Abstract
Embodiments as described herein provide systems and methods for sharing secrets between a device and another entity. The shared secret may be generated on the device as a derivative of a secret value contained on the device itself in a manner that will not expose the secret key on the device and may be sent to the entity. The shared secret may also be stored on the device such that it can be used in future secure operations on the device. In this manner, a device may be registered with an external service such that a variety of functionality may be securely accomplished, including, for example, the generation of authorization codes for the device by the external service based on the shared secret or the symmetric encryption of data between the external service and the device using the shared secret.
