Abstract
Method for detecting the linear extraction of information in a processor using an instruction pointer. The method includes monitoring the values of the instruction pointer, determining a number of consecutive increments incrementing the values of the instruction pointer by a constant amount, and generating a detection signal if the number is greater than or equal to a detection threshold.
