Introduction
ETSI TR 119 000 [i.1] provides a general structure for electronic signatures standardization outlining existing and
potential standards for digital signatures. This identifies six areas of standardization with a list of existing and potential
future standards in each area.
This guide is one of a series of guidance documents on selection of standards and options for digital signatures to assist
users and their suppliers in identifying the standards and options relevant to their need. Each guide addresses a
particular area as identified in the ETSI TR 119 000 [i.1].
This series is based on the process of selecting Business Scoping Parameters for each area of standardization based on
an analysis of the business requirements. The selection of these scoping parameters is based on a process involving an
analysis of the business requirements and associated risks leading to an identification of the policy and security
requirements and the resulting Business Scoping Parameters from which the appropriate standards and options can be
selected. Having identified the requirements in terms of Business Scoping Parameters for an area, each guidance
document provides assistance in selecting the appropriate standards and options for that area.
This guidance does not include any normative requirements but provides guidance on addressing the Trust Application
Service Providers (TASP) area, on the selection of applicable standards and their options for a particular business
implementation context and associated business requirements.

TASP covers Trust Service Providers offering value added services applying digital signatures and that rely on the
generation/validation of digital signatures in normal operation. This includes namely registered mail and other
e-delivery services, as well as data preservation (long term archiving) services. This list may be extended as further
services applying electronic signatures are identified.
This general process of the selection of standards and options is described further in ETSI TR 119 000 [i.1],
clause 4.2.6.

1 Scope
The present document provides guidance on the use of standards for Trust Application Service Providers (area 5) as
identified in the framework for standardization of signatures: overview [i.1].
The present document then describes the Business Scoping Parameters relevant to this area (see clause 6) and how the
relevant standards and options for this area can be identified given the Business Scoping Parameters (clause 7).
The target audience of the present document includes:
1) Business managers who potentially require support from digital signatures in their business will find here an
understandable explanation of how services applying digital signatures standards can be used to meet their
business needs.
2) Application architects who will find here material that will guide them throughout the difficult process of
designing a system that fully and properly satisfies all the business and legal/regulatory requirements specific
to services applying digital signatures, and will gain a better understanding on how to select the appropriate
standards to be implemented and/or used.
3) Developers of the systems who will find an understanding of a good part of the ultimate reasons that led the
systems to be designed as they were, as well as a proper knowledge of the standards that exist in the field and
to be known in detail for a proper development.
