Abstract
In one example a prover device comprises one or more processors, a computer-readable memory, and signature logic to store a first cryptographic representation of a first trust relationship between the prover device and a verifier device, the first cryptographic representation based on a pair of asymmetric hash-based multi-time signature keys, receive an attestation request message from the verifier device, the attestation request message comprising attestation data for the verifier device and a hash-based signature generated by the verifier device, and in response to the attestation request message, to verify the attestation data, verify the hash-based signature generated by the verifier device using a public key associated with the verifier device, generate an attestation reply message using a hash-based multi-time private signature key and send the attestation reply message to the verifier device. Other examples may be described.
