ENTSOG, one of the most critical market players a key organisation in the EU for gas and electricity transmission, relies on the AS4 standard for interoperable data exchange. ENTSOG plans to release a new ENTSOG AS4 profile following the newly adopted eDelivery AS4 specificationseDelivey and ENTSOG collaborated in maintaining alignment when preparing updated versions of their AS4 profiles. |

To support secure communication and document exchange between these operators, ENTSOG developed and maintains a specialised AS4 usage profile tailored to the gas sector's unique needs. This profile, mandated by further legislation in 2015, specifies the use of the AS4 protocol for secure, standardised data exchange among transmission system operators (TSOs). While fully aligned with the eDelivery AS4 profile, the ENTSOG version includes specific configurations to meet the requirements of gas transmission operations, ensuring seamless integration and interoperability within the sector.
ENTSOG and eDeliverycollaborates collaborate closely together, ensuring permanent ongoing alignment in their use of the AS4 protocol. This approach highlights the advantages of using a common protocol across different domains, including enhanced security, reduced vendor lock-in, and streamlined interoperability.
Following the newly adopted updates to the adopted eDelivery AS4 profile specifications2.0, ENTSOG is is preparingto release a new version of its own AS4 usage profile in 2025.
ENTSOG’s Upcoming AS4 Usage Profile ENTSOG and eDelivery eDelivery
On 29–30 October 2024, ENTSOG hosted a workshop on Data Exchange and Cybersecurity in Brussels, bringing together experts and stakeholders to explore the latest updates, opportunities, and challenges in the energy sector. You can learn more about the event here.
One of the topics discussed was data exchange syntax and the modernisation of the cryptography used in the AS4 profile, focusing on the benefits and challenges of its rollout. The eDelivery team was invited to present therecent security updates to the eDeliveryAS4 profile, providing insights into the rationale behind these changes and explaining why corresponding updates are welcome in the ENTSOG AS4 profile.
Bogdan Dumitriu, the eDelivery project officer working for the European Commission, underscored thatthe primary motivation for these changes was following expert advice to stayup to date with technological advancements in cybersecurity. As cryptography and its use for internet security continue to evolve, it is crucial to align with state-of-the-art security mechanisms.
It was emphasised that while the current eDelivery profile remains secure, newer cryptographic standards, specifically elliptic curve cryptography, have now become the industry norm in modern applications and protocols. This necessitated the introduction of new algorithms and key types based on elliptic curve cryptography into the updated eDelivery profile.
