混沌理论在船舶信息安全系统中的应用

The application of chaos theory in ship information security system

首先重点研究混沌加密中的TEA分组加密,阐述其整个加密、解密的过程;然后根据TEA分组加密的伪随机性和不可测性,在Logisic模型的基础上,提出基于Logisic模型的混沌TEA算法,并且详细描述算法的实现过程;最后通过与DES算法、TEA算法进行对比实验,实验结果表明本文算法在敏感性、抵抗力、速率和实时性方面具有优越性。

Firstly,this paper focused on the TEA group encryption in the chaos encryption. The entire encryption and decryption process was described. According to the unpredictability and pseudorandomness of TEA group encryption and On the basis of Logisic model,chaos TEA algorithm based on the model of Logisic was proposed. Describe the implementation of the algorithm in detail. Finally,experimental results showed that the algorithm had advantages in sensitivity,endurance,speed and real-time aspects.
