Abstract
A system, devices and methods for verifying an administrator computing device to a guest computing device, verifying the guest device to the administrator device and outputting a list of the guest device capabilities for the administrator device such that the guest device is capable of verifying the administrator device, for example to ensure it does not divulge its capabilities to imposters, and the administrator device is capable of identifying whether the list of device capabilities is authentic. Verification can be achieved through cryptographic hashes of private certificates, digital signatures or expected output from verified modules. The list of device capabilities may be restricted based on the authorization granted to the administrator computer and may be altered or watermarked for verification. A failure to verify the administrator device may restrict execution of instructions on the guest device to prevent unauthorized access to the guest device's capabilities.
