基于混沌序列的通用加密解密方法及实现

On the Method with Implementation of Universal Encryption and Decryption for Computer Files Based on Chaotic Sequence

分析了常见的文件在计算机中的存储方式,根据计算机文件的特征,提出直接对二进制数据进行处理的计算机文件通用加密解密方法。依据混沌序列具有良好随机性的特点,提出利用Logistic映射序列密码对计算机信息进行加密、解密的方法,并用Visual Basic 6.0实现了该方法。这种方法能够用于对计算机中的任何文件进行加密解密。

According to the storage methods and characteristics of computer files,this paper presents a general encryption and decryption method of a computer file by directly processing on the binary data. Because the characteristics of the chaotic sequence is of fine random,the encryption and decryption method is proposed for the computer information by using the cipher of the logistic mapping sequence and the method is realized by Visual Basic 6. 0. This method can be used for any file in the computer.
