The one-time pad (OTP) is a theoretically unbreakable cipher. However, in practice it is of limited usability because it requires a pre-shared key of at least the same length as the message. This tool helps you encode or decode one-time pads if you have
Detailed history of one-time pad encryption, images of one-time pads, how they are used and practical examples.
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(中间的部分是加密后的ciphertext) 五、Shannon's perfect secrecy theorem Shannon perfect se...
What is a one-time pad? In cryptography, a one-time pad is a system in which a randomly generated private key is used only once to encrypt a message that is then decrypted by the receiver using a matching one-time pad and key. Messages encrypted with keys based on randomness have the...

1917年,Vernam提出了一种完善保密加密方案,现在被叫做一次一密(one-time pad)。在Vernam提出这个方案的时代,并没有证实其是完善保密加密(perfectly secret);事实上,当时还没有完善保密加密的概念。大约25年以后,香农(Shannon)引入了完善保密加密的概念,并且证实了一次一密能够达到完善保密加密的安全等级。
