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 present document, AdES digital signatures are meant when the term signature is being used.
NOTE 1: 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.
NOTE 2: The signature creation and validation procedures specified in the present document provide several
options and possibilities. The selection of these options is driven by a signature creation policy, a
signature augmentation policy or a signature validation policy respectively. Note that legal requirements
can be provided through specific policies, e.g. in the context of qualified electronic signatures as defined
in the Regulation (EU) 910/2014 [i.15].

Elektronski podpisi in infrastruktura (ESI) - Postopki za oblikovanje in validacijo digitalnih podpisov AdES - 1. del: Oblikovanje in validacija

Ta dokument določa postopke za:
• oblikovanje digitalnih podpisov AdES (določenih v standardih ETSI EN 319 122-1 [i.2], ETSI EN 319 132-1 [i.4], ETSI EN 319 142-1 [i.6]);
• ugotavljanje, ali je digitalni podpis AdES tehnično veljaven;
kadar koli digitalni podpis AdES temelji na kriptografiji javnih ključev in je podprt z digitalnimi potrdili javnih ključev. Za izboljšanje berljivosti tega dokumenta je namesto izraza »digitalni podpisi AdES« uporabljen izraz »podpis«.
OPOMBA 1: Uredba (EU) št. 910/2014 [i.15] opredeljuje izraze elektronski podpis, napredni elektronski podpis, elektronski žigi in napredni elektronski žig. Ti podpisi in žigi so običajno oblikovani s tehnologijo za digitalne podpise. Namen tega dokumenta je zagotavljanje podpore za Uredbo (EU) št. 910/2014 [i.15] za oblikovanje in validacijo naprednih elektronskih podpisov ter žigov, ko se uporabljajo kot digitalni podpisi AdES.
Ta dokument uvaja splošna načela, objekte in funkcije pri oblikovanju ali validaciji podpisov, ki temeljijo na omejitvah pri oblikovanju in validaciji podpisov, ter opredeljuje splošne razrede podpisov, ki omogočajo preverljivost v daljšem časovnem obdobju.
Področje uporabe ne zajema naslednjih vidikov:
• ustvarjanje in distribucija podatkov za ustvarjanje podpisa (ključi itd.) ter izbor in uporaba kriptografskih algoritmov;
• oblika, skladnja ali kodiranje vključenih podatkovnih objektov, še posebej oblika ali kodiranje za dokumente, ki jih je treba podpisati, ali za oblikovane podpise; in
• pravna razlaga podpisov, še posebej pravna veljavnost podpisa.
OPOMBA 2: Postopki za oblikovanje in validacijo podpisov, podani v tem dokumentu, zagotavljajo več možnosti. Razlog za številne možnosti so politika oblikovanja podpisov, politika razširitve podpisov ali politika validacije podpisov. Pravne zahteve so lahko podane v določenih politikah, npr. v kontekstu kvalificiranih elektronskih podpisov, kot je opredeljeno v Uredbi (EU) 910/2014 [i.15].
