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.
