Meet the gKrypt engine, the world's first package to employ general purpose graphics units (GPGPUs) for data encryption. It uses an Advanced Encryption Standard (AES) based 256-bit block cipher. This is the second article in a two-part series on AES encryption and the gKrypt engine. Part 1 introduced gKrypt and explained the AES algorithm in detail, its parallel breakdown and how to map it on a massive GPU architecture using the Compute Unified Device Architecture (CUDA). Part 2 looks at how AES is implemented on CUDA.
