Abstract :
Refresh techniques can greatly enhance security and privacy of Class-1 Generation-2 RFID tags (Gen2 tags), without requiring any cryptographic capabilities from the tags. We propose a refresh-based RFID system and define a notion of privacy for the system. Privacy analysis investigates a novel security property of public-key encryption schemes, which plays the fundamental role to satisfy the defined privacy requirement. While conventional refresh-based solutions only help enhance privacy, the proposed solution also provides the limited authentication.
