21、D 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 security. In December

22、 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 RFID, and is being exe

23、cuted 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 execution of the standar

24、disation 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 support two high f

25、requency 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 better served by it.

26、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 older, and (suggest

27、ed) 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 preparations for the Technic

28、al 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. Second it was not obvi

29、ous 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 interface. The devic

30、e 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 the consumer of the

31、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 interface. Clause 8 describ

32、es 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 creation of this report.

33、Clause 5 draws the conclusions. PD CEN/TR 16669:2014CEN/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 interrogators for the pu

34、rpose of optimising RFID data access and control operations. 2 Normative references Not applicable. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 air interface complete communication link between an Interrogator and a Tag including the phys

40、 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 to improve the privacy

41、 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 any way. Besides the f

42、act 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 CEN/TC 225 Project Team

43、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 introduction of ISO/IEC 1800

44、0-3 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 that has proved acceptable

45、 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; 3) it supports a kill f

46、unction. 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. This clause describes t

47、he evaluation if the assumed security features. PD CEN/TR 16669:2014CEN/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, but in both case the end

48、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 and tag While the UII co

49、uld 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/TR 16669:2014CEN/TR 16669:2
