European Commission Implementing Decision 2015/1506 of 8 September 2015 laid down specifications relating to formats of advanced electronic signatures and advanced seals to be recognised by public sector bodies pursuant to Articles 27 and 37 of the eIDAS-regulation.
It can be advantageous to use detached signatures because it prevents unauthorized modifications to the original data objects.
[2] One of the most widespread deployments of the ASiC standard is the Estonian digital signature system with the use of multiplatform (Windows, Linux, MacOS (OSX)) software called DigiDoc.
This container type will allow additional signatures to be added in the future to be used to sign stored file objects.
An ASiC-E container could be designed to prevent this modification or allow its inclusion without causing damage to previous signatures.
Additional elements may be within its META-INF folder and requires the use of “SignedData” variable to include certificate and revocation information.
