Data Security Using Triple Encryption

In the present work the author has suggested a unique cryptographic method where by using transposition and rotation ciphers, triple encryption (E³) is achieved. In this method, E³ is achieved by first applying the transposition cipher on the plain text and then applying rotation cipher on this transposed text. The proposed method can be applied to encrypt any data consisting of 30 or more characters. The results obtained after application of proposed algorithm are excellent and difficult to decrypt.
