Abstract

Sender and receiver both uses two large similar prime numbers and uses parametric equations for swapping values of kx and by product of kx and ky is the common secret key. Generated secret key is used for encryption and decryption using ASCII key matrix of order 16X16. Applying playfair rules for encryption and decryption. Playfair is a digraph substitution cipher. Playfair makes use of pairs of letters for encryption and decryption. This application makes use of all ASCII characters which makes brute force attack impossible.
