Offloading Secure Hash Algorithm (SHA) on GPU

Graphical Applications are becoming very attractive because of their Interactive Graphical User Interface, but it requires more computational power. GPU (Graphical Processing Unit) is used for running these graphical applications. Today Graphical Processing Unit (GPU) is having high computational power and memory bandwidth. Graphical applications are using GPU’s computational power for improving their Performance. (E.g. Scientific and Medical applications) Other general purpose application also can use this computational power. This Paper explains about improving the performance of Secure Hash Algorithm (SHA) using GPU. This implementation improves the speed of computation in some of the stages of SHA algorithm and shows the result and effectiveness of the GPU as compared to the CPU implementations.
