Cryptanalysis of A Privacy-Preserving Smart Metering Scheme Using Linkable Anonymous Credential.

Abstract

Abstract: To accomplish effective privacy protection in smart grid systems, various approaches were proposed combining information security technology with the smart grid’s new features. Diao et al. proposed a privacy-preserving scheme using linkable anonymous credential based on CL signature, and demonstrated its identity anonymity, message au-thentication and traceability of broken smart meters. In this paper, a forgery attack is presented to point out the protocol dissatisfies message authentication and unforgeability. We hold the idea that this scheme doesn’t have basic safety requirements and application value.
