Uni-variate polynomial

[dibyendu...@gmail.com]

Hi can anyone help me in the following code.

From the following code I am getting ANF from g. But I want to get g function (univariate polynomial) from the given ANF of Boolean function. How to get it?

R.<x>=GF(2^8,'a')[]

from sage.crypto.boolean_function import BooleanFunction

g=x^254

B = BooleanFunction( g )

print(B)

print(B.algebraic_normal_form())
