Design of high speed advanced encryption standard (AES) encryption circuit

Abstract

With the fast development of Internet network to share information and communicate from all over the world, the security of the information has become imperative. In order to meet the demand of encoding a huge amount of data, this thesis introduced a high-speed 128-bit AES encryption circuit. The main contribution of this thesis is to state two kinds of AES circuit design. It investigated and designed the architecture and analyzed the rtl code of each kind of AES circuit. By comparing the post-synthesis simulation of two AES circuits, the optimized circuit improves the throughput effectively. The proposed optimized high-speed 128-bit AES encryption circuit has a throughput about 5 times higher than the standard design.
