A novel authentication protocol enabling RFID tags ownership transfer

摘要: Ownership of RFID tag may be frequently changed during its lifetime, thus how to securely transfer ownership between owners is very important. Recently, some lightweight cryptograph-based authentication protocols have been proposed resolve the problem, but most them assume that channel reader and database server secure, ignore backward un-traceability. Hence operations, there exist inevitably security/privacy vulnerabilities exposed malicious users previous owner. In this paper, we propose a novel protocol enabling tags transfer. Based on challenge-response mechanism, achieves mutual database. Moreover, it provides prevent fake reader. Also, based BAN logic give proof correctness. The merit our not only well protects owner's privacy also high-security high-efficiency.
