METHOD AND DEVICE FOR THE DETECTION OF ERROR JUMPS DURING THE EXECUTION OF A PROGRAM

摘要

The invention relates to a method by which a processor (IC1) executes a program read in a program memory (MEM1), comprising the following steps: detection of a program memory read address jump; prior to a program memory read address jump instruction, prediction of an instruction for the storage of the presence of the address jump instruction; and activation of an error signal (ERR) if an address jump has been detected and if the presence of an address jump instruction has not been stored. The invention can be used to secure integrated circuits.
