Privacy-preserving decentralized method and system to remotely certify the state of an untrusted endpoint

A system to remotely certify a State of an Endpoint from a Backend, the system comprising:

• an Endpoint Orchestrator (EO);
• and
• at least one Endpoint Validator to attest a plausibility of the State wherein:
• the Endpoint Validator-(EV) is distinct from the Endpoint Orchestrator
• the State (S) is based on a series of State Validations (SVi) and a State Function (SF), such that S=SF (SVi),
• the State is known to the Backend and the Endpoint,
• the State Function is known to the Backend and the Endpoint,
• the series of State Validations are unknown to the Backend but known to the Endpoint,
• and wherein the system is configured to verify the Plausibility of the State with the following conditions:
• the Plausibility represents an analysis of information within the Endpoint that supports the accuracy of the State,
• the Plausibility is known to the Backend through the Endpoint Orchestrator,
• the Plausibility (P) is based on a series of Plausibility Validations (PVj) and a Plausibility Function (PF), such that P=PF (PVj),
• the Plausibility Function and the Plausibility Validations are updated in a dynamic fashion,
• the Plausibility Function and the Plausibility Validations are unknown to the Backend, to protect privacy of the Endpoint,
• the Plausibility Function is unknown to the Endpoint, to make tampering of the Plausibility difficult,
• the Plausibility Function is computed by the Endpoint Orchestrator,
• the Plausibility Validations are computed by the Endpoint Validators based on a series of Endpoint Data that are unknown to any party except the Endpoint.
