New clustered key-management scheme based on LU matrix for wireless sensor networks
无线传感器网络中基于LU分解的分簇密钥管理方法

This paper proposed a new key-management scheme for wireless sensor networks.Based on the LU matrix,this scheme could pre-load some key information to sensors to insure the establishment of secure link.The analysis shows that the scheme can cost lesser key storage overhead,and can delete and update key information with the network topology changes to avoid key information to be revealed.
