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： A data storage resource is identifiable by physical addresses, and optionally by a virtual address. A policy defines which resources are accessible and which resources are not accessible. A request to access a resource is allowed if access to the resource is permitted by the policy, and if carrying out the access will not cause virtual addresses to be assigned to resources to which the policy disallows access. Since resources to which access is disallowed do not have virtual addresses, certain types of access requests that identify a resource by a virtual address can be allowed without consulting the policy.

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.
摘要翻译：根据某些方面，从呼叫程序接收数据。使用对称密码，以允许只有一个或多个目标程序能够从密文获得数据的方式生成包含数据的密文。根据其他方面，从呼叫程序接收到位串。检查调用程序的标识符以确定是否允许调用程序访问以位串的密文加密的数据。还验证数据的完整性，并使用对称密钥对数据进行解密。只有当主叫程序被允许访问数据并且数据的完整性被成功验证时，才将数据返回给调用程序。

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： Encrypted compressed content is produced by encrypting content based at least in part on a content key, and compressing the content based at least in part on the content key. Thus, the content key is employed to encrypt the content and also to compress the content. Similarly, decrypted decompressed content is produced from the encrypted compressed content by decrypting the content based at least in part on a content key, and decompressing the content based at least in part on the content key. Thus, the content key is employed to decrypt the content and also to decompress the content.

摘要： Operating system upgrades in a trusted operating system environment allow a current trusted core of an operating system installed on a computing device to be upgraded to a new trusted core. The new trusted core is allowed to access application data previously securely stored by the current trusted core only if it can be verified that the new trusted core is the new trusted core expected by the current trusted core. In accordance with one implementation, the new trusted core is allowed to access only selected application data previously securely stored by the current trusted core.

摘要： A digital rights management (DRM) system operates on a computing device and requires a black box for performing decryption and encryption functions. To obtain the black box from a black box server, the DRM system requests such black box from such black box server. The black box server in response generates the black box, where such black box is unique and has a public/private key pair. The black box server then delivers the generated black box to the DRM system and the DRM system installs the delivered black box in such DRM system.
