According to the original NESSIE submission of Whirlpool: "The ﬁnite ﬁeld ${\rm GF}(2^8)$ will be represented as ${\rm GF}(2)[x]/p(x)$, where $p(x) =$ $x^8 +$ $x^4 +$ $x^3 +$ $x^2 +$ $1$ is the ﬁrst primitive polynomial of degree $8$ listed in [19]. The polynomial $p(x)$ was chosen so that $g(x) = x$ is a generator of ${\rm GF}(2^8) \setminus \{0\}$." ...
