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： 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： 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： 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： 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： 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： 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： A single application can be executed across multiple execution environments in an efficient manner if at least a relevant portion of the virtual memory assigned to the application was equally accessible by each of the multiple execution environments. A request by a process in one execution environment can, thereby, be directed to an operating system, or other core software, in another execution environment and can be made by a shadow of the requesting process in the same manner as the original request was made by the requesting process itself. Because of the memory invariance between the execution environments, the results of the request will be equally accessible to the original requesting process even though the underlying software that responded to the request may be executing in a different execution environment. A similar thread invariance can be maintained to provide for accurate translation of requests between execution environments.

摘要翻译： 如果分配给应用的虚拟存储器的至少相关部分可以被多个执行环境中的每个执行环境同等地访问，则可以以有效的方式在多个执行环境中执行单个应用。 一个执行环境中的进程的请求可以由此被引导到另一执行环境中的操作系统或其他核心软件，并且可以以与原始请求相同的方式通过请求进程的阴影来进行 通过请求过程本身。 由于执行环境之间的内存不变性，即使响应请求的底层软件可能在不同的执行环境中执行，原始请求进程的请求结果也可以同样访问。 可以维护类似的线程不变性，以便在执行环境之间提供精确的请求转换。
