The problem of character occurrence frequency distortion in a simple substitution cipher

Abstract:

The present paper deals with the effect of symbol frequency distortion for a simple substitution cipher based on an 'alphabet compression', using quadratic residues and nonresidues in finite fields.

Simple substition cipher, frequency analysis, quadratic residue
