An Efficient Cryptographic Scheme for Text Message Protection Against Brute Force and Cryptanalytic Attacks

Security is the biggest concern for any information transferred in the world of Internet. Sometimes sensitive information is communicated via insecure medium so various attacks like Brute force, Crypt analytic are possible for recovering message and key. In recent years, encryption technology has been developed very quickly to secure the transmitted information. Existing techniques have separate mechanism for key distribution and for encryption and decryption at source and destination. As per our best knowledge there is no algorithm that is implemented till now that generates the key and then encrypts the message with that key then transfers the message and the key securely so that the same key can be used for decrypting the message. Still the cipher text remains that of original message length. In this paper we have proposed an efficient cryptographic scheme for text message protection against Brute force and Cryptanalytic attacks. This technique can also be used for most crucial applications where it requires a significant security of transmitted message and also there is no overhead on the transfer of message and the key when it is used with our proposed technique.
