Classification: CPC H | IPC H

Claim 15:
16. A destination device intended to receive a communication from a source device through a circuit comprising at least one relay and belonging to a computer network comprising at least one shared memory, the destination device comprising a processor configured to implement a communications capability receiving a request for generating a proof of use, called a PoU frame, coming from the source device and containing at least one signature made from a challenge and a key proper to each of the at least one relay of the circuit, the PoU frame comprising a value of the challenge used by each of the at least one relay to compute the signatures, a verifying capability configured to authenticate signatures of the PoU frame in using the public keys of the at least one relay of the circuit, the authentication of the signatures by the verifying capability triggering a sending by the communications capability of transaction frames addressed to each of the at least one relay identified in the circuit to generate proofs of use of each of the at least one relay, the transaction frames comprising at least the signatures contained in the PoU frame being designed to trigger the sending by each of the at least one relay of a proof of use recorded in a shared memory.
