Abstract (en)
[origin: WO2009047325A1] The invention relates to a device and a method for directing exchange flows for public or non sensitive values for creating common secret keys between several areas in a system where entities communicate between them by trust groups, characterised in that it comprises at least the following steps: each entity generates a public value and communicates said public value to a router; said router includes a correspondence table for matching a virtual network number and the MAC addresses of the associated entities, and recovers all the public addresses transmitted by the entities by associating them with their MAC address and retransmits to each of said entities the public value of another entity belonging to the same trust group; each entity recovering the public value of another entity belonging to the same trust group then determines the value of the ciphering key common to the entities of a same trust group, and uses that key for ciphering the data to be transmitted to another entity.
