Improved key-management scheme for wireless sensor networks. (Chinese. English summary) Zbl 1181.68020

Summary: This paper proposed an improved matrix key-distribution scheme for wireless sensor networks. This scheme can delete and update key information with the network topology changes to avoid key information to be revealed. Also, based on the clustered structure, this scheme can reduce communication-computation and key storage overhead, which can solve the problem that each sensor node has limited resource. Comparison and simulation results show that the proposed scheme has higher network security and lower key storage overhead than most of the existing key management schemes.
