Implementation and optimization of high speed AES algorithm based on GPGPU and CUDA

Compared with the CPU which is good at handling logic complexity service,GPGPU(general purpose graphic processing unit) is suitable for large-scale parallel processing computing.The emergence of CUDA(compute unified device architecture) accelerates the expansion of application of GPGPU.We accelerate the implementation of AES algorithm based on GPGPU and CUDA and achieve a total throughput of 6~7Gbit/s.Regardless of the time of data loading and storing,a throughput of 20Gbit/s towards an input size over 1MB can be achieved.
