基于混沌的水下传感器网络分组加密算法
A Block Encryption Algorithm Based on Chaotic Theory for Underwater Sensor Networks
摘要
Abstract
Underwater acoustic channel is open, and underwater sensor networks are more vulnerable to be attacked and threatened.To solve the security problem of UWSN, we present a block encryption algorithm based on chaotic theory.It adopts 16-round iteration Feistel structure to encrypt and decrypt block.The round function is constructed by discrete coupled chaotic systems.The round keys are generated by logistic mapping.By analysis, our algorithm can meet security requirements, and can resist adversarial attacks.Simulation results show that, compared with DES and AES algorithms, our algorithm has higher energy efficiency and can be applied to UWSN.关键词
