The method involves dividing a set of safety modules (SC) into groups, and determining an asymmetrical key comprising a public key and a set of private keys, for each group. One of the private keys is loaded by using a safety module. A safety message is transmitted for each group, where the message is encrypted by the public key of the group. One of the modules of the groups is removed by sending a new private key to the modules of the group comprising the module to be removed, where the new key corresponds to the public key of the other group and is encrypted by a personal key of the module. |
