The classical Vigenere system for enciphering secret messages, named after Blaise de Vigenere 1523-1596, is well-known in cryptography. While a cryptogram enciphered by this method is readily solved by cryptanalysts, using such tools as probable words, repeated patterns and frequence analysis to construct a cryptographically equivalent system, it is interesting to study equivalence of Vigenere systems from a mathematical point of view. Such a study is the purpose of the present paper.
