General purpose graphics processing units in security
The use of multiple computers that work together towards delivering a common goal is one way of tackling computationally expensive problems that otherwise require a very long time, but nowadays general purpose graphics processing units (GPGPUs) are emerging as a novel way of speeding up the performance of computers in solving complex algorithmic problems resulting in very good speedups. An interesting idea which has been proven to yield important speedups in practice, is to utilize this newly found resource for security purposes such as hash collisions, cryptographic operations and other such parallelizable security-related tasks. We will present the results of our research into the commodity GPU market, the speedup we obtained on certain computer forensics tasks, and the various pitfalls that fellow researchers may encounter if attempting to utilize GPGPU architectures,such as the NVidia named Compute Unified Device Architecture (CUDA).
