Reputation model based pair-wise key establishment algorithm for sensor networks
Fen-hua Cheng · Journal of Computer Applications · 2011
Based on the key pre-distribution scheme,a new pair-wise key establishment method was proposed for sensor networks,in which each node was pre-assigned with an initial global key before deployment.And after deployment,the node can dynamically establish different one-hop pair-wise key on the basis of the pre-assigned global initial key.The theoretical analysis and simulation results show that the new algorithm has better probability of direct and indirect pair-wise key establishment than the traditional random pair-wise key establishing scheme for sensor networks.
