key和code都太长了,我就不列出来了,感兴趣的可以自己运行一遍上面的代码。 这里针对我们的plaintext m我们的key k只使用一次,每当我们换一个新的m的时候,我们也要重新生成一个新的k。 这个One time pad满足我们的perfect secrecy,在此就不证明了,而是举一个非常简单的例子: 一个非常简单的示例(中间的部分是加...
Key stream is generated by true randomness Why can't One Time Pad be Broken? You can decrypted to any plaintext available in the universe with that length. import random def generate_key_stream(n): return bytes(random.randrange(0, 256) for i in range(n)) def xor_bytes(key_stream, me...
