ETSI TS 119 162-1

The present document specifies Associated Signature Containers (ASiC) which bind together into one single digitalcontainer based on ZIP [5] either detached digital signatures or time-assertions, with a number of file objects (e.g. documents, XML structured data, spreadsheet, multimedia content) to which they apply.

The present document specifies general purpose ASiC containers building blocks and a limited set of baseline containers.

ASiC supports the following signature and time assertion formats:

• CAdES digital signatures (ETSI TS 119 122-1 [1] and ETSI TS 119 122-2 [11]);
• XAdES digital signatures (ETSI TS 119 132-1 [2] and ETSI TS 119 132-2 [12]);
• IETF RFC 3161 [3] and updated by IETF RFC 5816 [13] time-stamp tokens; and
• IETF RFC 4998 [8] or IETF RFC 6283 [9] evidence records.

NOTE: No restriction is placed on time assertions eventually used within CAdES/XAdES.

The building blocks defined in the present document support additional features not supported by the aforementioned formats, such as time-stamping and CAdES signing of multiple content and XAdES parallel signatures, that can be used in other contexts.

The present document defines baseline containers which provide 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.

The present document defines four levels of ASiC baseline containres addressing incremental requirements to maintain the validity of the containers over the long term, suitably profiled for reducing the optionality as much as possible, in a way that a certain level always addresses all the requirements addressed at levels that are below it.

ASiC containers specified in the two parts of this multipart deliverable aim at supporting containers in different regulatory frameworks.

The present document does not address the identification of the validation policy to be used for verifying a container that contains time-stamp assertions.
