    摘要: Secure storage and retrieval of a unique value associated with a device to/from a memory of a processing system. In at least one embodiment, the device needs to be able to access the unique value across processing system resets, and the device does not have sufficient non-volatile storage to store the unique value itself. Instead, the unique value is stored in the processing system memory in such a way that the stored unique value does not create a unique identifier for the processing system or the device. A pseudo-randomly or randomly generated initialization vector may be used to vary an encrypted data structure used to store the unique value in the memory.

    摘要: Delivering a Direct Proof private key to a device installed in a client computer system in the field may be accomplished in a secure manner without requiring significant non-volatile storage in the device. A unique pseudo-random value is generated and stored in the device at manufacturing time. The pseudo-random value is used to generate a symmetric key for encrypting a data structure holding a Direct Proof private key and a private key digest associated with the device. The resulting-encrypted data structure is stored on a removable storage medium (such as a CD), and distributed to the owner of the client computer system. When the device is initialized on the client computer system, the system checks if a localized encrypted data structure is present in the system. If not, the system obtains the associated encrypted data structure from the removable storage medium. The device decrypts the encrypted data structure using a symmetric key regenerated from its stored pseudo-random value to obtain the Direct Proof private key. If the private key is valid, it may be used for subsequent authentication processing by the device in the client computer system.

A unique pseudo-random value is generated and stored in the device at manufacturing time. The pseudo-random value is used to generate a symmetric key for encrypting a data structure holding a Direct Proof private key and a private key digest associated with the device. The resulting encrypted data structure is stored on a protected on-liner server accessible by the client computer system. When the device is initialized on the client computer system, the system checks if a localized encrypted data structure is present in the system. If not, the system obtains the associated encrypted data structure from the protected on-line server using a secure protocol. The device decrypts the encrypted data structure using a symmetric key regenerated from its stored pseudo-random value to obtain the Direct Proof private key. If the private key is valid, it may be used for subsequent authentication processing by the device in the client computer system.

    摘要: Delivering a Direct Proof private key in a signed group of keys to a device installed in a client computer system in the field may be accomplished in a secure manner without requiring significant non-volatile storage in the device. A unique pseudo-random value is generated and stored along with a group number in the device at manufacturing time. The pseudo-random value is used to generate a symmetric key for encrypting a data structure holding a Direct Proof private key and a private key digest associated with the device. The resulting encrypted data structure is stored in a signed group of keys (e.g., a signed group record) on a removable storage medium (such as a CD or DVD), and distributed to the owner of the client computer system. When the device is initialized on the client computer system, the system checks if a localized encrypted data structure is present in the system. If not, the system obtains the associated signed group record of encrypted data structures from the removable storage medium, and verifies the signed group record. The device decrypts the encrypted data structure using a symmetric key regenerated from its stored pseudo-random value to obtain the Direct Proof private key, when the group record is valid. If the private key is valid, it may be used for subsequent authentication processing by the device in the client computer system.

    摘要: Managing authorization tokens within a computer system may be accomplished by creating a master owner token indicating full ownership of a resource within the computer system by a management environment, creating at least one delegate owner token for a environment, communicating the delegate owner token to the environment and to the resource, and allowing access to the resource by the environment when the environment presents a valid delegate owner token to the resource. In one embodiment, the resource comprises a trusted platform module (TPM).

    摘要: Methods and apparatus for mixing encrypted data with unencrypted data are disclosed. A disclosed system receives data from a first media source, such as DVD-Audio content, and encrypts the data from the first media source using a key stream to form an encrypted data stream. The disclosed system may separate the encrypted data stream into a plurality of encrypted data streams and may combine the plurality of encrypted data streams with an unencrypted data stream associated with a second media source to form a mixed data stream. The mixed data stream is formed without decrypting the plurality of encrypted data streams and is transmitted to hardware or a hardware driver.

    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.
