SMART CARD METHOD FOR PROTECTING A SMART CARD

A method for protecting an electronic entity such as a smart card, against simple/differential power analysis, by integrating a current accumulator in said entity. The current accumulator ( 19 ) powers a processor (P) via a multiplexer ( 20 ) when the processor is loaded to execute so-called sensiti...

Zusammenfassung:	A method for protecting an electronic entity such as a smart card, against simple/differential power analysis, by integrating a current accumulator in said entity. The current accumulator ( 19 ) powers a processor (P) via a multiplexer ( 20 ) when the processor is loaded to execute so-called sensitive operations.
