摘要： Apparatuses, methods, and systems for reconfiguring a secure system are disclosed. In one embodiment, an apparatus includes a configuration storage location, a lock, and lock override logic. The configuration storage location is to store information to configure the apparatus. The lock is to prevent writes to the configuration storage location. The lock override logic is to allow instructions executed from sub-operating mode code to override the lock.

摘要： Some implementations disclosed herein provide techniques and arrangements for provisioning keys to integrated circuits/processors. A processor may include physically unclonable functions component, which may generate a unique hardware key based at least on at least one physical characteristic of the processor. The hardware key may be employed in encrypting a key such as a secret key. The encrypted key may be stored in a memory of the processor. The encrypted key may be validated. The integrity of the key may be protected by communicatively isolating at least one component of the processor.

摘要： One aspect of an embodiment of the invention provides a method, system, and device to prove to a challenger that a prover device has a signature from a device manufacturer without revealing the signature to the challenger. According to one implementation, a challenger is provided with the result of a one-way function of a secret held by a prover device. An interactive proof is employed, between the prover device and the challenger, to prove to the challenger that the secret used in the one-way function has been signed by a device signature without revealing the secret or the device signature or the prover device's identity to the challenger.

摘要： A method and system for creating random cryptographic keys in hardware is described. One or more bits are generated via one or more random bit circuits. Each random bit circuit includes a sensing device coupled to a first device and a second device to compare the first device against the second device and to generate a random bit from a random state value. The generated bits from the random bit circuits are read, and a cryptographic key may then be computed based on the generated bits.

摘要： Providing conditional access to a unique device identifier (ID) stored in a device in a processing system may be accomplished by determining if a platform state (such as firmware and/or data) is present in a non-volatile storage of the processing system; when the platform state is not present, loading the device ID into a volatile storage of the processing system, receiving a request from an external entity to obtain the device ID, sending the device ID to the external entity, and rejecting all subsequent requests to obtain the device ID; and when the platform state is present, rejecting all requests to obtain the device ID.
