PGMAP: a privacy guaranteed mutual authentication protocol conforming to EPC class 1 gen 2 standards

摘要

To resolve the security vulnerabilities and comply with EPC Class 1 Gen 2 UHF RFID (EPC C1G2) Standard at the same time, we present a Privacy Guaranteed Mutual Authentication Protocol (PGMAP). By utilizing the existing functions and memory bank of tag, we amend the processing sequence based on current EPC architecture. An auto-updating index number IDS is enrolled to provide privacy protection to EPC code and a set of light weight algorithms utilizing tag's PRNG are added for authentication. Several attacks to the existing security solutions can be effectively resolved in our protocol. © 2008 IEEE.
