The present invention relates to the field of computer memory management. It pertains more particularly to a system and method for securing the translation tables stored in a memory external to a secured processor circuit, said secured circuit comprising internal resources defining a secured universe and a processor for executing an application, the processor comprising a hardware mechanism HTW devised so as to issue at least one request to read a translation descriptor during the issuing of a virtual address by the execution of the application, said secured processor module comprising, furthermore, a transcoder intercepting said request under consultation and the response to this request and detecting, so as to generate a computer exception or modify the response, when the translation descriptor received in response to the request associates a virtual address with a physical address of the secured universe. |
