Secure EPCglobal Class-1 Gen-2 RFID system against security and privacy problems

Radio Frequency Identification (RFID) system is an important technology in ubiquitous computing environment. RFID system should be compatible with most RFID system applications to support the ubiquitous computing environment. Recently, researchers had studied about RFID standardization. After all, EPCglobal Class-1 Gen-2 (C1G2) RFID is selected as an international standard of RFID systems. Unfortunately, it has fatal security problems to be vulnerable to information leakage and traceability since a tag of EPCglobal C1G2 emits its fixed ID(EPC) without hiding or modifying. A main goal of our work is to propose the secure protocol well suitable for EPCglobal C1G2. First of all, our protocol exactly follows RFID standard with only current capabilities of a tag approved in the standard, assuring that our protocol is secure against impersonation, information leakage, and traceability etc.
