摘要： A system and method for maintaining persistent data during an unexpected power loss uses a memory controller and a supplemental power source. An entity running on the computer, for example, an application program, a utility, the operating system or other entity, may identify data for preservation using an application program interface. The application program interface may be provided by the memory controller. A sensor determines when an unexpected power loss has occurred and signals the memory controller. Using power from the supplemental power source, i.e. a battery or capacitor, the memory controller copies the identified data to a non-volatile memory. The memory controller may set a flag to indicate that preserved data is available for later recovery.

摘要： A network security system for protecting computing devices connected to a communication network from identified security threats is presented. A security service published security information intended for network security modules in the communication network. A network security module is interposed, either logically or physically, between a computer and the communication network. The security information comprises security measures which, when implemented by a network security module, protect the corresponding computer from an identified security threat to the computer.

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： Techniques are described which provide an independent computation environment. The independent computation environment is contained at least in part in a set of one or more hardware components and configured to host a provisioning module that is executable to provision functionality of the computing device according to a wide variety of factors. In an implementation, when the provisioning module determines that particular functionality is referenced in an inclusion list, the computing device is permitted to access the particular functionality. When the provisioning module determines that the particular functionality is referenced in an exclusion list, the computing device is prevented from accessing the particular functionality.

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.

摘要： A pay-per-use computer, or other electronic device that uses local security, may use a security module or other circuit for monitoring and enforcement of a usage policy. To help prevent physical attacks on the security module, or the circuit board near the security module, a second circuit may be mounted over the security module to help prevent access to the security module. Both circuits may be mounted on a interposer and the interposer mounted to the circuit board, creating a stack including the first circuit, the interposer, the security module, and a main PC board. When the PC board includes dense signal traces under the security module a three dimensional envelope is created around the security module. When the first circuit is a high value circuit, such as a Northbridge, the risk/reward of attacking the security module is increased substantially and may deter all but the most determined hackers.

摘要： A computer is adapted for use in different operating modes by configuring an output controller, such as a graphics processing unit, to screen output signals prior to presenting them to the output device. A secure environment in the output controller verifies a digital signature or a hash of the output signal to determine whether the output signal is compatible with the current mode of operation. Thus only authorized output signals are presented when the computer is operating in a limited function mode, such as when metered usage time is expired. The apparatus and method also disclose similar output signal screening for determining whether the computer should be returned from a standby, or no-metering, mode to an active, or metered mode.

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： A security module for a pay-per-use computer supplies an appropriate BIOS for a given mode of operation. A power manager in the security module powers only essential circuits until the BIOS is operational to help prevent substitution of a non-authorized BIOS. The security module also includes a capability to monitor and restrict data lines on a bus between a main computer processor and computer system memory. When the computer is operating in a restricted use mode, data lines may be restricted to allow only minimal access to the computer system memory. Bus transactions may be monitored to ensure that only valid transactions are occurring and are within the designated memory space.
