Providing a suitable key establishment scheme in wireless sensor networks is challenging due to all the characteristics of these networks,such as dynamically changing topology and limitations of power,computation capability and storage resources.This paper presented a key pre-distribution scheme using Hamming distance which was suitable for wireless sensor networks.In this scheme,Hamming distance,asymmetric and symmetric cryptography were employed to achieve key pre-distribution and exchange in wireless sensor networks.The proposed key predistribution scheme has advantages over random key predistribution scheme in its security and only spends moderate computation cost,so it is quite practical.
