Communication protocol and encryption
by GasTerra B.V.
Abstract
Market area operators are implementing changes to the AS2 protocol and forcing market participants to adapt their IT-systems to these changes. Market participants have implemented AS4 according to the NC Interoperability. AS4 contains the requested functionality and if market area operators implement it in accordance with NC interoperability, the change to AS2 and the related efforts and costs for market participants would be obsolete. However, market area operators put forward an argument that they do not have to comply with the NC Interoperability.

Reported issue
Currently market area operators and market participants communicate via AS2-protocol. Market area operators are implementing changes to the algorithm and encryption of the AS2 protocol in order to achieve a functionality which is already available within the AS4-protocol. Market participants have already implemented and are able to communicate via AS4. The NC Interoperability (Article 21.2) specifically provides for the use of the AS4 protocol. If market area operators implement the AS4 protocol in accordance with NC interoperability, the change to AS2 and the related efforts and costs for market participants would be obsolete. However, market area operators put forward an argument that they do not have to comply with the NC Interoperability and are thus forcing market participants to invest in a new IT interface and maintain it for the future until the change to AS4 is made.

Public Consultations on Communication protocol and encryption
Solution
The consultation process demonstrated that stakeholders are supportive of the extension of the data exchange provisions in the INT NC to virtual trading points. Therefore, ACER and ENTSOG propose an amendment of the INT NC to achieve this as detailed in the attached slide pack. It is proposed to amend Article 1(2), 20 (1), 20 (2) and 23 (1) to extend the scope to virtual trading points and, subject to NRA decision, to points other than interconnection points (e.g. storage and LNG).
As for encryption algorithms, ENTSOG has established a dialogue with the German NRA (BNetzA) and the German institute for IT security (BSI) to find a possible long-term solution for document-based data exchange.
