The process of exchanging information is called Communication. The basic Communication system involves


transmitter, receiver and the channel. The data transmitted by the sender reaches receiver through the


channel. The unauthorized parties (cracker,hacker, eavesdropper, or attacker) should not be able to access


the information at the channel. Therefore transmitting data securely from the sender to the receiver is a very


important aspect. A cryptographic system is unconditionally secure if the cipher text produced by the system


does not contain enough information to determine uniquely the corresponding plaintext, no matter how much


cipher text is available. A cryptographic system is said to be computationally secure if the cost of breaking the


cipher exceeds the value of the encrypted information and the time required to break the cipher exceeds the


useful lifetime of the content. One time pad system can be called as unconditionally secure algorithm, if the


keys (pad) usedare truly random in nature. In this paper, we are demonstrating that one-time pad can be used


as an efficient encryption scheme by involving arithmetic and logical operations. Here we proposed a new key


generation technique, to generate a key of any length just by providing a seed value, to encrypt the message.


The problem generating key value has been solved by the use of key generation algorithm.
