Abstract:

Several generalized methods of constructing partially-bent functions are presented. Meanwhile the Walsh cyclic spectrum characteristics of these partially-bent functions are shown.In addition,the method of constructing partially-bent functions with more variables by bent functions with less variables.

Key words: Bent function, partially-Bent, function Walsh cyclic spectrum, auto-correlation function
