Cryptanalysis of the acbf encryption system

The ACBF encryption system with a functional key is considered. A public key in the cryptosystem is a vectorial Boolean function f in n variables obtained by permutation and negation operations on variables and coordinate functions of a bijective vectorial Boolean function g, that is, f (x) = n2(g°"2(n1(xCT1))), n1,n2 £ Sn and а1,а2 £ Fn are key parameters. A private key is f-i. For two subsets of key parameters, namely for {n1} and {n1,n2}, attacks with known plaintexts are proposed.
