    摘要: A method, apparatus and system for improving security on a virtual machines host is described. A shared file system on the host may include annotations usable by a service module to access files across VMs and to enforce security policies. The service module may additionally enable a unified user interface to improve usability of the host.

    摘要: In one implementation, a method for ensuring the trustworthiness of graphical user interfaces is described wherein a computing system user selects and/or modifies an image to be used as at least a portion of the background of one or more visual elements of a graphical user interface of a trusted computing environment. The user selected background image facilitates recognition by the user of the trustworthiness of the environment's graphical user interface when it is displayed to the user. The computing system seals the selected image or a modified version of the selected image within the trusted computing environment to prevent access to that image by computing environments other than the trusted computing environment. Additional embodiments are described and claimed.

    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).
