ETSI ETSI EN 319 532-2 V1.1.1 (2018-09) 5 Introduction Business and administrative relationships among companies, public administrations and private citizens are the more and more implemented electronically. Trust is essential for their success and continued development of electronic services. It is therefore important that any entity using electronic services have suitable security controls and mechanisms in place to protect their transactions and to ensure trust and confidence with their partners. Electronic signatures are commonly used worldwide to ensure authenticity and integrity of electronic documents, making it possible to transform traditional paper-based processes into electronic ones providing a comparable or even higher level of assurance. As communication is becoming predominantly internet-based, secure and provable exchange of documents is essential to the full digital transformation. An electronic registered delivery service (ERDS hereinafter) provides secure and reliable delivery of electronic messages between parties, producing evidence of the delivery process for legal accountability. Evidence can be seen as a declaration by a trusted party that a specific event related to the delivery process (submission of a message, relay of a message, delivery of a message, refusal of a message, etc.) happened at a certain time. Evidence can be immediately delivered to the interested party (together with the message or separately) or can be kept in a repository for later access. It is common practice to implement evidence as digitally signed data. Registered electronic mail (REM hereinafter) is a specific type of electronic registered delivery, which builds on the formats, protocols and mechanisms used in ordinary e-mail messaging. In a number of national, regional or sector-specific communities electronic registered delivery and registered electronic mail services are already in place, and even more are being developed. Without the definition of common standards there will be no consistency in the services provided, making it difficult for users to compare them. Under these circumstances, users might be prevented from easily changing to alternative providers, damaging free competition. Lack of standardization might also adversely affect interoperability between implementations which are based on different models. The present document is one of a set of interrelated documents (framework of ERDS standards hereinafter) ETSI has produced to facilitate a consistent form of electronic registered delivery service inside and outside Europe, especially with regard to the form of evidence provided, in order to maximize interoperability even between domains governed by different policy rules. This set of documents includes the following deliverables: • ETSI EN 319 522 [i.10]: a multi-part deliverable providing technical specifications for Electronic Registered Delivery Services. • ETSI EN 319 532 [i.11]: a multi-part deliverable providing technical specifications for Registered Electronic Mail Services. • ETSI EN 319 521 [i.12]: providing Policy and Security Requirements for Electronic Registered Delivery Service Providers. • ETSI EN 319 531 [i.13]: providing Policy and Security Requirements for Registered Electronic Mail Service Providers. • ETSI TS 119 524 [i.14]: a multi-part deliverable providing requirements for Testing Conformance and Interoperability of Electronic Registered Delivery Services. • ETSI TS 119 534 [i.15]: a multi-part deliverable providing requirements for Testing Conformance and Interoperability of Registered Electronic Mail Services. The documents covering ERDS contain the general concepts and requirements which apply to all kinds of electronic registered delivery services. Since REM is a specific type of electronic registered delivery, the documents covering REM service build on the corresponding documents covering ERDS by referencing the necessary provisions, and define the interpretation and specific requirements which apply only to registered electronic mail. SIST EN 319 532-2 V1.1.1:2018

ETSI ETSI EN 319 532-2 V1.1.1 (2018-09) 6 Regulation (EU) No 910/2014 of the European Parliament and of the Council of 23 July 2014 on electronic identification and trust services for electronic transactions in the internal market and repealing Directive 1999/93/EC [i.2] (Regulation (EU) No 910/2014, or Regulation hereinafter) provides a legal framework to facilitate cross-border recognition between existing national legal systems related to electronic registered delivery services. That framework aims to open new market opportunities for European Union trust service providers to offer new pan-European electronic registered delivery services. The Regulation defines the so-called qualified electronic registered delivery service (QERDS hereinafter), which is a special type of ERDS, where both the service and its provider need to meet a number of additional requirements that the regular ERDSs and their providers do not need to meet. The framework of ERDS standards aims to cover the common and worldwide-recognized requirements to address electronic registered delivery in a secure and reliable way, independent of the applicable legislative framework. The documents contain generic requirements which can be applied in any geographic region. At the same time, the framework of ERDS standards aims to support demonstrating compliance to the Regulation (EU) No 910/2014 (and related secondary legislation), both for non-qualified and qualified electronic registered delivery services. Specific clauses are included defining requirements for qualified services only, especially in the documents covering policy and security requirements. However, the legal effects of services implemented according to the framework of ERDS standards are outside the scope of the documents [i.10] to [i.15]. The present document is part 2 of ETSI EN 319 532 [i.11], which is a multi-part deliverable covering Registered Electronic Mail (REM) Services, as detailed in the Foreword. ETSI EN 319 522 [i.10] contains the general concepts and requirements which apply to all kinds of ERDSs. Since registered electronic mail is a specific type of electronic registered delivery, the general provisions given in ETSI EN 319 522 [i.10] apply to registered electronic mail as well. Hence, parts 1 and 2 of ETSI EN 319 532 [i.11] are aligned with ETSI EN 319 522 [i.11], and they reference the necessary provisions of the corresponding part.

