第七讲 流密码的基本概念 一次一密密码(one-time pad) 一次一密密码又称一次性板子,是一种绝对安全的密码,但是非常不实用。 如下图所示,明文和密钥都是字符串,经过异或之后生成密文。 其绝对安全性来自密钥完全随机,而且只使用一次。 具体加密流程如下图所示: 一次一密密码缺点和优点一样明显: 优点: 密钥完全...
不知道你是否相信,只需 10 行代码,就可以使用Python100% 安全地加密文件。这背后的原理就是 OTP。 原理 OTP 就是 One-time password,翻译过来就是一次性密码。它的原理非常简单,加密的过程就是明文和密钥(key)进行异或,得到密文,而解密的过程就是密文和密钥(key)异或,得到明文。举例如下: 加密(此处图贴错了,...
3.一次性密匙(one time pad) 你拥有一个密码本,上面全部都是偏移量相关 例如:一个4长度的单词的加密 是 1334 一个10长度的单词的加密 是 9868978909 这样就是完整的加密了,不过比较麻烦 4.德军的恩尼格码 三个转子 每个转子的初始位置不同,会导致密码表完全不同,并且一个字母除了其本身之外,可以突变为任意...
