Key Pre-Distribution Scheme for Wireless Sensor Network against LU Attack
Zhong Min Xiao · Chinese Journal of Computers · 2013
Existing key pre-distribution schemes based on LU decomposition are suffering from LU attack.In order to solve this problem,perturbation technology is an effective method to break the relationship between result matrices of LU decomposition,and random cutting method of shared bit-string is also introduced to enhance the difficulty of breaking share keys.Based on these two methods,a new pair-wise key pre-distribution scheme against LU attack is proposed.Nodes only need to preload a few of key materials and can establish pair-wise keys with high security by choosing proper parameters,such as the noise factor,the length of key component,the total number of rounds.The contrastive analysis and feasibility analysis show that our proposed scheme is suitable for wireless sensor networks and resistant to eavesdropping attack,LU attack and node capture attack.
