Abstract
A system and method for securing processing devices includes a police bridge disposed in one or more data busses between a central processing and input/output peripherals, components or components. The police bridge is suitably disposed between northbridge logic and southbridge logic. Alternatively, or in addition to such placement, a police bridge is suitably place between southbridge logic and super I/O logic. A police bridge is suitably a system-on-chip or fixed or programmable hardware. The police bridge monitors or controls its associated bus to determine whether acceptable data, with an associated certificate in other embodiments, is being communicated and signaling is generated accordingly.
