Enhanced Security by Modifying Playfair Cipher
Abstract: Cryptography is the way and research of concealing information. It is basically a mathematical way to keep information safe and unthreatened. Nowadays, storage systems are increasingly subject to attacks. So, cryptography is a means of security and protection from harm. Cryptography is achieved by using various ciphers, in this paper we have studied the playfair cipher and have generated a comparison in timings of bruteforce attack on a normal playfair versus a modified playfair.
Keywords: Cipher, Playfair Cipher, Substitution Cipher, Cryptography
