摘要

In this paper, we present an anonymous authentication scheme that allows RFID tags to authenticate to readers without dis-closing the tag identity or any other information that allows tags to be traced. The properties of our scheme are very useful for a variety of ac-cess control systems, where it is sufficient or mandatory to verify the authenticity of a tag without inferring its identity.rnOur scheme is based on the recently proposed anoymizer-approach, where additional devices (called anonymizers) frequently interact with the tags to ensure anonymity and unlinkability of tags. This allows using cost-effective RFID tags that cannot perform public-key cryptography in an efficient and scalable way. Our solution provides (i) anonymity and untra-cability of tags against readers, (ii) secure tag authentication even against collusions of malicious readers and anonymizers, and (iii) security against denial-of-service attacks.
