1. A method of providing for resistance to attack of an integrated circuit by means of monitoring current changes in a current signal in the integrated circuit, said method comprising the step of including as part of said integrated circuit a spurious electromagnetic noise generation circuit for emitting electromagnetic noise and reducing a Signal to Noise Ratio to obscure information in the current signal that is meaningful for the attack.
