Privacy issues Guideline for Disaster recovery and emergence telecommunication service RFID security issues through NGN

The 6th CJK IT Standards Meeting 9 N-RFID Security

The 6th CJK IT Standards Meeting 10 Security Session of ITU-T N-RFID workshop (Jan 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

The 6th CJK IT Standards Meeting 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.

The 6th CJK IT Standards Meeting 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.

The 6th CJK IT Standards Meeting 13 Conclusions

The 6th CJK IT Standards Meeting 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.

The 6th CJK IT Standards Meeting 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.

The 6th CJK IT Standards Meeting 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

The 6th CJK IT Standards Meeting 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 reflectors to discuss a specific issues. This presentation was supported by the MIC, Korea, under the ITRC support program supervised by the IITA. (IITA (C ))
