VERIFICATION OF MAC CODE WITHOUT DISCLOSURE |
摘要 |
The invention relates to a verification of the authenticity of a message (M) transmitted by a transmitting unit (95) to a receiver unit (96) with a cryptographic redundancy corresponding to a message authentification code (MAC) calculated from a block encryption. According to the invention, instead of verifying the code (MAC) received with the message (M) on reception,An initialisation vector (IV) value is deduced from the received code (MAC) which is compared with a previously stored reference value (IV). |
