Study of CPA on AES chip

FAN Hai-feng,XU Jin-fu,YAN Ying-jian(Institute of Electronic Technology,PLA Information Engineering University,Zhengzhou 450004,China)  
To confirm the fact that AES chip without countermeasures is vulnerable to correlation power analysis(CPA).A method of correlation power analysis to AES chip is proposed.A correlation power analysis experiment is mounted on AES chip.With extracting critical register’s information from AES hardware architecture and adopting proper power model,this information is converted to simulated instantaneous power.The simulated instantaneous power data is correlated with the power data measured from practical measurement.Eight most significant bits of key are obtained from the experiment.The result of the experiment reveals the vulnerability of AES chip without countermeasures to CPA attack.
