Abstract:

Presents a method to combine resilient functions over a Galois ring by a quasi-affine function to get a new resilient function of higher resilient order.From the discussion of the construction of quasi-affine functions, it is seen that there are abundant choices of quasi-affine functions.

Key words: resilient function, Galois ring, combination of function, quasi-affine function CLC TP309
