摘要： A resource is obtained from a resource provider (RP) for a resource requester (RR) operating on a computing device. The RR has an identity descriptor (id) associated therewith, where the id including security-related information specifying an environment in which the RR operates. A code identity (code-ID) is calculated corresponding to and based on the loaded RR and loaded id. The RP verifies that the calculated code-ID in a request for the resource matches one of one or more valid code-IDs for the identified RR to conclude that the RR and id can be trusted, and the RP responds to the forwarded request by providing the requested resource to the RR.

摘要： A mechanism for protected operating system boot that prevents rogue components from being loaded with the operating system, and thus prevents divulgence of the system key under inappropriate circumstances. After a portion of the machine startup procedure has occurred, the operating system loader is run, the loader is validated, and a correct machine state is either verified to exist and/or created. Once the loader has been verified to be a legitimate loader, and the machine state under which it is running is verified to be correct, the loader's future behavior is known to protect against the loading of rogue components that could cause divulgence of the system key. With the loader's behavior being known to be safe for the system key, the validator may unseal the system key and provides it to the loader.

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： 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： Systems and methods provide multiple partitions hosted on an isolation technology such as a hypervisor where at least one of the partitions, a local secure service partition (LSSP), provides security services to other partitions. The service partitions (LSSPs) host those high assurance services that require strict security isolation, where the service can be shared across partitions and accessed even when the user is not connected to a network. The LSSP also can certify the results of any computation using a key signed by a TPM attestation identity key (AIK), or other key held securely by the hypervisor or a service partition. The LSSPs may be configured to provide trusted audit logs, trusted security scans, trusted cryptographic services, trusted compilation and testing, trusted logon services, and the like.

摘要： To authenticate a program on a computing device to a resource local to or remote from the computing device, a stored program security identifier (PSID) corresponding to the program is retrieved, where the stored PSID includes information taking into account the program itself, the execution setting of the program, and any inputs and initializations that are provided to the program. The PSID is re-constructed based on the same information as obtained from local sources, and the stored and reconstructed PSIDs are compared to determine whether a match exists. If so, it may be concluded that the program operates in a trusted manner according to an approved set of conditions.

摘要： At computer device power on, the operating system of the computer device initiates a monitor. The monitor assigns a monitoring program to each program and object (collectively, “program”) running on the computer device to monitor the activities of the program. When the monitoring program is assigned to a program, the monitoring program is assigned an integrity and/or privacy label (collectively, “integrity label”) based on predetermined criteria applied to the monitored program. The monitoring program, in turn, assigns an integrity label to the program monitored by the monitoring program. The integrity label assigned to the monitored program is less than or equal to the integrity label of the monitoring program. The monitor enforces an integrity policy of the computer device based on the integrity label assigned to monitored programs and the integrity label associated with data, another program, or a remote network resource that the monitored program is seeking to access.

摘要： Systems and methods that establish a secured compartment that manages sensitive user transactions/information on a user's machine. The secured compartment qualifies user interaction with the machine, and separates such qualified interaction from other user activity on the machine. A user is switched to such secured compartment upon occurrence of a predetermined event, such as in form of: an explicit request (e.g., a secure attention sequence); an implicit request (e.g., inference of user activities); and presence of a peripheral device that is bound to the secured compartment (e.g., a USB)—wherein such actions typically cannot be generated by an application running outside the secured compartment.
