Abstract: In an embodiment, a method for protecting an electronic circuit includes: detecting a malfunction of the electronic circuit; executing a plurality of waves of countermeasures without interrupting an operation of the electronic circuit; and triggering a reset of the electronic circuit after executing the plurality of waves of countermeasures. An interval between two waves of countermeasures of the plurality of waves of countermeasures is variable.

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.

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.
