A Reliable Secret Key Algorithm for Encryption and Decryption of Text Data
Publication Date : 26/02/2016
Cryptography converts the original message into non-readable format andsends the message over an insecure channel.Classical cryptanalysis involves an interestingcombination of analytical reasoning andmathematical tools. Several algorithms have been developed and used complicated keys to produce cipher text from plain text or complicated algorithms for it. Security of all algorithms is dependent on length of keys and techniques used in the algorithm. In this paper we proposed an efficient reliable symmetric key based algorithm to encrypt and decrypt the text data. We use ASCII (8 bit) value of alphabet and perform some simple calculation like logical NOT and binary division to produce. The proposed method is easy to understand and easy to implement.
