Symmetric Twin Column Parity Mixers and Their Applications

Symmetric Twin Column Parity Mixers and Their Applications

The circulant twin column parity mixer (TCPM) is a type of mixing layer for the round function of cryptographic permutations designed by Hirch et al. at CRYPTO 2023. It has a bitwise differential branch number of 12 and a bitwise linear branch number of 4, which makes it competitive in applications...
