Benefit from the novel compute unified device architecture (CUDA) introduced by NVIDIA, graphics processing unit (GPU) turns out to be a promising solution for cryptography applications. In this paper we present an efficient implementation for MD5-RC4 encryption using NVIDIA GPU with novel CUDA programming framework. The MD5-RC4 encryption algorithm was implemented on NVIDIA GeForce 9800GTX GPU. The performance of our solution is compared with the implementation running on an AMD Sempron Processor LE-1200 CPU. The results show that our GPU-based implementation exhibits a performance gain of about 3-5 times speedup for the MD5-RC4 encryption algorithm.