Introduction

Business and administrative relationships among companies, public administrations and private citizens are the more

and more implemented electronically. Trust is essential for their success and continued development of electronic

services. It is therefore important that any entity using electronic services have suitable security controls and

mechanisms in place to protect their transactions and to ensure trust and confidence with their partners.

Electronic signatures are commonly used worldwide to ensure authenticity and integrity of electronic documents,

making it possible to transform traditional paper-based processes into electronic ones providing a comparable or even

higher level of assurance. As communication is becoming predominantly internet-based, secure and provable exchange

of documents is essential to the full digital transformation.

An electronic registered delivery service (ERDS hereinafter) provides secure and reliable delivery of electronic

messages between parties, producing evidence of the delivery process for legal accountability. Evidence can be seen as

a declaration by a trusted party that a specific event related to the delivery process (submission of a message, relay of a

delivered to the interested party (together with the message or separately) or can be kept in a repository for later access.

It is common practice to implement evidence as digitally signed data. Registered electronic mail (REM hereinafter) is a

specific type of electronic registered delivery, which builds on the formats, protocols and mechanisms used in ordinary

there will be no consistency in the services provided, making it difficult for users to compare them. Under these

circumstances, users might be prevented from easily changing to alternative providers, damaging free competition. Lack

of standardization might also adversely affect interoperability between implementations which are based on different

The present document is one of a set of interrelated documents (framework of ERDS standards hereinafter) ETSI has

produced to facilitate a consistent form of electronic registered delivery service inside and outside Europe, especially

with regard to the form of evidence provided, in order to maximize interoperability even between domains governed by

different policy rules. This set of documents includes the following deliverables:

6 ETSI EN 319 532-2 V1.1.1 (2018-09)

Regulation (EU) No 910/2014 of the European Parliament and of the Council of 23 July 2014 on electronic

identification and trust services for electronic transactions in the internal market and repealing Directive

1999/93/EC [i.2] (Regulation (EU) No 910/2014, or Regulation hereinafter) provides a legal framework to facilitate

cross-border recognition between existing national legal systems related to electronic registered delivery services. That

framework aims to open new market opportunities for European Union trust service providers to offer new

pan-European electronic registered delivery services. The Regulation defines the so-called qualified electronic

registered delivery service (QERDS hereinafter), which is a special type of ERDS, where both the service and its

provider need to meet a number of additional requirements that the regular ERDSs and their providers do not need to

meet.

The framework of ERDS standards aims to cover the common and worldwide-recognized requirements to address

electronic registered delivery in a secure and reliable way, independent of the applicable legislative framework. The

documents contain generic requirements which can be applied in any geographic region. At the same time, the

framework of ERDS standards aims to support demonstrating compliance to the Regulation (EU) No 910/2014 (and

related secondary legislation), both for non-qualified and qualified electronic registered delivery services. Specific

clauses are included defining requirements for qualified services only, especially in the documents covering policy and

security requirements. However, the legal effects of services implemented according to the framework of ERDS

standards are outside the scope of the documents [i.10] to [i.15].

The present document is part 2 of ETSI EN 319 532 [i.11], which is a multi-part deliverable covering Registered

Electronic Mail (REM) Services, as detailed in the Foreword. ETSI EN 319 522 [i.10] contains the general concepts and

requirements which apply to all kinds of ERDSs. Since registered electronic mail is a specific type of electronic

registered delivery, the general provisions given in ETSI EN 319 522 [i.10] apply to registered electronic mail as well.

Hence, parts 1 and 2 of ETSI EN 319 532 [i.11] are aligned with ETSI EN 319 522 [i.11], and they reference the

necessary provisions of the corresponding part.

Introduction

Business and administrative relationships among companies, public administrations and private citizens are the more

and more implemented electronically. Trust is essential for their success and continued development of electronic

services. It is therefore important that any entity using electronic services have suitable security controls and

mechanisms in place to protect their transactions and to ensure trust and confidence with their partners.

ETSI
---------------------- Page: 4 ----------------------
5 Draft ETSI EN 319 532-2 V1.0.0 (2018-05)

Electronic signatures are commonly used worldwide to ensure authenticity and integrity of electronic documents,

making it possible to transform traditional paper-based processes into electronic ones providing a comparable or even

higher level of assurance. As communication is becoming predominantly internet-based, secure and provable exchange

of documents is essential to the full digital transformation.

