Safety device partitioning between first and second domains, enhanced with audit functionality

摘要

the equipment (10) comprises: a physical layer processor (20), compotant partitioning mechanism, a material storage means and a memory; a layer of virtualization (30) comprising a core and a hyperviseur; and an application layer (40) consisting of: the first and second interface components (41, 42).in order to exchange data with the first and second areas, and a security component (44) to form a chamber for the exchange of data between the first and second components.it is characterized in that the safety component (44) includes a means (47) for generation of metadata, and a means (48) for writing the metadata in a shared memory (50) that, in the application layer (40) comprises a component (46) auditwith a means (52) for reading metadata in the shared memory, and a means (54) for the treatment of metadata are read.
