PROCESSOR INSTRUCTION CHECK METHOD DURING PROGRAM EXECUTION

摘要

A processor instruction check method during program execution, mainly comprising the following contents: before program execution, calculating an address of each correct instruction in all the code segments of a program, then converting the address of the correct instruction into address check data, and finally, in the program execution process, when a processor calculates a branch target address of a branch transfer instruction and does not submit a result, checking the calculated branch target address. The method can be used for stopping a malicious code constructed by using an abnormal instruction sequence of a program from being executed on a processor.
