Criterion of Correlation Immunity for k-Dimension p~r-Valued Logic Functions
Yaqun Zhao · Journal of Information Engineering University · 2007
Combining the p-adic decomposition of the variables in Zpr,this paper mainly discusses the correlation immunity of k-dimension pr-valued logic functions.The decomposable properties and equivalent description of pr-valued random vector are presented.Then the p-adic decomposition of both k-dimension pr-valued logic functions and the variables are given.And then a linear combining theorem and a spectrum criterion of correlation immunity of k-dimension pr-valued logic functions are shown by using generalized Chrestenson cycle spectrum directly.
