Abstract

Abstract: As such various cryptanalytic attacks become stronger day by day, attaining the security over a single key based techniques become a complicated and burning problem among the researchers. Even, in the session key approaches, when session extends for a little bit longer, protecting data in ciphertext only attack also cannot be assured. In this regard, various mechanisms have been proposed to change the key frequently by establishing the session keys in every short interval. But, such schemes may not be suitable and survive for real time applications because of unnecessary increase of network overheads and enhancement of costs exponentially. So, to tackle such problems, we have proposed a true random key variation technique based on piggybacking strategies and one time pad (OTP) under public key environments.
