Propagation of communication signal is an open medium process. Various methods are proposed for securing the transmission of messages in communication process. Cryptography provides us with a specific form or key by which the corresponding person or receiver could only retrieve the message transferred. There are several encryption and decryption algorithms for encrypting the data at sending edge and decrypting the encrypted data at receiver edge ensuring the secure data communication. Decryption is the reverse process to encryption. In this paper we propose a method of encryption of any message using algebraic chess notation or chessboard mapping. © 2016, International Journal of Pharmacy and Technology. All rights reserved.
