The only proven unbreakable encryption method

One Time Key encryption - the only proven
unbreakable encryption method

Characteristics of the One Time Key encryption method

The One Time Key encryption method is a binary additive stream cipher, where a  stream of truly random keys is generated and then combined with plain text for encryp -tion or with ciphertext for decryption by an ‘exclusive OR’ (XOR) addition.It is possible to prove a stream cipher encryption algorithm is unbreakable if the following preconditions are met:
  •                             The key must be as long as the plain text
                        
  •                             The key must be truly random
                        
  •                             The key must only be used once
