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-line server accessible by the client computer system.

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.

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.

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.

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： 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： An apparatus and method for unilaterally loading a secure operating system within a multiprocessor environment are described. The method includes disregarding a received load secure region instruction when a currently active load secure region operation is detected. Otherwise, a memory protection element is directed, in response to the received load secure region instruction, to form a secure memory environment. Once directed, unauthorized read/write access to one or more protected memory regions are prohibited. Finally, a cryptographic hash value of the one or more protected memory regions is stored within a digest information repository as a secure software identification value. Once stored, outside agents may request access to a digitally signed software identification value in order to establish security verification of secure software within the secure memory environment.
