Abstract: A method (400) for remote attestation includes establishing, using a cryptographic protocol (20), a communication session (22) between a first computing device (10a) and a second computing device (10b). The communication session includes communications encrypted by an ephemeral session key (24). The method includes receiving, at the first communication device via the communication session, from the second computing device, an attestation request (172) requesting the first computing device to provide an attestation report (162). The method includes generating, by the first computing device, the attestation report based on the ephemeral session key and sending, using the communication session, the attestation report to the second computing device.
