A method (200) for transmitting a message between a first electronic device (C) and a second electronic device (MS i ) is described, comprising steps of:
- implementing an encryption algorithm, generating (202), by the first electronic device (C), a first data encryption key (K i ) identifying the second electronic device (MS i ) on the basis of a main data encryption key (MK) and an identification code (ID i ) of the second electronic device (MS i );
- implementing said encryption algorithm, generating (203), by the first electronic device (C) and the second electronic device (MS i ), a communication key (K di ) on the basis of said first data encryption key (K i ) and a reference datum (DT). |
