Instructions Analysis for Crypto Chip Based on Power Consumption Leakage
Zou Cheng · Journal of Chinese Computer Systems · 2011
There are different power consumption leakage characters for different instructions executed in chips,and the power consumption characters can be considered as the finger printing of each instruction.Taking the idea of reverse engineering,the power traces obtained from microcontroller where instructions were executed are analyzed with Side-Channel Attacks(SCA),power consumption template(finger printing) for each instruction were constructed.Then power traces obtained from an unknown microcontroller would be recognized with these side channel templates.The side channel template analysis against the instructions executed in a microcontroller(AT89C52) validated the effective of the instructions reversing.This research exploits a new application approach of SCA.
