An Improved AES Masking Method Smartcard Implementation for Resisting DPA Attacks
Currently, side-channel analysis has become a hotspot of cryptographic analyses. Different from conventional cryptographic security analyses, side-channel analyses monitors the changes in the electronic features of the IC, and exploit the information leakage with side channel characteristics (E.g. Power and EM). With modern statistics, now engineers and attackers are able to reveal sensitive data with side channel analyses. Side-channel analysis, especially the power analysis attacks, on software or hardware implementations of various crypto-systems aim at recovering the secret key information from power consumption performed on the smart card.
