Abstract
The present invention discloses a bus monitor for enhancing SOC system security and a realization method thereof. The bus monitor disposed between a system bus and a system control unit includes a configuration unit, a condition judgment unit, an effective data selection unit, a hardware algorithm unit and a comparative output unit. Without affecting the bus access efficiency, the present invention provides the method capable of immediately monitoring the bus behavior, and the detection system notices whether a particular bus access serial behavior is changed due to an accidental fault or intentional attacking fault. If the particular bus access serial behavior is changed, the present invention warns the system to adopt a suitable security measure to prevent the security hidden trouble and leakage of classified information due to the incorrect system security process.
