For the transmission of information with verification of transmission errors , a useful information message (M) is transmitted in a determined frame while being associated with a determined number p of transmission error verificati on bits (CRC,S) also transmitted in the frame. In order to have an element allowing the verification of intentional errors, determined number p1 of the transmission error verification bits form a seal (S) obtained from a determined sealing function, where p1 is a number less than p. Application t o radiocommunications equipment requiring the verification of the integrity an d the authentication of the messages transmitted. |
