EPPAS: Energy‐efficient privacy‐preserving and physically secure mutual authentication scheme for secure communication in smart grid systems

Abstract

Summary Electricity generation, transmission, distribution, and consumption are efficiently monitored and controlled by the next‐generation power grid called a smart grid systems (SGs) with the help of information and communication technology (ICT). Due to this ICT intervention, the SGs are facing a lot of security threats. The main security threats are tampering of smart meters and meter data because they are fixed in the customer places without any hardware security. This may result in inaccurate billing and wrong decisions related to grid management. To overcome these issues, an energy‐efficient privacy‐preserving and physically secure mutual authentication scheme is proposed for providing secure communication in SGs by using the one‐way hash functions, bitwise exclusive‐OR operations, physically unclonable functions (PUFs), and reverse fuzzy extractor. The security and performance analysis section ensures that the proposed scheme provides essential security features with less computation and communication overhead compared to that of other existing schemes. Therefore, it is better suitable for resource‐limited SGs.

Certificateless Network Coding Ring Signature Scheme

“…A CL-NCRS can meet the unconditional anonymity [18][19][20]: no attacker can obtain the private key of all possible signers in illegal ways. For the adversary, since a j (j ≠ s and a j ≠ 1) is randomly chosen from Z * q , then the probability of selecting a 1 , a 2 , .…”
