Estimating the term…
The invention relates, according to a first aspect, to electronic equipment comprising a processor (2), a memory (11) and a communication module (3) ensuring an interface with an avionics data network, characterized in that the communication module (3) and processor (2) are embedded within a microcontroller (1) so that the memory (11) is shared between the processor and the communication module, and in that it furthermore comprises a module for monitoring the accesses to the memory (17) which are configured so as to detect an access or the communication module (3) into an unauthorized address area (12) of the memory (11). According to a second aspect, the invention relates to a method of making a processor secure against the failures of a complex peripheral.
Electronic equipment comprising a processor (2) programmed to execute a function, a memory (11) and a communications module (3) ensuring an interface with an avionics data network, characterised in that the communications module (3) and the processor (2) are onboard a microcontroller (1) such that the memory (11) is shared between the processor and the communications module, and in that it also comprises a surveillance module for access to the memory (17) configured to detect access of the communications module (3) in a non-authorised address zone (12) of the memory (11).
A process of securing electronic equipment comprising a processor and a communications module ensuring an interface with a network of avionic data, the processor and the communications module being onboard a microcontroller such that they share the same memory, comprising using surveillance of access to the shared memory to detect access of the communications module in a non-authorised address zone.
