The next era is foreseen to revolutionize the utility application with the technological advancements in IT and telecommunication. Intelligence will be seen in industrial machines equipped with embedded technologies enabling communication using low power wireless technology. Smart meter has recently gained lot of attention from the research community as this has raised unique challenges especially w.r.t security. Privacy preservation in such an environment is discussed to be critical as it may lead to devastating effects or even blackout which has been witnessed before. In this paper, the authors propose a privacy preserving algorithm which ensures resiliency against credentials theft with cryptographic operations where they are transported in a secure manner.
