Was ist AS4? AS4 ist ein internationaler Kommunikationsstandard für sicheren, zuverlässigen Datenaustausch — entwickelt für hochsichere Branchen (Banken, Regierungen, Energie). AS4 ersetzt die alte Marktkommunikation (z. B. über E-Mail + EDIFACT) durch ein modernes, verschlüsseltes, zertifikatsbasiertes Protokoll. Was ist MaKo2025? MaKo2025 steht für Marktkommunikation 2025 und ist eine umfassende Überarbeitung der Kommunikationsprozesse zwischen Marktteilnehmern der Energiewirtschaft (VNB, MSB, GWA, Lieferanten, Bilanzkreise usw.). Die Bundesnetzagentur und BSI wollen damit Prozesse vereinheitlichen, automatisieren und digitalisieren. Übersichtsgrafik was ist was See more
