Fast Software AES Encryption

This paper presents new software speed records for AES-128 encryption for architectures at both ends of the performance spectrum. On the one side we target the low-end 8-bit AVR microcontrollers and 32-bit ARM microprocessors, while on the other side of the spectrum we consider the high-performing Cell broadband engine and NVIDIA graphics processing units (GPUs). Platform specific techniques are detailed, explaining how the software speed records on these architectures are obtained. Additionally, this paper presents the first AES decryption implementation for GPU architectures. Key words: Advanced Encryption Standard (AES), Advanced Virtual RISC (AVR), Advanced RISC Machine (ARM), Cell Broadband Engine, Graphics Processing Unit (GPU), Symmetric Cryptography
