    摘要： Methods and systems are provided for authenticating component(s) in connection with the use of a trusted graphics system. Techniques are provided for authenticating a graphics card in connection with a system that cryptographically secures content routed through a graphics pipeline, such that an application or device can indicate to the trusted graphics platform that the application or device is a trusted user of the trusted graphics platform, and such that the graphics platform can communicate to the trusted application or device that the graphics platform may be trusted by the application or device.

    摘要： Digital content is released to a rendering application for forwarding by such rendering application to an ultimate destination by way of a path therebetween. The path is defined by at least one module, and the digital content is initially in an encrypted form. An authentication of at least a portion of the path is performed to determine whether each defining module thereof is to be trusted to appropriately handle the digital content passing therethrough. The encrypted digital content is decrypted if in fact each such defining module is to be trusted, and the decrypted digital content is forwarded to the rendering application for further forwarding to the ultimate destination by way of the authenticated path.

    摘要： A plurality of access units may be established with varying levels of privilege and access rights, such that the user may perform tasks carrying with them a high risk of viral infection in an access unit with a low level of privilege and access rights. When an authenticated user desires to perform tasks requiring a higher level of privilege and access rights, the user may switch to an access unit having a higher privilege and access rights level by instigating a physical action. The physical action may include selecting a button (included in either a UI or on a peripheral device), or inputting biometric data to switch among running access units. A signal instigated by the physical action is transmitted along a trusted path between the isolation kernel and where the physical action was instigated.

    摘要： Digital content is rendered on a device by transferring the content to the device and obtaining a digital license corresponding to the content. A sub-license corresponding to and based on the obtained license is composed and transferred to the device, and the content is rendered on the device only in accordance with the terms of the sub-license. The content is encrypted and decryptable according to a content key, and the sub-license includes the content key encrypted and decryptable according to a secret. The sub-license also includes indexing information identifying the secret to the device. The indexing information in the sub-license is obtained to identify the secret, and the secret is acquired based at least in part on the indexing information. The secret is then applied to the encrypted content key to decrypt and obtain the content key, and the obtained content key is applied to the encrypted content to decrypt and obtain the content. To compose the sub-license and also to render the content, the secret is derived by obtaining a device identifier, acquiring a super-secret, and applying the obtained device identifier and super-secret to a function to derive the secret.

    摘要： An enforcement architecture and method for implementing digital rights management are disclosed. Digital content is distributed from a content server to a computing device of a user and received, and an attempt is made to render the digital content by way of a rendering application. The rendering application invokes a Digital Rights Management (DRM) system, and such DRM system determines whether a right to render the digital content in the manner sought exists based on any digital license stored in the computing device and corresponding to the digital content. If the right does not exist, a digital license that provides such right and that corresponds to the digital content is requested from a license server, and the license server issues the digital license to the DRM system. The computing device receives the issued digital license and stores the received digital license thereon.
