MANET Security Communication Model Based on Multistage Chaotic Encryption

文章在混沌加密/解密原理和混沌模型基础上,设计了一个多级混沌加密算法,并构建了一个MANET安全通信模型。同时,在该模型中实现了两组明文的加密/解密仿真实验,并对得到的仿真结果在密文字符频率统计以及雪崩效应方面进行了分析。仿真实验表明:MANET安全通信模型有实现简单,随机性好,加密强度高,加密速度快的特点。

Based on chaotic encrypting/decrypting principle and chaotic model,this paper designs a multistage chaotic encryption algorithm and constructs MANET security communication model.Simultanelty,this paper implements some simulating experiments which two group plaintexts are encrypted or decrypted in MANET security communication model. This paper also analyzes the instances about cryptographs char frequency statistic and snowslip effect of experiment datum.Simulating experiments state that the MANET security communication mode has some characteristics which are simple in implementation,well in random,high intensity in encrypting and fast speed in encrypting.
