摘要
给出一种简单方便且加密性能良好的双Logistic混沌序列加密方案。利用混沌特性和密码学的相关原理,通过Logistic混沌算法生成随机密钥序列,增加文件中的字节存储混乱程度进行加密,并给出缓冲区优化方案。经过实验验证,该方案针对个人文件传输可以起到很好的加密效果,并且加解密速度快,实用性强。
A simple and convenient encryption scheme of double Logistic chaotic sequence with good encryption performance is presented. Using chaotic characteristics and the cryptography correlation principle, and generating random key sequence by Logistic chaos algorithm. The byte storage confusion in the file was increased for encryption, meanwhile, the buffer optimization scheme was proposed. The experimental results show that the design scheme can achieve good encryption effect on personal file transmission,the encryption and decryption speed is fast and practical.
