On advanced cryptographic techniques for information security of smart grid AMI

Abstract

This paper provides a discussion of certain cryptographic issues regarding the development of advanced and dedicated cryptographic techniques for providing information security of Smart Grid Advanced Metering Infrastructure (AMI). We point out to three frameworks with potential to provide highly secure and implementation low complexity primitives for developing AMI dedicated cryptographic techniques which minimizes the overhead implied by the security requirements. The addressed frameworks are related to the techniques for symmetric encryption, authentication and secret keys management. We focus on the primitives for authentication and encryption based on joint employment of pseudorandomness, randomness and dedicated coding, and secret keys management based on the broadcast encryption paradigm.
