Abstract
A method of attestation of a host machine based on runtime configuration of the host machine is provided. The method receives, at an attestation machine, a request from the host machine for attestation of a software executing on the host machine, the request including at least one security-related configuration of the software at launch time and a corresponding runtime behavior of the software when the security-related configuration changes. The method then generates a claim based on evaluating a value associated with the at least one security-related configuration and the corresponding runtime behavior of the software when the value changes. The method also generates an attestation token after a successful attestation of the software and include in the attestation token the generated claim. The method further transmits the attestation token to the host machine.
