1. A computing device for attesting itself to a communication partner, comprising: a communication port configured to receive an attestation request from the communication partner; and an application-specific integrated circuit (ASIC) configured to: receive the attestation request from the communication port, the attestation request including a nonce generated at the communication partner; generate a verification value, wherein the verification value is a computation result of a predefined function taking the nonce as an initial value; capture data representing at least one intermediate result of computation of the predefined function on the ASIC; and send the verification value and the captured data to the communication port to be transmitted back to the communication partner, wherein the communication partner performs the predefined function taking the captured data as an initial value and in parallel performs the predefined function taking the nonce as an initial value to determine whether the received verification value is equal to an expected value.
