A new distinguishing attack on reduced round ChaCha permutation
This work concentrates on differential-linear distinguishing attacks on the prominent ARX-based permutation ChaCha. Here, we significantly improve the 7-round differential-linear distinguisher for ChaCha permutation by introducing a new path of linear approximation. We first introduce a new single-b...
