Cheating immune secret sharing in the unconditionally secure case are investigated in this paper.Constructionsof defining functions of cheating immune secret sharing on V_n are given,where n is any integer greater than 5.Further-more,the obtained defining functions have good cryptographic properties.The nonlinearity of them is 2~(n-1)-2~(n/2+1) whenn≡0(mod 4)and 2~(n-1)-2~((?)n/2」+2) otherwise.And thedegree is「n/4(?).
