METHOD FOR GENERATING AN EVIDENCE OF THE TIME ELAPSED BETWEEN EVENTS IN AN ASYNCHRONOUS NODE NETWORK

A method for generating an evidence of the time elapsed between two successive events occurring within a node of an asynchronous network, for example between two transactions emitted by such a node intended to a distributed register (ledger). The node is provided with an embedded system comprising a...

Zusammenfassung:A method for generating an evidence of the time elapsed between two successive events occurring within a node of an asynchronous network, for example between two transactions emitted by such a node intended to a distributed register (ledger). The node is provided with an embedded system comprising a TPM module generating a control clock, a system clock within a TEE environment and a precision clock. The node verifies the coherence of the clocks by comparing the measurements of the time elapsed between two successive transactions, the measurements having been performed by means of the different clocks. In case of coherence of the measurements, the node emits a transaction proving the elapsed time intended to the distributed register. A verifier node may verify this evidence and certifies that the evidence is verified by emitting a validation transaction to the distributed register.
