管理方案,将其命名为ERP-DCS。该方案将网络密钥的管理工作(包括密钥分配、重置及撤销)分散至各个簇集中,藉以降低密钥重置阶段所需的通信量,节省能源,进而延长网络寿命。论证分析表明,与pDCS相比,ERP-DCS仅增加了些微的储存成本,却能大幅地降低密钥重置时的更新通信量。
Based on the Exclusion Basis Systems（EBS）,we proposed an efficient distributed key management scheme,termed as ERP-DCS,to improve the deficiencies identified in the pDCS scheme.ERP-DCS attempts to distribute the key management tasks,including key distribution,rekeying,and key revocation,to each cluster（i.e.grid cell）to reduce the number of rekeying messages.The results show that,comparing to the pDCS scheme,the ERP-DCS is superior,in terms of update messages needed in the rekeying process,at a little cost in key storage.
