Experiment of SPA Attack Against RSA
Chen Kai-yan · Computers & Security · 2009
Explains the relation of the power consumption characters and data-dependent power consumption of CMOS logic gates which form the integrated circuits (ICs). A RSA cipher system was implemented with an AT89C52 SCM, and with this expriment platform, a power trace of RSA encryption was obtained. It gets the power trace of a RSA encryption algorithm through the physical experiment, and directly gets the key with the SPA. The result indicates that attacking RSA encrypted systems without some extra protective measures SPA is quite easy and efficient.
