Traditional ciphers like RSA, AES, etc. have proven to be slow ciphering multimedia information compared to chaos-based ones. For this reason and taking advantage of the availability of GPGPU, a chaotic image encryption algorithm has been ported to GPU using the CUDA programming framework in order to assess its performance and find out if this kind of accelerators provides a more suitable platform than the CPU for this sort of problems.
