Efficient Key Management Scheme for Data-centric Storage Wireless Sensor Networks
Pan Zhong-qian · 2014
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.
