Resource-limited Secure Group WSN Management Scheme Based on LNT
Xiaopeng Wang · Journal of Lanzhou Jiaotong University · 2013
In wireless sensor group,the cost of key update process communication,computation and storage in the key update process is excessive,the delay time is too long and also prone to replay attack etc.Consequently,a new resource-limited secure group key management scheme is put forward.This scheme is based on logical neighbor tree principle which generates more logical groups,and each logical group maintains the group key update and management by the group controller without the group node routing support,and at the same time,it has characteristics of confidentiality,robustness etc..Analysis and comparison results show that the new scheme reduces the cost of the communication,computation and storage of the group controller,shortens the key update delay and solves the malicious nodes replay attack issues by implementing lNT construction.
