Abstract: The role of cryptography in today’s world is increasing day by day. Information is flowing from one place to another on the network. One most common cryptography technique is substitution cipher. Play fair is most common substitution cipher. In this paper, we present an overview of existing playfair ciphers. Encryption/decryption is a very popular task. We also explain the fundamentals of sequential cryptography. We describe today’s approaches for play fair cipher. Their strengths and weaknesses are also investigated. It turns out that the behavior of the algorithms is much more similar as to be expected.
Keywords: Cryptography, Network Security, Symmetric Key, Play fair cipher and substitution.
