Abstract: A METHOD (100) FOR GENERATING A NONLINEAR BOOLEAN PERMUTATION, THE METHOD (100) COMPRISES SELECTING N NUMBER OF INITIAL BINARY BOOLEAN FUNCTIONS FOR A FIRST N NUMBER OF COMPONENTS OF THE NONLINEAR BOOLEAN PERMUTATION (102), ITERATING CONVERTING LINEAR COMBINATION OF THE SELECTED N NUMBER OF INITIAL BINARY BOOLEAN FUNCTIONS TO A PLURALITY OF BALANCED FUNCTIONS (104), RANDOMLY GENERATING A REMAINING NUMBER OF COMPONENTS OF THE NONLINEAR BOOLEAN PERMUTATION (106) AND PERFORMING A NONLINEARITY TEST ON THE NONLINEAR BOOLEAN PERMUTATION (108) TO OBTAIN NONLINEARITY PARAMETER, UNTIL THE NONLINEARITY PARAMETER MEETS A PREDETERMINED CONDITION.
