Self-corrector randomising-encrypting system and method such that being supplied input data sequence (X) and control block (K) always generates randomised-encrypted data sequence, which is an at random number sequence. Signature generating-assembly device (601) with data sequence (X) generates signed plaintext sequence (XF) supplied to randomising-encrypting device (102), where it is grouped with candidate control block (KC), which is generated by candidate control block generator (801) with control block (K), and generate suggested randomised-encrypted text sequence (AP) supplied to randomness verifier (603), which validates sequence randomness. If suggested randomised-encrypted text sequence (AP) is at random, it is supplied as randomised-encrypted text sequence (A); if it is not at random, the candidate control block generator (801) generates new candidate control block (KC) in order to randomise-encrypt the signed plaintext sequence (XF) again. The iteration is repeated until suggested randomised-encrypted text sequence (AP) is at random. <IMAGE> |
