MICROPROCESSOR SYSTEM WITH INFORMATION PROTECTION AGAINST READING BY CONSUMED CURRENT

摘要

Micro-processor system with information protection against reading by current consumption includes computer module that is connected to power supply source, variable capacitor that is connected to power supply source and control circuit, control circuit connected to variable capacitor and to power source. Additionally it includes noise generator that is connected to control circuit, at that frequency of current generator exceeds timing frequency pf computing module.
