The invention relates to a method for managing an architecture, wherein the architecture comprises a main platform including a plurality of partitions for executing software, and at least one secondary platform. The method further comprises at least one step of 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 operating member(s) with which the partition is associated.

Method for managing an architecture and associated architecture

A method is provided for defining a filtering module between a first module processing information with a first sensitivity level, and a second module processing information with a second sensitivity level connected, in parallel with the filtering module, by a cryptographic module. The method includes defining a set of filtering rules in a language that can be compiled, defining the properties of messages whereof transmission is allowed between the first and second modules; validation processing the predefined set of rules, validating that a transmission authorization or refusal has in fact been provided by applying the set of rules to any information that may be provided at the input of the filtering module; compiling the predefined set of rules; and integrating the compiled set of rules into a rules database of the filtering module.
