Abstract: This method comprises the steps of generating an elementary signature for each electronic board from stored configuration data, transmission to each electronic board of the elementary signature, calculation by each electronic board of the signature variable as a function of the configuration variables, and checking by each electronic board of the validity of the stored configuration variables using the received elementary signature and the signature variable. The method comprises the implementation step for each electronic board for which the configuration variables are considered invalid, and comprises the retrieval of the configuration data specific to this board, and the modification of the configuration variables starting from the configuration data retrieved.

Abstract: Disclosed is a method for controlling access to a secure zone of an electronic equipment from a computer file, the equipment including a memory including a reference access right to the electronic equipment. The method includes: —acquiring a reference authenticator via the computer file; acquiring an authenticator from the user; authenticating the user by comparing the authenticator from the user with the reference authenticator; acquiring an access right via the computer file when, at the end of the authentication, the authenticator from the user is compliant with the reference authenticator; and opening an access session to the at least one corresponding secure zone, when the acquired access right corresponds to the reference access right in the memory.
