Abstract
In this investigation, we have generalized and modified the Playfair cipher into a block cipher. Here, we have introduced substitution, interweaving and iteration. The cryptanalysis and the avalanche effect carried out in this analysis markedly indicate that the cipher is a strong one, and it cannot be broken by any cryptanalytic attack.
Keywords
