Abstract
A method for attestation of Control Flow Integrity (CFI) of an application running on an end entity whereby an asymmetric key pair is generated by a Key Management Module (KMM) comprising a private key and a public key, then the public key is signed with a device key unique to the end entity thereby generating a public key certificate which attests to the private key being in possession of the end entity. The asymmetric key pair is based on the executing code of the application and the device key. The attestation claims regarding CFI of the application are signed by the private key in a dedicated signature module.
