An Encryption Scheme Based on Key Pre-distribution for Wireless Sensor Network in Electromechanical System

This paper proposes an encryption scheme based on key pre-distribution for wireless sensor network (WSN), which fulfills perfectly all the security requirements in WSN using the counter and message authentication code during the encryption process. Furthermore, the related protocols or algorithms are very simple and no expensive public-key operation is required in view of resource-starved sensor nodes, which improves the efficiency of our scheme and makes it be applied in the giant electromechanical monitoring & controlling system.
