Now a days sensitive information are progressively utilized as a part of correspondence over the web. A security of information is greatest concern of web clients. Best arrangement is utilization of some cryptography calculation which scrambles information in some figure and exchanges it over web and again unscrambled to unique information. RBG encryption provides solution to datasecurity problem using Rail fence technique, binary to grey code conversion, ASCII value and Diffie–Hellman key exchange algorithm. It takes plain text as input and apply rail fence technique then covert it into ASCII value. After that change text to binary and from binary to grey code. Take a key to apply encryption with the help of EX-OR operation and Diffie-Hellman key exchange algorithm to transfer key from sender to receiver. This key will be useful to decrypt the message.Generating a DH key is relatively cheap compare to RSA. In RSA, we need to find two large primes. It’s very expensive to generate a new RSA key-pair for each connection. The proposed RBG encryption takes less encryption time compared to RSA,DES and less CPU overhead also. © 2016, International Journal of Pharmacy and Technology. All rights reserved.
