Intellectual Property Rights
Essential patents
IPRs essential or potentially essential to normative deliverables may have been declared to ETSI. The information
pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in
respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web
server (https://ipr.etsi.org/).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee
can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web
server) which are, or may be, or may become, essential to the present document.
Trademarks
The present document may include trademarks and/or tradenames which are asserted and/or registered by their owners.
ETSI claims no ownership of these except for any which are indicated as being the property of ETSI, and conveys no
right to use or reproduce any trademark and/or tradename. Mention of those trademarks in the present document does
not constitute an endorsement by ETSI of products, services or organizations associated with those trademarks.
Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Electronic Signatures and
Infrastructures (ESI).
The present document is part 3 of a multi-part deliverable. Full details of the entire series can be found in part 1 [i.2].
Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.

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.
