DPA Resistant AES Using a True Random Based LFSR Technique

Reenu Tomy | Vinoj P.G. ^[2]

Abstract: Advanced Encryption Standard (AES) is an algorithm which is used to protect data, which uses cipher key in order to protect the data block. However this is vulnerable to Differential Power Attack (DPA). In order to protect AES from DPA attack we can use masked AES technique, which is implemented in this paper. In first order masked AES we are removing the correlation between the intermediate result and the secret key. One of the main drawback of this method is large area consumption. We can alleviate this problem by introducing randomness in to it by using LFSR. The comparison between both the architectures are made on the basis of the power rating estimated using Xilinx ISE tool.
