Abstract
Method for detecting the linear extraction of information in a processor using an instruction register for storing an instruction including an operation code. The method includes monitoring the instructions successively stored in the instruction register including decoding the operation codes, determining the number of consecutive operation codes encoding incremental branches, and generating a detection signal if the number is greater than or equal to a detection threshold.
