Abstract: Embodiments of systems and methods disclosed herein include an embedded secret provisioning system that is based on a shared-derivative mechanism. Embodiments of this mechanism use a trusted third-party topology, but only a single instance of a public-private key exchange is required for initialization. Embodiments of the system and methods are secure and any of the derived secret keys are completely renewable in untrusted environments without any reliance on asymmetric cryptography. The derived secrets exhibit zero knowledge attributes and the associated zero knowledge proofs are open and available for review. Embodiments of systems and methods can be implemented in a wide range of previously-deployed devices as well as integrated into a variety of new designs using minimal roots-of-trust.

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.

Abstract: Embodiments of systems and methods disclosed herein include a distributed device activation mechanism involving a group of external entities without using asymmetric cryptography. Systems and methods include techniques for deriving a device secret using a hardware secret and authenticated unique input data provided to the device by one or more external entities. A hardware hash function uses the hardware secret as a key and the authenticated unique input data as input data to output the derived device secret. The derived device secret is written to a security register of the device to enter a new security layer.
