Fields

M: usize

Security level.

t: usize

Width of desired hash function, e.g. $t=3$ corresponds to a 2-to-1 hash.

alpha: Alpha

Exponent of the Sbox, i.e. S-box(x) = x^{\alpha} used in the SubWords step

rounds: RoundNumbers

Round numbers

m_e: SquareMatrix<F>

External matrix

m_i: SquareMatrix<F>

Internal matrix

arc: ArcMatrix<F>

Round constants
