Vectorization on ChaCha Stream Cipher [PDF]
2014 11th International Conference on Information Technology: New Generations, 2014 This paper describes software optimization for the stream Cipher ChaCha. We leverage the wide vectorization capabilities of the new AVX2 architecture, to speed up ChaCha encryption (and decryption) on the latest x86_64 processors. In addition, we show how to apply vectorization for the future AVX512 architecture, and get further speedup.

, 2021 We propose the ChaCha (Champion-Challengers) algorithm for making an online choice of hyperparameters in online learning settings. ChaCha handles the process of determining a champion and scheduling a set of `live' challengers over time based on sample complexity bounds. It is guaranteed to have sublinear regret after the optimal configuration is added
