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
