自毁程序
鉴于单纯设置一个计数器易被查出,通过修改使其不起作用。我们设计的程序可以通过数据文件,软件执行前通过关键字找到计数基数,然后计算和判别,如果在合理范围,则设定新的关键字,将计数基数放在新关键字指定的位置,并执行子程序 则启动自毁程序。

128192和256位密钥的密码Twofish的VHDL实现。
VHDL implementation of the twofish cipher for 128,192 and 256 bit keys.
The implementation is in library-like form All needed components up to, including the round/key schedule circuits are implemented, giving the flexibility to be combined in different architectures (iterative, rolled out/pipelined etc). Manual in English is included with more details about how to use the components and/or how to optimize some of them. All testbenches are provided (tables, variable key/text, ECB/CBC monte carlo) for 128, 192 and 256 bit key sizes, along with their respective vector files.-VHDL implementation of the twofish cipher for 128,192 and 256 bit keys.

视觉密码
视觉密码的想法是一个迷人的发明由摩尼 Naor 和阿迪沙米尔 (1994 年)。在最简单的形式,它实现了牢不可破的 (在信息理论的感觉) 加密系统,而是类似于一次性垫,额外的转折,解密不需要任何计算设备。詹姆斯 · 邦德运载一个特别"键",其实是一种透明度以多个随机点上 ;当 M 传真债券秘密消息,它太组成的多个随机点债券只在密文的地方他的透明度并读取出明文 !天才在这里的脑卒中是一项技术,解释了海报,通过视觉开展的"异或"的布尔操作中"。我决定实施该系统后看到示范在一次辉煌的阿迪沙米尔本人谈话。http://www.cl.cam.ac.uk/~fms27/vck/
