摘要
A system security breach detection method and a breach detector capable of detecting external breach and responding to the breach are provided to guarantee an excellent reliability with a small calculation amount by a mode using parity comparing to a encryption module based on security processor. A parity memory(708) stores the instruction relationship information and parity relationship information. An instruction correlation inspector(704) determines correlation through the verification through the parity check mode about the instructions and instruction relationship information. According to the correlation, the instruction correlation inspector detects the outside breach. In case an unexpected problem is occurred at an operating system, the security processor checks the state in terms of hardware and includes interrupt(714) corresponding to change.
