Secure Hardware Implementation of ARIA Based on Adaptive Random Masking Technique
The block cipher ARIA has been threatened by side-channel analysis, and much research on countermeasures of this attack has also been produced. However, studies on countermeasures of ARIA are focused on software implementation, and there are no reports about hardware designs and their performance evaluation. Therefore, this paper presents an advanced masking algorithm which is strong against Second-Order Differential Power Analysis (SODPA) and implements a secure ARIA hardware. As there is no comparable report, the proposed masking algorithm used in the hardware module is evaluated using a comparison result of software implementations.
