    摘要: An electronic device, such as, a computer, may be adapted for self-monitoring for compliance to an operating policy. The operating policy may specify a pay-per-use or subscription business model and measurements associated with compliant usage. A secure execution environment may measure usage in accordance with the business model as well as monitor and enforce compliance to the operating policy. To increase the difficulty of attacking or otherwise disabling the secure execution environment, elements of the secure execution environment may be distributed. The distribution points may include other functional elements of the computer, such as interface circuits, or may even be remotely located over a network. An implementation method for disaggregating the secure execution environment is also disclosed.

    摘要: Described is an independent computation environment that is built into one or more hardware components of a computer system, wherein the independent computation environment hosts a logic that measures the health of other software code that executes in memory. Examples of ways to measure health include performing a mathematical computation such as a computing a hash/digital signature on the software code in the memory, and/or evaluating statistical information related to the execution of the code and/or the code's being loaded into memory. By executing the logic in an independent computation environment, the health of software code may be measured against policy/metadata in a tamper-proof or tamper-resistant environment. When the software code measurement does not comply with the policy, some action may be taken action to penalize the computer system.

    摘要: Described is a technology by which a computing device is booted into a normal mode of operation or a limited mode of operation, depending on whether the computing device was operating correctly (e.g., with respect to policy) prior to a reboot. The reboot may be forced. Examples of incorrect state include an overdue payment on a leased computer, or improper execution of certain important software. A metering mechanism evaluates the state of the computing device, and when an incorrect state is detected, configures the computing device for operation in the limited mode, by setting the computing device to boot via one boot path (e.g., a limited-mode BIOS) instead of another boot path (e.g., a normal-mode BIOS). A BIOS selector switches to the limited BIOS on the next reboot, wherein the computing device is restricted to the limited mode of operation (regardless of subsequent reboots) until the correct state is restored.

    摘要: A virtual machine monitor provides a trusted operating environment for a software usage metering application when a qualified virtual machine monitor is loaded as part of trusted boot and when all other programs and operating systems run in containers managed by the virtual machine monitor. The virtual machine monitor may also host a locking application for limiting the functionality of the computer if contractual terms of use are not met. Both the metering and locking applications run at a higher privilege level than ring 0, at the same level as the virtual machine monitor.
