摘要
利用混沌影射的方法设计了一种多随机性的文件加密算法.分析了数据加密和Logistic混沌映射的原理,提出了基于混沌方法的多随机性文件加密算法,采用VB完成了文件加密软件的设计.软件测试表明:该加密算法的混沌特性和多随机特性增加了解密的难度,提高了加密数据的安全性,实现了密钥的随机生成和加密算法的随机调用,使得加密后的文件更加安全.
A multiple random file encryption algorithm is presented based on the Logistic chaos method. The basic principles of data encryption and Logistic chaos are analyzed, and the file encryption software by using VB is designed. Software testing results show that the chaos character and the multiple random character of the algorithm increase decryption difficulty and the security of encrypted data. The method implements the random creation of secret key and the random call of encryption algorithm, which can increase the security of encrypted files.
