Comparison of old and new cryptographic hash function standards of the Russian Federation on CPUs and NVIDIA GPUs

We present optimization guidelines and implementations of cryptographic hash functions GOST R 34.11-94 and GOST R 34.11-2012. Results for x86_64 CPUs and NVIDIA CUDA-capable GPUs are provided for our and several other well-known implementations. It is shown that the new standard may be twice as fast as the old one on modern CPUs, but it may be slower on embedded devices and GPUs. The results given for our implementation are the fastest among all the tested implementations on both platforms.
