Boosting differential-linear cryptanalysis of ChaCha7 with MILP by Bellini, Emanuele, Gerault, David, Grados, Juan, Makarim, Rusydi H., Peyrin, Thomas

“…We eventually obtain a new distinguisher for ChaCha reduced to 7 rounds that requires 2166.89 computations, improving the previous record (ASIACRYPT 2022) by a factor of 247. Also, we obtain a distinguisher for ChaCha reduced to 7.5 rounds that requires 2251.4 computations, being the first time of a distinguisher against ChaCha reduced to 7.5 rounds. …”
