19、2014 and EN 419212-2:2014.This standard supports services in the context of electronic IDentification, Authentication and Trust Services (eIDAS) including signatures.In EN 419212 Part 2, the standard allows support of implementations of the European legal framework for electronic signatures, definin

21、et”.A Secure Element (SE) compliant to the standard will be able to produce a “qualified electronic signature” that fulfils the requirements of section 4, in particular Articles 26 (requirements for advanced electronic signatures) and 29 (requirements for qualified electronic signature creation devi

22、ces) of the so-called eIDAS Regulation and therefore can be considered equivalent to a hand-written signature.This standard consists of five parts: Part 1: “Introduction and common definitions” describes the history, application context, market perspective and a tutorial about the basic understandin

23、g of electronic signatures. It also provides common terms and references valid for the entire 419212 series. Part 2: “Signature and Seal Services” describes the specifications for signature generation according to the eIDAS regulation. Part 3: “Device Authentication” describes the device authenticat

24、ion protocols and the related key management services to establish a secure channel. Part 4: “Privacy specific Protocols” describes functions and services to provide privacy to identification services.

34、sms for security operations3 Introduction3.1 GeneralPrivacy Context is an environment to be considered whereas a card holder may be exposed to an environment that might read privacy parameters from the card ahead of any device authentication. Such privacy parameters can be the unique Card ID or othe

35、r personalized parameters that allow a tracking and profiling of the card holder.For instance, if the nationality of a card holder can be identified by the nature of the card description parameters (e.g. algorithm ID), then a card holder of certain nationality could be exposed to observation. Privac

36、y context describes the requirement to allow a card holder to be confident that privacy parameters will not be exposed to unauthorized environment.ICC Cards used for eID functionality may need as well privacy features e.g. to conceal the identity or the specific profile of the ICC owner in open netw

37、orks or for Machine to Machine (M2M) services.One popular functionality represents the well known use of pseudonyms here implemented by the restricted identification or 4.3 “Enhanced Role Authentication (ERA) protocol” with the purpose that these pseudonyms are used for certain services (e.g. paymen

38、t sector) and cannot be linked to a global profile of the owner.Another application lies in the validation of the ICC for authorization to web services, (e.g. voting) where only as much information is to be revealed as necessary for the actual service. Another popular use is the age verification wit

39、h information provided only to the extent that a person is older than a particular age but without revealing the actual age of the card holder.Different privacy oriented protocols are described in the following sections.5BS EN 419212-4:2018EN 419212-4:2018 (E)3.2 Auxiliary Data Comparison3.2.1 Gener

40、alThe COMPARE command specified in ISO/IEC 7816-4:2013, initiates a comparison of “comparison data” with non-volatile “reference data” in the ICC. The comparison data are provided by the IFD either in the COMPARE command or by an operation prior to the comparison e.g. as Auxiliary Data as described

41、in EN 419212-3:2017, 3.6.4.5.As with coding the comparison data in the compare command the command could be sent multiple times, the IFD could evaluate the actual auxiliary data (e.g. age) by additional verification attempts on selected auxiliary data content (e.g. variable age).If the IFD is allowe

42、d to send the compare command only once, then such an attempt may be avoided. Sending the comparison data as auxiliary data within device authentication protocols as specified in this standard, avoid those attacks. The presentation of the auxiliary data are shown in 3.2.3 and shall be implemented ac

43、cording to TR 03110 2.20.The presentation of auxiliary data are mandatorily to be provided by the General Authentication Procedure (GAP) according to TR 03110 2.20.As there are several further options to prevent from exhaustive search and the actual exposure cannot be generalized due to the fact tha

44、t the actual content of auxiliary data are not specified in this standard, the associated countermeasures to the above situation are out of the scope of this standard.For the additional services several use cases e.g. perform age verification, document validity verification or other comparison are p

45、ossible.Each of these use cases requires an appropriate usage of the COMPARE command regarding P1, P2, and the data field. These parameters are described in the following.The successful execution of the COMPARE command has no result on the internal status of the card.3.2.2 Presentation of the auxili

46、ary dataThe auxiliary data are presented as part of the mEAC protocol (EN 419212-3:2017, clause 3.6), in two possible variants. These variants are described above and shown in Table 1.Auxiliary data may have use cases as in the following examples:- For Age Verification the terminal has to send the r

47、equired date of birth threshold.- For Document Validity Verification the terminal has to send the current dateThe following is an example that shows Table 34 in Part 3 but highlights the added steps relevant to the verification of the auxiliary data.
