Improved key-management scheme for wireless sensor networks
无线传感器网络中一种改进的密钥管理方案

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 s...
