Overview

SIST EN 319 412-4 V1.4.1:2025 defines a standardized certificate profile for web site certificates used in electronic signatures and trust infrastructures, with a particular focus on certificates accessed via the TLS protocol. This standard, published by the Slovenian Institute for Standardization (SIST) and aligned with ETSI EN 319 412-4, ensures web site certificates meet harmonized content and interoperability requirements.

By building on widely recognized frameworks such as the CA/Browser Forum Baseline Requirements and Extended Validation (EV) guidelines, as well as other standards in the ETSI ESI portfolio, this document clarifies requirements for certificate content and some aspects of certificate processing, facilitating secure online transactions and electronic trust services for both legal and natural persons.

Key Topics

• Web Site Certificate Profile: Specifies the structure, content, and necessary attributes required for TLS-based web site certificates, enabling interoperability across trust services and browsers.
• Reference to Established Baselines: Leverages the CA/Browser Forum’s baseline requirements and EV guidelines to ensure compliance with global best practices for certificate issuance and management.
• Applicability: The profile is relevant for certificates issued to both legal persons (organizations, companies) and natural persons (individuals), with tailored references to EV and baseline requirements as appropriate.
• Certificate Content Requirements: Focuses on mandatory and recommended fields, extensions, and identifiers, particularly for interoperability and accurate subject identification.
• EU Qualified Certificate Support: Addresses requirements for qualified certificates under Regulation (EU) No 910/2014 (eIDAS), ensuring web site certificates meet European legal mandates for trust services.
• Interoperability: Facilitates compatibility across different systems and jurisdictions by referencing both European regulations and international specifications such as ITU-T X.509 and ISO/IEC 9594-8.

Applications

SIST EN 319 412-4 V1.4.1:2025 is designed to improve trust in digital communications and electronic transactions through standardized web site certificates. Key application areas include:

• Secure Online Transactions: Ensuring web sites deliver secure, authenticated communication channels for online banking, e-commerce, and government services.
• Electronic Signature Infrastructures: Supporting legally binding electronic signatures by aligning web site certificate content with international and European requirements.
• Trust Service Providers: Assisting service providers in issuing certificates that comply with regulatory and industry expectations, notably for EU qualified certificates.
• Web Browsers and Servers: Enabling browsers and web servers to recognize and correctly process web site certificates, enhancing end-user security and trust.
• Cross-Border Interoperability: Supporting harmonized certificate profiles for multinational use, facilitating digital services across the EU and internationally.

Related Standards

Implementing SIST EN 319 412-4 V1.4.1:2025 typically involves reference to related standards and guidelines, including:

• ETSI EN 319 412-1: Overview and common data structures for certificate profiles.
• ETSI EN 319 412-2 and EN 319 412-3: Profiles for certificates issued to natural and legal persons.
• ETSI EN 319 412-5: Requirements on QCStatements for qualified certificates.
• ETSI EN 319 411-1 & EN 319 411-2: Policy and security requirements for trust service providers, including provisions specific to EU qualified certificates.
• CA/Browser Forum Baseline Requirements: Global best practices for the issuance and management of publicly trusted TLS server certificates.
• CA/Browser Forum Extended Validation Guidelines: High-assurance guidelines for extended validation certificates.
• IETF RFC 5246: Underlying specification for the TLS protocol.
• Regulation (EU) No 910/2014 (eIDAS): Legal foundation for electronic identification and trust services in the EU.

Practical Value

SIST EN 319 412-4 V1.4.1:2025 is essential for organizations seeking to secure their web presence, comply with international and regional regulations, and foster trust in electronic transactions. Adoption ensures that web site certificates are both robust and interoperable, supporting seamless and secure digital services across borders and industries.

Introduction
ITU and ISO issued standards for certification of public keys in Recommendation ITU-T X.509 | ISO/IEC 9594-8 [i.4]
which are used for the security of communications and data for a wide range of electronic applications.
Regulation (EU) No 910/2014 [i.3] of the European Parliament and of the Council of 23 July 2014 on electronic
identification and trust services for electronic transactions in the internal market and repealing
Directive 1999/93/EC [i.2] defines requirements on specific types of certificates named "qualified certificates".
Implementation of the Directive 1999/93/EC [i.2] and deployment of certificate infrastructures throughout Europe as
well as in countries outside of Europe, have resulted in a variety of certificate implementations for use in public and
closed environments, where some are declared as qualified certificates while others are not.
The CA/Browser Forum released the Extended Validation Certificate Guidelines [3] and the Baseline Requirements for
the issuance and management of publicly trusted TLS/SSL certificates [2] to mitigate website spoofing attacks.
The present document aims to maximize the interoperability of systems issuing and using certificates both in the
European context under the Regulation (EU) No 910/2014 [i.3] and in the wider international environment, also by
meeting requirements from CA/Browser Forum.

1 Scope
The present document specifies a certificate profile for web site certificates that are accessed by the TLS protocol [i.1].
The profile defined in the present document builds on the CA/Browser Forum Baseline requirements [2], Extended
validation guidelines [3] and other parts of the present multi-part deliverable.
The present document focuses on requirements on certificate content. Requirements on decoding and processing rules
are limited to aspects required to process certificate content defined in the present document. Further processing
requirements are only specified for cases where it adds information that is necessary for the sake of interoperability.
This profile can be used for legal and natural persons. For certificates issued to legal persons, the profile builds on the
CA/Browser Forum EV Profile [3] or baseline requirements [2]. For certificates issued to natural persons, the profile
builds only on CA/Browser Forum baseline requirements [2].

Introduction
ITU and ISO issued standards for certification of public keys in Recommendation ITU-T X.509 | ISO/IEC 9594-8 [i.4]
which are used for the security of communications and data for a wide range of electronic applications.
Regulation (EU) No 910/2014 [i.3] of the European Parliament and of the Council of 23 July 2014 on electronic
identification and trust services for electronic transactions in the internal market and repealing
Directive 1999/93/EC [i.2] defines requirements on specific types of certificates named "qualified certificates".
Implementation of the Directive 1999/93/EC [i.2] and deployment of certificate infrastructures throughout Europe as
well as in countries outside of Europe, have resulted in a variety of certificate implementations for use in public and
closed environments, where some are declared as qualified certificates while others are not.
The CA/Browser Forum released the Extended Validation Certificate Guidelines [3] and the Baseline Requirements for
the issuance and management of publicly trusted TLS/SSL certificates [2] to mitigate website spoofing attacks.
The present document aims to maximize the interoperability of systems issuing and using certificates both in the
European context under the Regulation (EU) No 910/2014 [i.3] and in the wider international environment, also by
meeting requirements from CA/Browser Forum.

The profile defined in the present document builds on the CA/Browser Forum Baseline requirements [2], Extended
validation guidelines [3] and other parts of the present multi-part deliverable.
The present document focuses on requirements on certificate content. Requirements on decoding and processing rules
are limited to aspects required to process certificate content defined in the present document. Further processing
requirements are only specified for cases where it adds information that is necessary for the sake of interoperability.