An electronic registered delivery service (ERDS hereinafter) provides secure and reliable delivery of electronic

messages between parties, producing evidence of the delivery process for legal accountability. Evidence can be seen as

a declaration by a trusted party that a specific event related to the delivery process (submission of a message, relay of a

message, delivery of a message, refusal of a message, etc.) happened at a certain time. Evidence can be immediately

delivered to the interested party (together with the message or separately) or can be kept in a repository for later access.

It is common practice to implement evidence as digitally signed data. Registered electronic mail (REM hereinafter) is a

specific type of electronic registered delivery, which builds on the formats, protocols and mechanisms used in ordinary

e-mail messaging.

In a number of national, regional or sector-specific communities electronic registered delivery and registered electronic

mail services are already in place, and even more are being developed. Without the definition of common standards

there will be no consistency in the services provided, making it difficult for users to compare them. Under these

circumstances, users might be prevented from easily changing to alternative providers, damaging free competition. Lack

of standardization might also adversely affect interoperability between implementations which are based on different

models.

The present document is one of a set of interrelated documents (framework of ERDS standards hereinafter) ETSI has

produced to facilitate a consistent form of electronic registered delivery service inside and outside Europe, especially

with regard to the form of evidence provided, in order to maximize interoperability even between domains governed by

different policy rules. This set of documents includes the following deliverables:

� ETSI EN 319 522 [i.10]: a multi-part deliverable providing technical specifications for Electronic Registered

Delivery Services.

� ETSI EN 319 532 [i.11]: a multi-part deliverable providing technical specifications for Registered Electronic

Mail Services.

� ETSI EN 319 521 [i.12]: providing Policy and Security Requirements for Electronic Registered Delivery

Service Providers.

� ETSI EN 319 531 [i.13]: providing Policy and Security Requirements for Registered Electronic Mail Service

Providers.

� ETSI TS 119 524 [i.14]: a multi-part deliverable providing requirements for Testing Conformance and

Interoperability of Electronic Registered Delivery Services.

� ETSI TS 119 534 [i.15]: a multi-part deliverable providing requirements for Testing Conformance and

Interoperability of Registered Electronic Mail Services.

The documents covering ERDS contain the general concepts and requirements which apply to all kinds of electronic

registered delivery services. Since REM is a specific type of electronic registered delivery, the documents covering

REM service build on the corresponding documents covering ERDS by referencing the necessary provisions, and define

the interpretation and specific requirements which apply only to registered electronic mail.

Regulation (EU) No 910/2014 of the European Parliament and of the Council of 23 July 2014 on electronic

identification and trust services for electronic transactions in the internal market and repealing Directive 1999/93/EC

[i.2] (Regulation (EU) No 910/2014, or Regulation hereinafter) provides a legal framework to facilitate cross-border

recognition between existing national legal systems related to electronic registered delivery services. That framework

aims to open new market opportunities for European Union trust service providers to offer new pan-European electronic

registered delivery services. The Regulation defines the so-called qualified electronic registered delivery service

(QERDS hereinafter), which is a special type of ERDS, where both the service and its provider need to meet a number

of additional requirements that the regular ERDSs and their providers do not need to meet.

ETSI
---------------------- Page: 5 ----------------------
6 Draft ETSI EN 319 532-2 V1.0.0 (2018-05)

The framework of ERDS standards aims to cover the common and worldwide-recognized requirements to address

electronic registered delivery in a secure and reliable way, independent of the applicable legislative framework. The

documents contain generic requirements which can be applied in any geographic region. At the same time, the

framework of ERDS standards aims to support demonstrating compliance to the Regulation (EU) No 910/2014 (and

related secondary legislation), both for non-qualified and qualified electronic registered delivery services. Specific

clauses are included defining requirements for qualified services only, especially in the documents covering policy and

security requirements. However, the legal effects of services implemented according to the framework of ERDS

standards are outside the scope of the documents [i.10] to [i.15].

The present document is part 2 of ETSI EN 319 532 [i.11], which is a multi-part deliverable covering Registered

Electronic Mail (REM) Services, as detailed in the Foreword. ETSI EN 319 522 [i.10] contains the general concepts and

requirements which apply to all kinds of ERDSs. Since registered electronic mail is a specific type of electronic

registered delivery, the general provisions given in ETSI EN 319 522 [i.10] apply to registered electronic mail as well.

Hence, parts 1 and 2 of ETSI EN 319 532 [i.11] are aligned with ETSI EN 319 522 [i.11], and they reference the

necessary provisions of the corresponding part.
