Abstract
A root-of-trust of geolocation is provided for an apparatus that includes a trust anchor module with a cryptographic processor and a secure memory. The apparatus further includes a main processor coupled to the trust anchor module and configured to receive a digital geolocation certificate, the geolocation certificate including information identifying the apparatus, information regarding a physical location of the apparatus, information identifying an authorized entity that has verified the physical location of the apparatus, and a digital signature of the authorized entity. The main processor is further configured to cause the trust anchor module to store the digital geolocation certificate in the secure memory such that the digital geolocation certificate is cryptographically bound to the apparatus. The trust anchor module may also include, or otherwise communicate over a secure channel with, a movement sensor associated with the apparatus.
