希尔
- 不错的希尔代码，希尔是一种经典的加密算法，加密可以通过一线形变换，脱密再做依次逆变换。密钥就是变换矩阵本身。-good code Hill, Hill is a classic encryption algorithms, encryption can transform line shape, followed again from close inverse transform. Key is the transformation matrix itself.

- 独立按键控制，一直以来，独立式按键是一块问题，矩阵键盘也是，希望可以给你带来启发-Independent key control, has been key is a stand-alone issue, the keyboard matrix is also the hope that can give you inspiration
AnImageEncryptionSchemeBasedonChaoticMap
- ieee一种基于混沌的新加密方法An Image Encryption Scheme Based on Chaotic Map - In this paper, a novel block digital image encryp- tion scheme based on a chaotic coupled map lattices (CML) is reported. Within this scheme, an original image is decomp
ASM
- 按键扫描程序 ASM。1. 键盘采用4*5矩阵键盘,含有两个组合键. 2. 硬件连接比较混乱,且各个按键的排列与面贴上的键码对应混乱.如果采用教科书上常规矩阵键盘的 扫描方式实现比较繁琐. 3. 需要识别两个双键,但这两个双键位置比较特殊K17,K18和K19,K20. 4. 基于2,3两点.这里采用列,行分别输出全零,读取行,列的引脚电平信息.综合这两组信息查表获取键值. 对于单键按下,有两个位为0.对于两个按键按下,有3或4个位为0. -Key scanne

aes_key_expand_128
- The key expansion function takes the user supplied 16 bytes long key and utilizes the previously created round constant matrix rcon and the substitution table s_box to generate a 176 byte long key schedule w, which will be used during the en- and
AES
- AES加密过程是在一个4×4的字节矩阵上运作，这个矩阵又称为“体（state）”，其初值就是一个明文区块（矩阵中一个元素大小就是明文区块中的一个Byte）。（Rijndael加密法因支持更大的区块，其矩阵行数可视情况增加）加密时，各轮AES加密循环（除最后一轮外）均包含4个步骤： 1.AddRoundKey — 矩阵中的每一个字节都与该次回合金钥（round key）做XOR运算；每个子密钥由密钥生成方案产生。 2.SubBytes — 通过一个非线性的替换函数，用查找表的方式把每个

Cipher
- 置换密码算法的原理是不改变明文字符，只将字符在明文中的排列顺序改变，从而实现明文信息的加密。置换密码也叫换位密码。 试编程实现矩阵换位密码。它的加密方法是将明文中的字母按照给定的顺序安排在一个矩阵中，然后用根据密钥提供的顺序重新组合矩阵中的字母，形成密文。例如，明文为attack begins at five，密钥为cipher，将明文按照每行6个字母的形式排在矩阵中，如下形式： a t t a c k b e g i n s a t f i v e 根据密钥ciphe
