A method and devices for verifying the integrity of an electronic device having connected thereto at least one connectable or disconnectable component. The method can include obtaining (D) information specific to at least one connectable or disconnectable component, the information being stored in the connectable or disconnectable component; preparing (E) a temporary first master value on the basis of the information specific to the at least one connectable or disconnectable component; and authenticating (E) the temporary first master value by using a previously-prepared second master value in order to determine the integrity of the electronic device.

Method of verifying the integrity of an electronic device, and a corresponding electronic device

In an electronic device designed to function in a trusted execution environment (TEE), because of the execution of a trusted operating system by a processor of the electronic device, or in a rich execution environment (REE), a method of loading files into random access memory includes the following steps: An associated electronic device is also proposed.
