摘要： Application factoring or partitioning is used to integrate secure features into a conventional application. An application's functionality is partitioned into two sets according to whether a given action does, or does not, involve the handling of sensitive data. Separate software objects (processors) are created to perform these two sets of actions. A trusted processor handles secure data and runs in a high-assurance environment. When another processor encounters secure data, that data is sent to the trusted processor. The data is wrapped in such a way that allows it to be routed to the trusted processor, and prevents the data from being deciphered by any entity other than the trusted processor. An infrastructure is provided that wraps objects, routes them to the correct processor, and allows their integrity to be attested through a chain of trust leading back to base component that is known to be trustworthy.
摘要翻译：应用因子分解或分区用于将安全特征集成到常规应用中。应用程序的功能根据给定操作是否涉及敏感数据的处理而分为两组。创建独立的软件对象（处理器）来执行这两组操作。值得信赖的处理器处理安全数据并在高保证环境中运行。当另一个处理器遇到安全数据时，该数据被发送到可信处理器。以允许将数据路由到可信处理器的方式包装数据，并且防止数据被除可信处理器之外的任何实体解密。提供了一个基础设施，用于包装对象，将它们路由到正确的处理器，并通过一系列信任来验证其完整性，并将其引导回已知可靠的基础组件。

摘要： The present invention provides for trusted side-band communications between components in a computer system, so that use of the system bus may be avoided. Two components may be connected by means other than a bus (e.g., an infrared port, a wire, an unused pin, etc.), whereby these components may communicate without the use of the system bus. The non-bus communication channel may be referred to as “side-band.” The side-band channel may be used to communicate information that might identify the user's hardware (e.g., a public key) or other information that the user may not want to be easily intercepted by the public at large. Communication over the side-band channel may also be used to verify that the participants in a communication are within a defined positional relationship to each other.
摘要翻译：本发明提供计算机系统中的组件之间的可靠的边带通信，从而可以避免使用系统总线。两个组件可以通过除总线（例如，红外线端口，电线，未使用的引脚等）之外的方式连接，由此这些组件可以在不使用系统总线的情况下进行通信。非总线通信信道可以被称为“边带”。边带频道可以用于传达可能识别用户硬件（例如，公共密钥）的信息或用户可能不希望容易被公众容易地截获的其他信息。通过边带信道的通信也可以用于验证通信中的参与者在彼此之间的定义的位置关系内。

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： 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.

摘要： Transferring application secrets in a trusted operating system environment involves receiving a request to transfer application data from a source computing device to a destination computing device. A check is made as to whether the application data can be transferred to the destination computing device, and if so, whether the application data can be transferred under control of the user or a third party. If these checks succeed, a check is also made as to whether the destination computing device is a trustworthy device running known trustworthy software. Input is also received from the appropriate one of the user or third party to control transferring of the application data to the destination computing device. Furthermore, application data is stored on the source computing device in a manner that facilitates determining whether the application data can be transferred, and that facilitates transferring the application data if it can be transferred.

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.
摘要翻译：防止正在呈现内容的解压缩数字内容的盗窃。检测到请求的内容呈现的减慢。检测到相对大量数据的传输。检测到基于重新压缩的请求的内容呈现的减慢。检测到重新压缩内容的再压缩。在每种情况下，检测到的活动大概是由试图窃取内容的内容窃贼发起的。在每种情况下，检测到的活动都以一种旨在阻止内容窃贼窃取内容的推定尝试的方式作出回应。
