RSAprocess
- 本程序所设计的RSA加密解密程序能够有效地生成一对RSA体制中的公钥和密钥,并可实现输入的文本与加密成的密文之间的转换,即完成对所给信息的加密和解密工作.-This program is designed to RSA encryption and decryption process can effectively generate a pair of RSA public key and private key system, the input text can be encrypted
paper(DESusingmatlab)
- 运用matlab实现DES加密解密，可以实现对字符串加密和对文档加密解密，论文-Matlab implementation to use DES encryption and decryption can be achieved on the string encryption and decryption of encrypted documents, thesis
soundsignal
- 将声音文件在时间轴上分割成几段，分别将段的秩序及某些段内的秩序颠倒，从而实现了对声音文件的加密。首先，先读取一个声音信号，对信号做1024点FFT变换，取完点之后，分成四个向量，四个向量组成一个矩阵，再对每一个向量进行转置，再重新整合，从而就实现了回密的过程。-Sound files on the timeline will be divided into paragraphs, each paragraph of the order and reversed the order of some
lsbsoundsignal
- 最不 重 要 位(LSB)方法DO是将秘密数据(水印数据)嵌入到载体数据中最简单的一种方法，它是在时域里隐藏数据。任何的秘密数据都可以看作是一串二进制位流，而音频文件的每一个采样数据也是以二进制数来表示。这样，可以将部分采样值的最不重要位用代表秘密数据的二进制位替换掉，以达到在音频信号中嵌入秘密数据的目的。-The most significant bits (LSB) method of DO is the secret data (watermark data) embedded into
md5
- 本程序是在MATLAB环境下，实现MD5序列的生产，该序列可以用于加密解密算法中。-This procedure is in MATLAB environment, to achieve the production MD5 sequence, the sequence can be used for encryption and decryption algorithm.
aes_rcon
- The permutation function rot_word is declared in Line 1 . The input ”word” w_in is a row vector of four bytes and is cyclically permuted according to Figure 13. In Matlab the permutation can easily be achieved by utilizing the new index vector in
arnold
- 利用matlab写的较基本的arnold加密与相应解密算法，其中的key可以任意改之，但加密次数不宜太多，最好在100次以内-Use matlab to write the basic Arnold encryption and decryption algorithm, one of the key can be arbitrary change, but the number of encryption shoulds not be too much, best within 100 tim
LQFcode
- 用matlab的写的加密程序，目前不支持MultiSelect；基本上可以对任何文件进行加密，但是例如记事本的摘要啊，简介啊无法读取，可以压缩成一个压缩文件后加密。-Wrote an encryption program matlab, does not currently support the MultiSelect basically can encrypt any file, such as Notepad summary of Profile can not read, can be
