Security of an RFID Based Authentication Protocol with Bitwise Operations for Supply Chain

Due to the stringent computational capabilities of low-cost RFID tags, several lightweight secure authentication protocols have been proposed for an RFID-based supply chain using bitwise operations. In this paper, we study vulnerabilities associated with operations by doing cryptanalysis a protocol tags. The like rotation and XOR show that is vulnerable tag, reader, node impersonation attacks. We find major cause vulnerability suggest physically unclonable functions rather than such protocols. provide formal analysis AVISPA tool various
