AES block cipher implementations with AMBA-AHB interface

Abstract

The aim of this work is to describe three different architectural designs for AES cipher, which is a symmetric block encryption standard. The three architectures are oriented to different applications and are designed using different approaches, like pipeline structures and resource sharing. They also include an AMBA AHB interface, which is an open standard that defines the interconnection of blocks in a System-on-Chip (SoC).
