Abstract

The theme of our research is to provide security for the data that contains alphanumeric values during its transmission. The best known multiple letter encryption cipher is the play fair, which treats the plain text as single units and translates these units into cipher text. It is highly difficult to the intruder to understand or to decrypt the cipher text. In this we discussed about the existing play fair algorithm, its merits and demerits. The existing play fair algorithm is based on the use of a 5 X 5 matrix of letters constructed using a keyword. This algorithm can only allow the text that contains alphabets only. For this we have proposed an enhancement to the existing algorithm, that a 6 X 6 matrix can be constructed.
