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.

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 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： 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： 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： In one embodiment, a method of remote attestation for a special mode of operation. The method comprises storing an audit log within protected memory of a platform. The audit log is a listing of data representing each of a plurality of IsoX software modules loaded into the platform. The audit log is retrieved from the protected memory in response to receiving a remote attestation request from a remotely located platform. Then, the retrieved audit log is digitally signed to produce a digital signature for transfer to the remotely located platform.

摘要： A system and method for secure distribution of a video card public key. The method provides for loading an authentication code module into a processor, authenticating the authentication code module, and executing the authentication code module. Executing the authentication module causes the authentication code module to assert a hardware indicator to access at least one address in a special protected page on a chipset. Receipt of the hardware indicator by the chipset causes a specific reference to be sent via a dedicated port to a circuit card to retrieve a public key from the circuit card.
