9. N-RFID Security

10. Security Session of ITU-T N-RFID workshop (Jan. 2006. Geneva) • Three presentations for security session • Security Issues in RFID and Sensor Networks, Kyo-Il Chung, ETRI, Korea • Authentication and privacy capabilities suitable for RFID capabilities suitable for RFID, M. Robshaw, France Telecom R&D, France • Malicious Traceability within RFID Systems, Gildas Avoine, EPFL, Lausanne, Switzerland

11. Observations of Workshop(1/2) • Light weight security protocol should be developed to provide the confidentiality, anonymity, un-traceability and forgery protection to counter all types of threats in network-based RFID. • The dedicated techniques may be well-suited to RFID tags and offer a safe foundation. • Preventing from malicious traceability should be provided for privacy protection of RFID, especially for the passport application. • However, key management and scalability are identified to be very challenging problems to be explored.

12. Observations of Workshop(2/2) • Some standardization items identified : • Security framework for RFID: • NGN Security architecture for network aspects of identification (including RFID) services and applications; • Various authentication protocol including password access protocol to lock or kill an RFID tag for privacy control; • Privacy management framework and protocol based on a user profile; • Adult confirmation technology; • Protocol for countering malicious traceability; • Secure data exchange protocol for application.

13. Conclusions

14. Necessity of Security Activities under CJK IT meeting • The security will become a mandatory function, not an optional function. That is, the security should be integrated into every level of NGN: access network level, transport stratum, and service stratum. • Seamless service for NGN can only be possible with the aid of security. • The security on networked RFID become very important to make the N-RFID service feasible in the near future. • We, CJK, are now leading the standardization activities for NGN, especially in SG13 and SG17 in ITU-T. Indeed, 22 out of 35 recommendations are being developed by editors from CJK for SG17.

15. How to collaborate? • Therefore, collaboration between CJK is very important to accelerate the standardization work for global work like ITU-T. • ITU-T has coordinated structure for security on NGN; the security framework has been assigned to SG13, and detailed security mechanisms and protocols to SG17. • Considering the spirit of coordination on the security in ITU-T, how do we collaborate with each other efficiently under CJK IT Standards group? • To make new working group to cover a security-related issues focusing on NGN and N-RFID under the CJK group in the near future.

16. Security WG under CJK IT Plenary • Build CJK Security Working Group • Scope of new Security Working Group • Collaborate with NGN WG + N-RFID WG + B3G WG on security isseus. • In addition, ISMS, Secure application protocol, Home network security is addressed. • ToR of CJK Security Working Group • Encouraging members’ activity on Security standards • Collaboration for global standard activity: SGs and FG in ITU-T • Development of CJK requirements and contributions • Sharing information and experiences

17. Structure of Security WG • Structure of Security WG with other WG CJK PL. Coordination Coordination NGN WG Security WG N-RFID WG Management (1CH+2VC) Strategy SC Drafting SC Drafting SC

18. How do we work efficiently? • Work method • Use CJK plenary meeting for face-to-face meeting. • Use preparatory coordination meeting before ITU-T meeting. • Use e-mail reflectors to discuss a specific issues. This presentation was supported by the MIC, Korea, under the ITRC support program supervised by the IITA. (IITA-2005-(C1090-0502-0020))
