EN 419212-3:2017 (E) 5 European foreword This document (EN 41921-3:2017) has been prepared by CEN/TC 224 “Personal identification, electronic signature and cards and their related systems and operations”, 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of an identical text or by endorsement, at the latest by March 2018, and conflicting national standards shall be withdrawn at the latest by March 2018. This document supersedes EN 419212-1:2014 and EN 419212-2:2014. This document has been prepared under a mandate given to CENELEC by the European Commission and the European Free Trade Association. 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, defining the functional and security features for a Secure Elements (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” [1]. A Secure Element (SE) compliant to the standard will be able to produce a “qualified electronic signature” that fulfils the requirements of Article of the Electronic Signature Regulation [1] 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 understanding of electronic signatures. It also provides common terms and references valid for the entire 419212 series. [24] Part 2: “Signature and Seal Services” describes the specifications for signature generation according to the eIDAS regulation. [25] Part 3: “Device Authentication” describes the device authentication protocols and the related key management services to establish a secure channel. [26] Part 4: “Privacy specific Protocols” describes functions and services to provide privacy to identification services. [27] Part 5: “Trusted eServices” describes services that may be used in conjunction with signature services described in Part 2. [28] According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

Device authentication protocols;
Establishment of a secure channel;
Data structures;
CV-certificates;
Key management. The device authentication protocols should apply to sole-control signature mandated by the EU-regulation eIDAS [1]. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

Device authentication requires mandatory steps in order to provide a secure authentication. A device authentication is mutual and combines two mechanisms: - an ICC verifies the external world (TDA) and itself verified by the external world (CDA); - the two devices negotiate or exchange information to establish common symmetric session keys for subsequent operations. SIST EN 419212-3:2018



EN 419212-3:2017 (E) 8 After negotiation of the symmetric keys, a secure session is established. A secure session is a cryptographic protection of the messages from both sides. The cryptographic protection can be: - a cryptographic checksum on a plain text for integrity protection and/or - an encrypted message text for confidentiality protection (mandates cryptographic checksum). Refer to “9 Secure Messaging” [25]. For performance reasons, the secure messaging keys are symmetric keys. Therefore this document describes the establishment of symmetric session keys only, and does not consider an option for asymmetric session keys. Once the session keys are established, a trusted channel is available to protect or conceal the information transmitted over the interface. The application of Secure Messaging (SM) is mandatory for every subsequent operation to ensure the provision of an entirely trusted channel. For exceptions refer to “5.3 Selection of ESIGN application” [25]. The conditions to end a secure messaging session are given in 3.12. This chapter describes the following device authentication mechanisms - asymmetric session key transport mechanism based on RSA; - asymmetric session key agreement mechanism with privacy protection; - asymmetric session key agreement mechanism with non-traceability and privacy protection; - symmetric authentication mechanism in order to perform a mutual authentication protocol between IFD and ICC. The presentation of the asymmetric schemes is sequentially staged in order to trade off the security features with the required complexity of the authentication protocols. NOTE
Authentication in general requires a defined order of steps to be processed. Violation of this order may result in the ICC aborting the process. The mechanism to control the proper order of execution steps are out of the scope of this standard. In order to distinguish which device authentication is the most appropriate for a given situation refer to Annex A. For the use of certificates the following table indicates the correct certificate type for each device authentication protocol.

They contain some mandatory aspects of the device authentication protocols considered to comply with the claims of the ESIGN-G1 [23] document. - The public key of the IFD shall not be used until successfully verified by a certificate. - The device to
