Abstract: 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: reception (E10) by the trusted operating system of information (L1) identifying at least one file; verification (E11) by the trusted operating system of the conformance of the identified file to at least one given criterion; in the event of conformance, loading (E13) the identified file into an area (Z2) of random access memory accessible in read only mode when functioning in the rich execution environment (REE). An associated electronic device is also proposed.
