Summary:A verifier device in one embodiment is configured to communicate over one or more networks with a client device and a server device. The verifier device participates in a three-party handshake protocol with the client device and the server device in which the verifier device and the client device obtain respective shares of a session key of a secure session with the server device. The verifier device receives from the client device a commitment relating to the secure session with the server device, and responsive to receipt of the commitment, releases to the client device additional information relating to the secure session that was not previously accessible to the client device. The verifier device verifies correctness of at least one characterization of data obtained by the client device from the server device as part of the secure session, based at least in part on the commitment and the additional information.
