Implementation of AES with Handshake Protocol against Differential Power Analysis

This paper presents the field programmable gate array (FPGA) implementation of the Advanced Encryption Standard (AES) with handshake protocol to resistant differential power analysis (DPA). DPA is a powerful side-channel analysis (SCA) attack. A SCA attack takes advantage of implementation specific characteristics to recover the secret parameters involved in the computation. We propose a DPA-resistant design method with handshake protocol to make the power traces misaligned. AES algorithm was implemented in Xilinx Spartan III-E FPGA device using the structure of handshake protocol. At last, an experiment platform was built to prove that the design has ability to resistant the differential power analysis.
