New AES software speed records

Daniel J. Bernstein and Peter Schwabe

Abstract: This paper presents new speed records for AES software,taking advantage of (1) architecture-dependent reduction of instructions used to compute AES and (2) microarchitecture-dependent reduction of cycles used for those instructions. A wide variety of common CPU architectures---amd64, ppc32, sparcv9, and x86---are discussed in detail, along with several specific microarchitectures.
