21、on COM(2007) 96 RFID in Europe: steps towards a policy framework. This Communication proposed steps which needed to be taken to reduce barriers to adoption of RFID whilst respecting the basic legal framework safeguarding fundamental values such as health, environment, data protection, privacy and se

22、curity. In December 2008, the European Commission addressed Mandate M/436 to CEN, CENELEC and ETSI in the field of ICT as applied to RFID systems. The Mandate M/436 was accepted by the ESOs in the first months of 2009. The Mandate addresses the data protection, privacy and information aspects of RFI

23、D, and is being executed in two phases. Phase 1, completed in May 2011, identified the work needed to produce a complete framework of future RFID standards. The Phase 1 results are contained in the ETSI Technical Report TR 187 020, which was published in May 2011. Phase 2 is concerned with the execu

24、tion of the standardisation work programme identified in the first phase. This Technical Report is related to the development of a Technical Specification to define the device interface to support ISO/IEC 18000-3 Mode 3 tags. The proposed Technical Specification on a device interface was intended to

25、 support two high frequency air interface protocols; ISO/IEC 18000-3 mode 1 that has been established and used for 15 years and ISO/IEC 18000-3 mode 3 that is just emerging. The assumption was that ISO/IEC 18000-3 mode 3 would offer greater security and that the protection of the privacy would be be

26、tter served by it. The proposed device interface is intended as a serious attempt to bring greater control to this highly used air interface protocol. In addition, by developing a device interface that supports both air interface protocols, there is the potential to assist in the migration from the

27、older, and (suggested) less secure, technology to a newer and (assumed) more robust technology. Robustness, in this case, is not only of benefit to the operator of the system but also to end users who come into daily contact with the technologies. In the exploration phase to start with the preparati

28、ons for the Technical Specification the project team encountered a challenge to translate the specifics of the required device interface features into practical specifications. First it was not clear why ISO/IEC 18000-3 mode 3 would offer greater security to protect the privacy of the consumers. Sec

29、ond it was not obvious to which “application” the reader should connect and how the proposed device interface would contribute to improving the privacy protection of the consumer. Therefore the project team decided to consult the industry to get their feedback on the proposed standard for a device i

30、nterface. The device interface is aimed at supporting ISO/IEC 18000-3 technology. The Library industry is by far the largest market for the ISO/IEC 18000-3 tags. Therefore this Technical Report will focus on the value that the proposed device could offer to improve the protection of the privacy of t

31、he consumer of the European Library Industry. This Technical Report describes the project teams approach to resolve the challenges. Clause 6 described the evaluation of the privacy protection level of 18000-3 Mode 3. Clause 7 describes the feedback of the industry on the need for the device interfac

32、e. Clause 8 describes the feedback of the industry on features of the device interface as listed in the scope. Clause 9 points to some potential threats caused by some of the memory content in library RFID tags. Annex A contains the list of industry representatives who have contributed to the creati

33、on of this report. Clause 5 draws the conclusions. PD CEN/TR 16669:2014 CEN/TR 16669:2014 (E) 6 1 Scope The scope of this Technical Report is to assess the need to develop a Technical Specification to define an interface that provides RFID system control components with low-level access to RFID inte

40、ection of the consumers privacy. The differences between ISO/IEC 18000-3 Mode 1 and Mode 3 are on the physical layer and on the memory addressing. Mode 3 in comparison to Mode 1 does not provide any additional feature that could be used to improve consumer privacy. The device interface will not help

41、 to improve the privacy protection of the European citizen. The feedback from the representatives of the European Library Industry in Clause 7 makes clear that the industry sees neither an advantage nor a need for the proposed standard for it will not improve the privacy protection of the citizen in

42、 any way. Besides the fact that the proposed standard will not help to improve the privacy protection of the citizen, the cost of developing and implementing such interface in the existing infrastructure of the RFID Application Software or Library Management Systems would be prohibitive. Therefore C

43、EN/TC 225 Project Team E recommends dropping the development of the proposed device interface standard. 6 Evaluation privacy protection level of ISO/IEC 18000-3 Mode 3 6.1 General The description of Deliverable Task E.4 states: There is one event that might completely change the situation: the intro

44、duction of ISO/IEC 18000-3 Mode 3 air interface protocol and tags. This technology is still in its infancy, but has been developed as the high frequency equivalent of the ISO/IEC 18000-6 Type C technology. It offers higher performance, greater security, and the attributes of medium range reading tha

45、t has proved acceptable for many applications. As examples ISO/IEC 18000-3 Mode 3 offers three features not supported by the established high frequency RFID tags: 1) the technology does not depend on a persistent tag id for air interface communications; 2) it supports standardized access passwords;

46、3) it supports a kill function. This is remarkable, because key difference of ISO/IEC 18000-3 Mode 3 versus ISO/IEC 18000-3 Mode 1 is the speed of reading so that more items could be scanned per second. Mode 3 does not offer any more features that can be used to protect the privacy of the consumer.

47、This clause describes the evaluation if the assumed security features. PD CEN/TR 16669:2014 CEN/TR 16669:2014 (E) 8 6.2 Technology does not depend on a persistent tag id for air interface communications ISO/IEC 18000-3 Mode 1 and ISO/IEC 18000-3 Mode 3 have a different way of collision resolution, b

48、ut in both case the end result is a constant reply that always returns the same number for the tag. Mode 1 tags always return the UID, Mode 3 tags always return the UII. Figure 1 illustrates the interaction between an interrogator and a tag for mode 3 tags. Figure 1 Interaction between interrogator

49、and tag While the UII could be empty for the purpose of the anti-collision the TID memory is defined to contain unique information, where read access cannot be prevented. 6.3 Support of standardized access passwords 6.3.1 ISO/IEC 18000-3 Mode 3 tags ISO/IEC 18000-3 Mode 3 tags do support passwords, but they have no relevance for the protection of the consumers privacy. The memory of a Mode 3 tag is logically separated into four distinct banks, as shown in Figure 2. Figure 2 Memory map of ISO/IEC 18000-3 mode 3 tags PD CEN/T
