The Analysis and Research about a Mask Design of AES
Guo Shun Wang, Yan Zhang · Advanced materials research · 2012
AES encryption system is briefly introduced, the function and principle of mask technology has been expressed. Because the vulnerability of the AES encryption system by the energy attacks, the measures need to add to increase the ability of energy analysis of AES. The mask design content is added in the AES encryption system. The mask design of AES encryption was given detailed. Four steps of the mask design process are also given. The conversions and implementation of AES mask design are presented, such as, the transformation of S box and so on. The implementation methods of how to eliminate the mask are given in the final round of AES encryption. It is finally discussed that threaten and influence of energy attack on AES.
