摘要：

A method and system for a countermeasure to power analysis attacks, where an impedance element is coupled to a power source providing power to a cryptographic module causing a measurable power supply noise, a timing sequence is generated, and the impedance element is decoupled from the power source based on the timing sequence to cause the measurable power supply noise to vary according to the timing sequence.
