摘要： A security module may be used to verify integrity of an executable program and may also be used to verify execution of the executable program on a computer. The security module may directly read a computer memory by asserting bus master control of a system bus. The executable program may be directly verified by calculating a hash or may be indirectly verified by an intermediate program that calculates the hash and passes it to the security module. To verify operation, the executable program may cause an interrupt to be generated when the executable program is in a known state. An interrupt service routine may trigger the security module to read registers in the computer processor via a debug port. If either the verification of the executable program fails or the register values are inconsistent with operation of the executable program, the security module may interrupt operation of the computer.

摘要： A display device for use with a computer adapted for operation in an unrestricted use mode and a limited function mode and a method for enforcing a limited function mode display is disclosed. The display device enters a limited function mode when a condition of non-compliance with an operating policy is discovered by the computer. Additionally, the display device may also enter a limited function mode upon powering up or when connections to the computer and/or selected components of the display are disabled or disconnected. When in the limited function mode, the display may support a limited function interface for use in correcting the condition of non-compliance.

摘要： A computer or other electronic device requiring physical integrity of its components, for example, a pay-per-use computer may use a master security device in communication with a plurality of slave security devices, known as security beans. Each security bean may be given a cryptographic key or keys for use in authenticating communication with the master security device. Each security bean may be coupled to an associated component and may have the ability to disable that associated component. In one embodiment, security bean has an analog switch that may be configured to block or attenuate a critical signal used by the associated component. The security bean may start up in the disable mode and respond to a verified signal from the master security device to enable its corresponding component.

摘要： A security module is used to perform an audit of both a computer memory and the computer's processor status. The security module may assert itself as a bus master to read the computer memory without dependence on a program running on the computer. In addition, using a separate hardware path, the security module may access processor register data using a debug port. The security module may collect both memory and processor status information without the use of any of the computer resources being measured, avoiding either alteration of the data by the measurement tool or tampering with the data while being collected.

摘要： A security circuit in a computer monitors data busses that support memory capable of booting the computer during the computer reset/boot cycle. When activity oil one of the data busses indicates the computer is booting from a non-authorized memory location, the security circuit disrupts the computer, for example, by causing a reset. Execution from the non-authorized memory location may occur when an initial jump address at a known location, such as the top of memory, is re-programmed to a memory location having a rogue BIOS program.

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.
