A server computing device can determine if a software application executing on a client computing device has not been tampered. Software executes on the server device and communicates either directly or indirectly with an attestation service; a client software application running on the client computing device communicates with the same attestation service. A client software application that is able to calculate a cryptographic hash fingerprint of its executing code image communicates to the attestation service to prove it is untampered with. The attestation service then generates a pass or fail attestation result. The attestation result is communicated between the attestation service and the server computing device. The behaviour of the server computing device is controlled in a way that is conditional on whether a prior attestation of the client software was a pass or fail attestation result. |
