Lack of trust, in particular because of a perceived lack of security, makes consumers, businesses and administrations hesitate to carry out transactions electronically and to adopt new services. Trust service providers are often an essential element to establish trust between parties transacting electronically, particularly in open public networks, and can be used, for example, to provide trusted identity information and help establish secure communications between transacting parties. Examples of such trust service providers are issuers of public key certificates, time-stamping service providers, providers of remote electronic signature generation or validation services. SIST EN 319 401 V2.2.1:2018

ETSI ETSI EN 319 401 V2.2.1 (2018-04) 5 For participants of electronic commerce to have confidence in the security of these trust services they need to have confidence that the trust service providers (TSPs) have established a set of procedures, processes and security measures in order to minimize the operational and financial threats and risks associated. The present document specifies baseline policy requirements on the operation and management practices of TSP regardless the service they provide. Other standards, addressing particular type of trust service, can build on the present document to identify supplement requirements for particular type of trust service. The present document is aiming to meet the general requirements to provide trust and confidence in electronic transactions including, amongst others, applicable requirements from Regulation (EU) No 910/2014 [i.2] and those from CA/Browser Forum [i.4]. EXAMPLE: ETSI EN 319 411-2 [i.11] annex A describes the application of the present document to the requirements of Regulation No 910/2014 [i.2] requirements for TSPs issuing EU qualified certificates.

Introduction

Building trust in the online environment is key to economic and social development. Lack of trust, in particular because

of a perceived lack of security, makes consumers, businesses and administrations hesitate to carry out transactions

electronically and to adopt new services. Trust service providers are often an essential element to establish trust

between parties transacting electronically, particularly in open public networks, and can be used, for example, to

provide trusted identity information and help establish secure communications between transacting parties. Examples of

such trust service providers are issuers of public key certificates, time-stamping service providers, providers of remote

electronic signature generation or validation services.
ETSI
---------------------- Page: 4 ----------------------
5 ETSI EN 319 401 V2.2.1 (2018-04)

For participants of electronic commerce to have confidence in the security of these trust services they need to have

confidence that the trust service providers (TSPs) have established a set of procedures, processes and security measures

in order to minimize the operational and financial threats and risks associated.

The present document specifies baseline policy requirements on the operation and management practices of TSP

regardless the service they provide. Other standards, addressing particular type of trust service, can build on the present

document to identify supplement requirements for particular type of trust service.

The present document is aiming to meet the general requirements to provide trust and confidence in electronic

transactions including, amongst others, applicable requirements from Regulation (EU) No 910/2014 [i.2] and those

from CA/Browser Forum [i.4].

EXAMPLE: ETSI EN 319 411-2 [i.11] annex A describes the application of the present document to the

requirements of Regulation No 910/2014 [i.2] requirements for TSPs issuing EU qualified

certificates.
ETSI
---------------------- Page: 5 ----------------------
6 ETSI EN 319 401 V2.2.1 (2018-04)
1 Scope

The present document specifies general policy requirements relating to trust service providers (TSPs) that are

independent of the type of TSP. It defines policy requirements on the operation and management practices of TSPs.

Other specifications refine and extend these requirements as applicable to particular forms of TSP. The present

document does not specify how the requirements identified can be assessed by an independent party, including

requirements for information to be made available to such independent assessors, or requirements on such assessors.

NOTE: See ETSI EN 319 403 [i.6]: "Electronic Signatures and Infrastructures (ESI); Requirements for

conformity assessment bodies assessing Trust Service Providers".

between parties transacting electronically, particularly in open public networks, and can be used, for example, to

provide trusted identity information and help establish secure communications between transacting parties. Examples of

such trust service providers are issuers of public key certificates, time-stamping service providers, providers of remote

electronic signature generation or validation services.

5 Final draft ETSI EN 319 401 V2.2.1 (2018-02)

For participants of electronic commerce to have confidence in the security of these trust services they need to have

confidence that the trust service providers (TSPs) have established a set of procedures, processes and security measures

in order to minimize the operational and financial threats and risks associated.

The present document specifies baseline policy requirements on the operation and management practices of TSP

regardless the service they provide. Other standards, addressing particular type of trust service, can build on the present

document to identify supplement requirements for particular type of trust service.

The present document is aiming to meet the general requirements to provide trust and confidence in electronic

transactions including, amongst others, applicable requirements from Regulation (EU) No 910/2014 [i.2] and those

from CA/Browser Forum [i.4].

EXAMPLE: ETSI EN 319 411-2 [i.11] annex A describes the application of the present document to the

requirements of Regulation No 910/2014 [i.2] requirements for TSPs issuing EU qualified

certificates.

1 Scope

The present document specifies general policy requirements relating to trust service providers (TSPs) that are

independent of the type of TSP. It defines policy requirements on the operation and management practices of TSPs.

Other specifications refine and extend these requirements as applicable to particular forms of TSP. The present

document does not specify how the requirements identified can be assessed by an independent party, including

requirements for information to be made available to such independent assessors, or requirements on such assessors.

NOTE: See ETSI EN 319 403 [i.6]: "Electronic Signatures and Infrastructures (ESI); Requirements for

Introduction

Building trust in the online environment is key to economic and social development. Lack of trust, in particular because

of a perceived lack of security, makes consumers, businesses and administrations hesitate to carry out transactions

electronically and to adopt new services. Trust service providers are often an essential element to establish trust

between parties transacting electronically, particularly in open public networks, and can be used, for example, to

provide trusted identity information and help establish secure communications between transacting parties. Examples of

such trust service providers are issuers of public key certificates, time-stamping service providers, providers of remote

electronic signature generation or validation services.
ETSI
---------------------- Page: 4 ----------------------
5 Draft ETSI EN 319 401 V2.2.0 (2017-08)

For participants of electronic commerce to have confidence in the security of these trust services they need to have

confidence that the trust service providers (TSPs) have established a set of procedures, processes and security measures

in order to minimize the operational and financial threats and risks associated.

The present document specifies baseline policy requirements on the operation and management practices of TSP

regardless the service they provide. Other standards, addressing particular type of trust service, can build on the present

document to identify supplement requirements for particular type of trust service.

The present document is aiming to meet the general requirements to provide trust and confidence in electronic

transactions including, amongst others, applicable requirements from Regulation (EU) No 910/2014 [i.2] and those

from CA/Browser Forum [i.4].

EXAMPLE: ETSI EN 319 411-2 [i.11] annex A describes the application of the present document to the

requirements of Regulation No 910/2014 [i.2] requirements for TSPs issuing EU qualified

certificates.

1 Scope

The present document specifies general policy requirements relating to trust service providers (TSPs) that are

independent of the type of TSP. It defines policy requirements on the operation and management practices of TSPs.

Other specifications refine and extend these requirements as applicable to particular forms of TSP. The present

document does not specify how the requirements identified can be assessed by an independent party, including

requirements for information to be made available to such independent assessors, or requirements on such assessors.

NOTE: See ETSI EN 319 403 [i.6]: "Electronic Signatures and Infrastructures (ESI); Requirements for

conformity assessment bodies assessing Trust Service Providers".
