Sufficient variables for transition function of a modified additive generator
We consider the class of bijective shift registers of length n over the set Vr of binary vectors of length r. In this paper, we research registers constructed on the additive generators modulo 2 modified by a transformation of Vr. The feedback function of such a register is a composition of additive generator feedback function and the transformation of Vr. It is known that determination of sufficient variables for the composition of nonlinear functions is a complicated problem. By using combinative properties of the bijection Z2r о Vr, we describe the set of all sufficient variables for feedback function of the registers researched.
