![]() The downside is that the rules of one-time use create a cumbersome key distribution with associated problems. There is no way to crack it with current or future computer power, simply because it is mathematically impossible. The system was invented in 1917 and it is mathematically unbreakable. The key should never be reused and always destroyed after use. One-time encryption, also called one-time pad encryption, is a most basic encryption algorithm where the readable data is combined with a truly random key of the same length as the data. ![]() Let us first explain one-time encryption, and what this paper is about. But there are some things they don’t tell you. They say that current computer algorithms provide enough security and public key schemes solve the problem of key distribution. ![]() Are one-time pads a thing of the past? There has been quite a bit discussion about that, and some security and cryptography experts argue that one-time pad is no longer a system for today’s needs, that it is impractical and creates enormous key distribution problems. ![]()
