Generating Variable Keys in Automatic Variable Key with Noise Burst Bit in Cryptography towards Data Transfer for Achieving Perfect Security

One technique, named as AVK, we can create keys from data to data or session to session that is known as dynamic key. Using this type of technique we can overcome the problem that arises with a static key. The same key has been used for the entire data communication in case of static key and if anyhow it has been compromised then the basic requirement of cryptography fails. In these proposed techniques, few dynamic key generation techniques have been generated and the variable keys have been generated based on some existing techniques namely, CSAVK, ASAVK, LSAVK and KVRN by incorporating noise burst bit. From the performance analysis, we have been observed that the auto generated keys are more random in the proposed techniques. The randomness of successive generated keys has been tested with the help of National Institute of Standards and Technology (NIST) which is a statistical tool and proved that the generated keys are truly random. Finally, we have concluded that these techniques can be used in real-time applications as they provide more security as compared to other existing schemes.
