摘要： In accordance with certain aspects, data is received from a calling program. Ciphertext that includes the data is generated, using a symmetric cipher, in a manner that allows only one or more target programs to be able to obtain the data from the ciphertext. In accordance with other aspects, a bit string is received from a calling program. An identifier of the calling program is checked to determine whether the calling program is allowed to access data encrypted in ciphertext of the bit string. The integrity of the data is also verified, and the data is decrypted using a symmetric key. The data is returned to the calling program only if the calling program is allowed to access the data and if the integrity of the data is successfully verified.

摘要： Mechanisms are disclosed that may allow certain memory access control algorithms to be implemented efficiently. When memory access control is based on controlling changes to an address translation map (or set of maps), it may be necessary to determine whether a particular map change would allow memory to be accessed in an impermissible way. Certain data about the map may be cached in order to allow the determination to be made more efficiently than performing an evaluation of the entire map.

摘要： To render digital content encrypted according to a content key (KD) on a first device having a public key (PU1) and a corresponding private key (PR1), a digital license corresponding to the content is obtained, where the digital license includes the content key (KD) therein in an encrypted form. The encrypted content key (KD) from the digital license is decrypted to produce the content key (KD), and the public key (PU1) of the first device is obtained therefrom. The content key (KD) is then encrypted according to the public key (PU1) of the first device (PU1 (KD)), and a sub-license corresponding to and based on the obtained license is composed, where the sub-license includes (PU1 (KD)). The composed sub-license is then transferred to the first device.

摘要： To obtain a digital license for rendering a piece of digital content, a license requester contacts a license provider and sends a license request. The license provider checks the license request for validity and negotiates with the license requestor terms and conditions for the requested license. The license provider generates the requested license and issues the generated license to the license requestor.

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.

摘要： Theft of decompressed digital content as the content is being rendered is prevented. A requested slow-down of the rendering of the content is detected. Transfers of relatively large amounts of data are detected. A re-compressor-based requested slow-down of the rendering of the content is detected. A re-compressor re-compressing the content is detected. In each situation, the detected activity is presumably initiated by a content thief attempting to steal the content. In each situation, the detected activity is responded to in a manner designed to frustrate the presumed attempt of the content thief to steal the content.

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.
