The minimum distance between Bent functions and Resilient functions is studied.An algorithm for calculating the minimum distance between Bent functions and resilient functions is given.We give a new lower bound for the minimum distance between Bent functions and 1-resilient functions.This new lower bound is better than that presented by S.Maity etc in 2004
and their conjectures are proven to be true.The minimum distances between Bent functions and 1-resilient functions on 12 and 14 variables are also given.
