1 Scope
The present document defines an ASN.1 format of machine readable signature policies based on the building blocks
that define technical constraints on digital signatures and are specified in ETSI TS 119 172-1 [i.2].
Pure signature applicability rules, directly related to procedural constraints imposed by business processes, are out of
the scope of the present document which does not define ASN.1 elements for the building blocks specified in ETSI
TS 119 172-1 [i.2] defining only applicability rules.
For each element of the machine readable signature policy, the present document references to the semantics described
in ETSI TS 119 172-2 [3] and defines the corresponding ASN.1 syntax.
The present document defines elements which can be used to describe technical constraints on signature creation,
signature validation, and signature augmentation. These elements are designed in a way that it is possible to generate
ASN.1 documents that include components of a signature generation policy, or/and signature validation policy, and/or
signature augmentation policy.
An ASN.1 document conformant to the present specification, defines constraints (on generation, augmentation,
validation, any combination of two of them, or the three of them) that one signature has to meet.
NOTE: Complex business processes, where several digital signatures need to be managed, having to meet
different set of technical constraints, will require several ASN.1 documents conformant to the present
document, each one defining one of these sets of technical constraints.
It is out of the scope to specify mechanisms for protecting the integrity of the machine-readable signature policy
documents specified in the present document.

3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the terms given in ETSI TS 119 172-1 [i.2] and the following apply:
signature applicability rules: set of rules, applicable to one or more digital signatures, that defines the requirements
for determination of whether a signature is fit for a particular business or legal purpose
signature augmentation constraint: criteria used when augmenting a digital signature
signature augmentation policy: set of signature augmentation constraints
signature creation application: application within the signature creation system that creates the AdES digital signature
and relies on the signature creation device to create a digital signature value
signature creation constraint: criteria used when creating a digital signature
signature creation policy: set of signature creation constraints processed or to be processed by the signature creation
application
signature validation application: application that validates a signature against a signature validation policy, and that
outputs a status indication (i.e. the signature validation status) and a signature validation report
signature validation constraint: technical criteria against which a digital signature can be validated
EXAMPLE: As specified in ETSI TS 119 102-1 [i.1].
signature validation policy: set of signature validation constraints processed or to be processed by the signature
validation application

4.1 Introduction
4.1.1 Technical approach
The present document takes as starting point the contents of ETSI TS 119 172-1 [i.2], which defines the building blocks
of a human readable signature policy document. These building blocks are of two types:
• Building blocks defining applicability rules, which are the procedural constraints enforced by the business
processes where the digital signatures are used. These procedural constraints, if not satisfied, could prevent
further processing (in other words, accepting for the purpose of the business) a certain signed document even if
the digital signature is technically valid.
• Building blocks defining technical constraints, related with technical aspects of the digital signature and its
technical validation (signature format, signature attributes, constraints on certificates, time-stamp tokens,
revocation material data, etc.).
