Method for managing an architecture and associated architecture

A secure system comprising:

• a main platform, wherein the main platform is a programmable microprocessor, the main platform including:
• a plurality of partitions for executing software;
• and
• a plurality of first transceiver elements, each first transceiver element being associated with one of the partitions;
• at least one secondary platform, said at least one secondary platform being a programmable microprocessor, wherein the main platform and said at least one secondary platform at least share a communication interface able to ensure exchange of data in cut-off between the main platform and said at least one secondary platform, and wherein each secondary platform comprises:
• a plurality of processing members;
• and
• a plurality of second transceiver elements, each second transceiver element being associated with one of the processing members, and
• a specific driver disposed on each partition,
• wherein each processing member applies processing operations secured for the account of at least one partition,
• wherein each processing member being physically partitioned relatively to the other processing members,
• wherein each driver ensuring a secured link between the partition and at least one processing member with which the partition is associated, and
• wherein the secured link provides encrypted communication between the first transceiver element associated with the partition and the second transceiver element associated with the at least one processing member.

A method for managing an architecture, the architecture comprising:

• a main platform comprising a plurality of partitions executing software, wherein the main platform is a programmable microprocessor, and
• at least one secondary platform, said at least one secondary platform being a programmable logic circuit, and each secondary platform comprising a plurality of processing members, each processing member being able to apply secured processing operations for the account of at least one partition and each processing member being physically partitioned relatively to the other processing members, wherein the main platform and said at least one secondary platform at least share a communication interface able to ensure exchange of data in cut-off between the main platform and said at least one secondary platform,
• wherein each partition comprises a first transceiver element and each processing member comprises a second transceiver element, and
• wherein each partition is associated with one or several processing members, said processing members not being associated with other partitions, the method comprising at least:
• associating each partition of the main platform with at least one processing member by installing, for each partition and each processing member, a driver specific to the relevant partition, the driver ensuring a secured link between the relevant partition and the processing member with which the partition is associated, and
• providing encrypted communication between the first transceiver element and the second transceiver element over each installed secured link.
