Abstract
In authentication in global attestation, a server receives a request for access to a location based service. The server establishes a connection with a first device and with a second device, wherein the devices are connected by a location bounded network. The server sends a key order information to the first device and a first plurality of keys to the second device. The server receives a second plurality of keys from the first device, wherein the second plurality of keys is an ordered set of keys compiled using the key order information and the first plurality of keys. The server determines that the second plurality of keys received from the first device matches an expected plurality of keys. The server outputs, to the location based service, a notification indicating a result of the determining that the second plurality of keys matches the expected plurality of keys.
