Electronic Signatures and Infrastructures (ESI); CAdES digital signatures; Part 2: Extended CAdES signatures

Scope

The present document specifies CAdES digital signatures. CAdES signatures are built on CMS signatures [i.9], by
incorporation of signed and unsigned attributes, which fulfil certain common requirements (such as the long term
validity of digital signatures, for instance) in a number of use cases.
The present document specifies a number of CAdES signature levels addressing incremental requirements to maintain
the validity of the signatures over the long term, in a way that a certain level always addresses all the requirements
addressed at levels that are below it. These CAdES extended signatures a higher degree of optionality than the CAdES
baseline signatures specified in ETSI EN 319 122-1 [1].
Procedures for creation, augmentation, and validation of CAdES digital signatures are out of scope and specified in
ETSI EN 319 102-1 [i.5]. Guidance on creation, augmentation and validation of CAdES digital signatures including the
usage of the different properties is provided in ETSI TR 119 100 [i.4].
The present document aims at supporting digital signatures in different regulatory frameworks.
NOTE: Specifically but not exclusively, CAdES digital signatures specified in the present document aim at
supporting electronic signatures, advanced electronic signatures, qualified electronic signatures,
electronic seals, advanced electronic seals, and qualified electronic seals as per Regulation (EU)
No 910/2014 [i.8].
