Efficient AES implementations on ASICs and FPGAs

Abstract

In this article, we present two AES hardware architectures: one for ASICs and one for FPGAs. Both architectures utilize the similarities of encryption and decryption to provide a high throughput using only a relatively small area. The presented architectures can be used in a wide range of applications. The architecture for ASIC implementations is suited for full-custom as well as for semi-custom design flows. The architecture for the FPGA implementation does not require on-chip block RAMs and can therefore even be used for low-cost FPGAs. © Springer-Verlag Berlin Heidelberg 2005.
