Symmetric key cryptography on modern graphics hardware

Abstract

GPUs offer a tremendous amount of computational bandwidth that was until now largely unusable for cryptographic computations due to a lack of integer arithmetic and user-friendly programming APIs that provided direct access to the GPU's computing resources. The latest generation of GPUs, which introduces integer/binary arithmetic, has been leveraged to create several implementations of the AES and DES symmetric key algorithms. Both conventional and bitsliced implementations are described that achieve data rates on the order of 3-30 Gbps from a single AMD HD 2900 XT graphics card, yielding speedups of 6-60× over equivalent implementations on high-performance CPUs. © International Association for Cryptology Research 2007.
