Validation Authority

Qualified Trust Service Provider


Article 33.1 of Regulation (EU) 910/2014, establishes that the qualified validation service of electronic signatures, can only be done by a qualified trust service provider that meets the established requirements. 


ANF AC is Validation Authority, and together with @Firma (Government of Spain.), are the only entities authorized to issue validations that determine the validity status of the certificates issued by the different hierarchies of ANF AC.


The IETF approved manner of verifying the validity of a certificate is the Online Certificate Status Protocol (OCSP).


The OCSP service for validation of an electronic signature in origin, is a high availability online service. Complies with what is established in article 32.1 of Regulation (EU) 910/2014; in an automated manner, it includes the qualified electronic signature of ANF AC in its capability as a Validation Authority.

ANF AC is one of the few CAs that provides and offers, in free distribution, the necessary technology to verify the validity of the OCSP responses that it issues. Each OCSP has a unique qualified electronic certificate that identifies it. 
All international legislation agrees to determine the obligation of the CA to provide this service, and to impose on relying parties, consultation prior to accepting an electronic signature.  
ANF AC has an international network of permanently updated servers; this technical infrastructure allows us to provide this validation service in various modalities:
• Consultations via OCSP protocol.
• Consultations to the LDAP service.
• CRL´s download.
Developed in accordance with international standards:
• IETF RFC 5280 (Internet X.509 Public Key Infrastructure Certificate and CRL Profile) updated by 6818.
• IETF RFC 6960 (Online Certificate Status Protocol – (OCSP))
• IETF RFC 4511  Lightweight Directory Access Protocol (LDAP): The Protocol
