Low-energy Group Key Management Scheme for Wireless Sensor Network Based on Identity
Guan Ya-we · Jisuanji gongcheng · 2014
In clustering Wireless Sensor Network(WSN),within the cluster nodes often multicast,to guarantee the security of message and node information,this paper designs a flexible and efficient group key management scheme.In this scheme,the calculation of the initial set of keys and group key update when node exits,are based on the identity of the broadcast encryption algorithms,the algorithm reduces the length of the broadcast message and transport energy consumption.The new node to join and the key at the end of life period of group key update use symmetric encryption method of energy consumption.This scheme can resist conspiracy attacks,counterfeit attack.Security analysis results show,under the same security standard,compared with other schemes such as EGKAS,this scheme takes up less storage space,lower energy consumption,and storage and group key update is independent of the size,has a good scalability.
