摘要： To render digital content determined to be in an encrypted rights-protected form, each available license corresponding to the digital content to be rendered is identified, where each such license includes a decryption key (KD) for decrypting the digital content to be rendered, and where the decryption key (KD) in the license is encrypted according to a public key (PU) (PU(KD)). One of the identified licenses is selected and (KD) is obtained from the selected license by obtaining (PU(KD)) from the selected license and decrypting (PU(KD)) according to a private key (PR) corresponding to (PU) to produce (KD). The digital content is decrypted with (KD), and the decrypted digital content is provided for actual rendering.

摘要： A digital rights management system for the distribution, protection and use of electronic content. The system includes a client architecture which receives content, where the content is preferably protected by encryption and may include a license and individualization features. Content is protected at several levels, including: no protection; source-sealed; individually-sealed (or “inscribed”); source-signed; and fully-individualized (or “owner exclusive”). The client also includes and/or receives components which permit the access and protection of the encrypted content, as well as components that allow content to be provided to the client in a form that is individualized for the client. In some cases, access to the content will be governed by a rights construct defined in the license bound to the content. The client components include an object which accesses encrypted content, an object that parses the license and enforces the rights in the license, an object which obtains protection software and data that is individualized for the client and/or the persona operating the client, and a script of instructions that provides individualization information to a distributor of content so that the content may be individualized for the client and/or its operating persona. Content is generally protected by encrypting it with a key and then sealing the key into the content in a way that binds it to the meta-data associated with the content. In some instances, the key may also be encrypted in such a way as to be accessible only by the use of individualized protection software installed on the client, thereby binding use of the content to a particular client or set of clients.

摘要： A system and method for performing a scan of an input sequence in a parallel processor having a shared register file. A two dimensional matrix is generated, having a number of rows representing a number of threads and a number of columns based on the input sequence block size and the number of rows. One or more padding columns may be added to the matrix to avoid or reduce memory bank conflicts. A first traversal of the rows performs a reduction or a scan of each of the rows in parallel, storing the reduction values. The reduction values are used during a second traversal to propagate the reduction values. In a segmented scan, propagation is selectively performed based on flags representing segment boundaries.
摘要翻译：一种用于在具有共享寄存器文件的并行处理器中执行对输入序列的扫描的系统和方法。生成二维矩阵，其具有表示线程数量的多行和基于输入序列块大小和行数的列数。可以将一个或多个填充列添加到矩阵中以避免或减少存储体冲突。行的第一次遍历对并行的每行进行缩小或扫描，存储缩小值。在第二次遍历期间使用缩小值来传播缩小值。在分段扫描中，基于表示段边界的标志选择性地执行传播。

摘要： An access control policy engine associated with a resource determines whether to allow a request to access same. The engine receives the request with an security token, retrieves the token determines a type thereof, and maps access decision information in the token to a common format as at least one security claim setting forth adequate information to determine a right of the requestor. Thereafter, the engine retrieves a set of rules for accessing the resource, applies the rules to the security claims to determine whether to allow the request from the requestor, and if the request is to be allowed, provides the requestor access to the resource in accordance with the request and the rights of the requestor as determined based on the security claims.

摘要： In order to allow for security beyond revocation lists, a policy regarding when permissions may be granted (in the form of a rights document, e.g. a use license or a certificate) is enforced. When a request is made for a rights document, the requester submits an account certificate which includes certain metadata regarding the requester. This metadata is analyzed to determine whether it meets a specific policy before the request is granted. If the request is not granted, the cause of the rejection may be overcome, for example by updating or upgrading some system component (hardware or software) in the requesting system. In certain cases, such an update to overcome a policy-based rejection may be performed transparently to the user.
摘要翻译：为了允许超出撤销列表的安全性，执行关于何时可以授予权限（以权利文档的形式，例如使用许可证或证书）的策略。当为权利文件提出请求时，请求者提交一个帐户证书，其中包括有关请求者的某些元数据。分析此元数据以确定在批准请求之前是否满足特定策略。如果不允许请求，则可以克服拒绝的原因，例如通过更新或升级请求系统中的一些系统组件（硬件或软件）。在某些情况下，可以透明地对用户执行这种克服基于策略的拒绝的更新。
