Zusammenfassung:Aspects may relate to a device to provide trusted time assurance. The device may comprise: a time clock; an interface; and a processor coupled to the interface. The processor may be configured to operate a trusted execution environment to: receive a request through the interface from a server to send current time; receive a nonce from the server through the interface; sign the current time from the time clock, the nonce received from the server, and device information with an attestation key; transmit the signed current time, nonce, and device information to the server through the interface. The device may then receive an application, a service, or data and a defined period of time from the server through the interface to be available for use for the defined period of time measured by the trusted execution environment.
