A Survey on an Enhanced Cryptographic Technique for Messages Encryption and Decryption

Darshana Patil1, Prof. P. M. Chawan2

Currently, security has become one of the important factors in our day to day life. Like banks, shops and everywhere else we require security. An attacker can use the password to access the private information. To avoid this is one of the goals of the data security. As we know that we require security in our daily life then what about the security of our security system such as our national security i.e. defense. Mainly, at the time of war the terrorists, spies or an attacker tries to leak information and capture the important information which may useful to win the war. To overcome the problem the proposed technique can be used. The plain-text is treated at the bit level for encryption/decryption which provides more security than compound and intermix characters. Moreover, the advantage of the technique is that both the algorithm uses the same key generation algorithm. Here the key is generated from the plain-text bit stream and same key is used for both encryption and decryption.
