The regulation sets out reference standards and specifications in an Annex, adopting ETSI EN 319 421 V1.3.1 and ETSI EN 319 422 V1.1.1 with specific adaptations. Key requirements include that generation and protection of TSU keys must occur within secure cryptographic devices certified to Common Criteria EAL 4 or higher, EUCC EAL 4 or higher, or until 31 December 2030 FIPS PUB 140-3 level 3. The regulation mandates compliance with the European Cybersecurity Certification Group's Agreed Cryptographic Mechanisms for key generation, signature algorithms, hash algorithms, and key lengths. Network security requires vulnerability scans at least once per quarter and penetration tests at least once per year. Firewalls must block all non-required protocols. Qualified electronic time stamps must contain a qcStatements extension with the statement 'esi4-qtstStatement-1' not marked as critical. The regulation presumes compliance with relevant requirements of Regulation (EU) No 910/2014 if a trust service provider adheres to the Annex. The regulation entered into force on the twentieth day after publication in the Official Journal of the European Union and is binding in its entirety.",
