## H2020-MSCA-RISE-MIXMAX

Action title:

Development and Implementation of new generation of Pseudo Random Number
Generator MIXMAX

based on Anosov-Kolmogorov C-K systems

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No 644121.
