Electronic Signatures and Infrastructures (ESI); ASiC Baseline Profile
|Publication Date:||1 June 2013|
The present document defines a baseline profile for ASiC that provides the basic features necessary for a wide range of business and governmental use cases for electronic procedures and communications to be applicable to a wide range of communities when there is a clear need for interoperability of AdES signatures, on which ASiC is based, to be interchanged across borders. In particular it takes into account needs for interoperability of AdES signatures used in electronic documents issued by competent authorities to be interchanged across borders in the context of the EU Services Directive [i.3].
The profile defines three different conformance levels addressing incremental requirements to maintain the validity of the container signatures over the long term based on the corresponding conformance levels specified in CAdES  and XAdES  profiles, in a way that all the requirements addressed at a certain level are always addressed also by the levels above. Each level requires the presence of certain attributes in the container signature, suitably profiled for reducing the optionality as much as possible and referring to the forms that are specified in CAdES  or XAdES  as applicable.
NOTE: The mentioned CAdES and XAdES profiles define an additional LTA (Long Term Archive time-stamps) conformance level that allow validation of the signature long time after its generation. An equivalent level for AsiC requires a revision of the mother specification (currently TS 102 918  (V1.2.1)). It is anticipated that the present document will be updated to include the LTA level when a suitable version of the AsiC mother specification will be available.
Clause 2 in the present document contains references to the relevant documents and standards.
Clause 3 includes definitions of relevant terms and abbreviations used in the present document.
Clause 4 identifies the three conformance levels and shows how these levels might encompass the life cycle of the electronic signatures.
Clause 5 provides details on the way that the requirements on both signer and verifier will be presented throughout the present document.
Clauses 6, 7 and 8 specify the requirements for ASiC containers that are applicable to all the conformance levels specified in clause 4. Clause 6 specifies profiling requirements for elements common to all ASiC containers while clauses 7 and 8 specify profile requirements related to ASiC-S and ASiC-E respectively.
