Abstract: Remote attestation is a very important mechanism helping a trusted party to get the status of a remote embedded device. Most remote attestation schemes aim at checking the code integrity and leave devices vulnerable to runtime attacks. Recently a new kind of attestation called control flow attestation has been proposed to get rid of this limitation. However, previous studies on control flow attestation cannot verify the attestation result efficiently and lack secure storage.
