21、orial environment”, the secretariat of which is held by AFNOR.This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2018, and conflicting national standards shall be withdrawn at the latest by O
22、ctober 2018.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights.This document supersedes EN 419212-1:2014 and EN 419212-2:2014.This standard supports serv
23、ices 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, defining the functional and security features for a Secure E
24、lements (SE) (e.g. smart cards) intended to be used as a Qualified electronic Signature Creation Device (QSCD) according to the Terms of the “European Regulation on Electronic Identification and Trust Services for electronic transactions in the internal market” 22.A Secure Element (SE) compliant to
25、the standard will be able to produce a “qualified electronic signature” that fulfils the requirements of Article of the Electronic Signature Regulation ” 22 and therefore can be considered equivalent to a hand-written signature.This standard consists of five parts:Part 1: “Introduction and common de
26、finitions” describes the history, application context, market perspective and a tutorial about the basic understanding 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 sig
27、nature generation according to the eIDAS regulation. Part 3: “Device Authentication” describes the device authentication 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 identi
28、fication services. Part 5: “Trusted eServices” describes services that may be used in conjunction with signature services described in Part 2.

35、2 to enable interoperability and usage for IAS services on a national or European level.It also specifies additional mechanisms like key decipherment, Client Server authentication, identity management and privacy related services.2 Normative referencesThe following documents, in whole or in part, ar

39、iations apply as described in EN 419212-1.5 Additional Service SelectionAdditional services are typically used in the context of applications that use digital signatures.A well-known additional service is the client/server authentication. In this case, the ICC is used as a crypto toolbox, e.g. in or
40、der to encrypt a challenge with a private key, being stored in the ICC. This is particularly helpful in applications, where a tamper resistant device is required for client/server authentication. A secure ICC has the necessary tamper resistant quality and may therefore be used efficiently to support
41、 the application in this context.Document decryption is another known service which may be performed by the IFD. A terminal application receives a document, typically encrypted with a symmetric key. The symmetric key is also provided encrypted with a public key. The ICC contains the appropriate priv
42、ate key, deciphers the symmetric key and returns it to the terminal application.While the typical usage of a signature card is the generation of a digital signature, an application might want to verify a signature with a public key, being stored in the ICC. In this case an additional service is invo
43、ked for signature verification.ICCs used as national identification cards, travel documents or driving licences generally provide additional applications to enable eServices (e.g. eGovernment, eBusiness, ) including an ESIGN application. In the eID card context new privacy issues are to be put into
44、account, e.g. user tracking, 1) Available at http:/ BS EN 419212-5:2018EN 419212-5:2018 (E)data minimizing, unlinkability of transactions or domain specific identifiers. This standard specifies privacy preserving protocols and mechanisms as additional services.Additional services provided in the IC
45、C mandate the existence of an appropriate security environment. Associated security environments are described in EN 419212-2:2017, Annex A.In addition to the descriptive information found in DF.CIA (refer to EN 419212-2, clause 14) information might be required that can be presented in Security Ser
46、vice Descriptors. The concept of Security Service Descriptors is described in the Annex A.A user verification may be required prior to the usage of additional services. The password for this user verification shall be different from the password used for the signature generation. This is to maintain
47、 the purpose of the signature generation password for the sole purpose of a declaration of will in the case of a signature generation.Figure 1 shows an execution flow for an additional service. The corresponding technical implementation is given in this document.7BS EN 419212-5:2018EN 419212-5:2018
