Abstract

Abstract:

In recent years,technologies of smart grid have developed rapidly. As one of the basic devices for data collection in smart grid, smart meter has problems of insufficient authentication and user privacy leakage. A secured authentication scheme using Physical Unclonable Function（PUF）, MAC-then-Encrypt（MtE） and one-way Hash Function is proposed . In the security analysis, the improved BAN logic is used in formal analysis. The results show that this scheme can resist physical attacks, smart meter internal attacks, man-in-the-middle attacks,etc., and ensure the confidentiality and integrity of the transmitted data.

Key words: smart meter, authentication, physical unclonable function, physical attack, one-way Hash Function, security
