Data Security Using Armstrong Numbers

In the real world, it is difficult to transmit data from one place to another with security. To ensure secured data transmission, universal technique called cryptography is used, which provides confidentiality of the transmitted data. In this paper Encryption and decryption process uses Armstrong number which is referred as a secret key. To make the Authentication between two intended users along with the security, server is used. With the help of server, both sender and receiver will get validated. Then actual data could be transmitted by any of the means.
