Electronic Signatures and Infrastructures (ESI); Procedures for Creation and Validation of AdES Digital Signatures; Part 1: Creation and Validation

The present document specifies procedures for:*- the creation of AdES digital signatures (specified in ETSI EN 319 122-1 [i.2], ETSI EN 319 132-1 [i.4], ETSI*EN 319 142-1 [i.6] respectively);*- establishing whether an AdES digital signature is technically valid;*whenever the AdES digital signature is based on public key cryptography and supported by public key certificates. To*improve readability of the document, AdES digital signatures are meant when the term signature is being used.*NOTE: Regulation (EU) No. 910/2014 [i.15] defines the terms electronic signature, advanced electronic*signature, electronic seals and advanced electronic seal. These signatures and seals are usually created*using digital signature technology. The present document aims at supporting the Regulation (EU)*No 910/2014 [i.15] for creation and validation of advanced electronic signatures and seals when they are*implemented as AdES digital signatures.*The present document introduces general principles, objects and functions relevant when creating or validating*signatures based on signature creation and validation constraints and defines general classes of signatures that allow for*verifiability over long periods.*The following aspects are considered to be out of scope:*- generation and distribution of Signature Creation Data (keys etc.), and the selection and use of cryptographic*algorithms;*- format, syntax or encoding of data objects involved, specifically format or encoding for documents to be*signed or signatures created; and*- the legal interpretation of any signature, especially the legal validity of a signature.
