3D visual method for logic functions on exhaustive sequences

Logic functions to generate pseudo-random sequence play an important role in cryptography applications. In practical security applications, in addition to time complexity, random characteristics of sequences can be investigated on spatial characteristics of logical function to test pseudo-random sequences. This paper uses a multi-parameter measurement system on three-dimension map to display spatial characteristics of logic functions. Under different coding schemes, intrinsic properties and the overall symmetry of logical functions for spatial characteristics can be observed.
