Generation of Variable Session Keys Based on Piggybacking Strategy

Since the dawn of computer networks, protecting information from unauthorized users becomes like a battle field for the researchers and the attackers. Whenever any new solutions have been designed by the researchers to achieve the confidentiality and integrity towards the shared information, a new problem is always arisen by the attackers who are always ready to find out the loopholes. One of the solutions is to achieve and make difficult for the attacker by changing the keys frequently during the message transmission. In this regard, Automatic Variable Key (AVK) is an alternative approach to fulfill the requirements of such key variations. Therefore, in this article we have analyzed such approaches and given the contributions by proposing a new method to generate the keys which can enhance the security issues by increasing the randomness among the set of auto generated keys.
