Bhagyashree Bodkhe, D. C. Jain

Abstract


Cryptography mechanisms deal with encoding the data into unintelligent information rather than hiding it. In aspect of
Information Security, Cryptography is one of the conventional used techniques for secure communication. The goal of this
research is to find the efficient and most widely used cryptographic algorithm which is best suitable for play-fair.

Keywords
