Abstract
In the power system for wireless sensor networks special working environment. The net works in special environment, the node, with the characteristics of small bulk, the little memory resource, lower operation and little energy, can not be reused, the wireless network thus has special requirements for the security. Based on the characteristics of wireless sensor networks was proposed based on chaotic key block encryption algorithm. Based on the characteristics of wireless sensor networks was proposed based on chaotic key block encryption algorithm. Chaos expansion algorithm uses integer keys, the improved RC6 encryption plaintext shift operation, use cipher text feedback modify the control parameters to the relevant key and cipher text, effective against plaintext attack. The simulation results show that the security of the algorithm is high and fit for WSN.
