Parallel AES Encryption Engine for Many Core Processor Arrays Using Masked S-Box

Abstract

With the ever increasing growth of data communication, hardware encryption technology will become an irreplaceable safety technology. In this paper, I present a method of AES encryption and decryption algorithm with 128 bit key on an FPGA. In order to protect “data-at-rest” in memory from differential power analysis attacks with high-throughput advanced encryption standard (AES) engine with masked S-Box is proposed. By exploring different granularities of data-level and task-level parallelism, we map 2 implementations of an Advanced Encryption Standard (AES) cipher with online key expansion on a fine-grained many-core system.
