摘要： To determine whether digital content can be released to an element such as a computer application or module, a scaled value representative of the relative security of the element is associated therewith, and the digital content has a corresponding digital license setting forth a security requirement. The security requirement is obtained from the digital license and the scaled value is obtained from the element, and the scaled value of the element is compared to the security requirement of the digital license to determine whether the scaled value satisfies the security requirement. The digital content is not released to the element if the scaled value does not satisfy the security requirement.

摘要： A digital rights management (DRM) system operates on a computing device when a user requests that a protected piece of digital content be rendered by the computer device in a particular manner. The DRM system has a license store, a license evaluator, and a state store. The license store stores digital licenses on the computing device. The license evaluator determines whether any licenses stored in the license store correspond to the requested digital content and whether any such corresponding licenses are valid, reviews license rules in each such valid license, and determining based on such reviewed license rules whether such license enables the requesting user to render the requested digital content in the manner sought. The state store maintains state information corresponding to each license in the license store, where the state information is created and updated by the license evaluator as necessary.

摘要： In accordance with certain aspects, data is received from a calling program. Ciphertext that includes the data is generated, using public key encryption, in a manner that allows the data to be obtained from the ciphertext only if one or more conditions are satisfied. In accordance with another aspect, a bit string is received from a calling program. Data in the bit string is decrypted using public key decryption and returned to the calling program only if one or more conditions included in the bit string are satisfied.

摘要： In accordance with certain aspects, data is received and a digital signature is generated and output. The digital signature can be a digital signature of the data and one or more conditions that are to be satisfied in order for the data to be revealed, or a digital signature over data generated using a private key associated with a bound key that is bound to one or more processors.

摘要： Plural guest operating systems run on a computer, where a security kernel enforces a policy of isolation among the guest operating systems. An exclusion vector defines a set of pages that cannot be accessed by direct memory access (DMA) devices. The security kernel enforces an isolation policy by causing certain pages to be excluded from direct access. Thus, device drivers in guest operating systems are permitted to control DMA devices directly without virtualization of those devices, while each guest is prevented from using DMA devices to access pages that the guest is not permitted to access under the policy.

摘要： The various embodiments described below are directed to providing authenticated and confidential messaging from software executing on a host (e.g. a secure software application or security kernel) to and from I/O devices operating on a USB bus. The embodiments can protect against attacks that are levied by software executing on a host computer. In some embodiments, a secure functional component or module is provided and can use encryption techniques to provide protection against observation and manipulation of USB data. In other embodiments, USB data can be protected through techniques that do not utilized (or are not required to utilize) encryption techniques. In accordance with these embodiments, USB devices can be designated as “secure” and, hence, data sent over the USB to and from such designated devices can be provided into protected memory. Memory indirection techniques can be utilized to ensure that data to and from secure devices is protected.
摘要翻译：下面描述的各种实施例旨在从在USB总线上操作的I / O设备到主机（例如安全软件应用或安全内核）上执行的软件提供经认证和保密的消息传递。这些实施例可以防止在主计算机上执行的软件所征收的攻击。在一些实施例中，提供了安全的功能部件或模块，并且可以使用加密技术来提供对USB数据的观察和操纵的保护。在其他实施例中，USB数据可以通过不被利用（或不需要利用）加密技术的技术来保护。根据这些实施例，USB设备可以被指定为“安全”，因此，可以通过USB向这些指定设备发送和从这些指定设备发送的数据提供到受保护的存储器中。可以利用内存间接技术来确保进出安全设备的数据受到保护。

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.
