Our partner MTG provides the right components to meet the increasing security requirements in the energy market. The legal requirements elevate data communication to a new level of security, ensuring the confidential and secure exchange of information and control commands between all market participants. The Smart Meter PKI in accordance with BSI TR-03109 delivers the security infrastructure that enables smooth and protected communication between smart metering systems (SMGW) and the relevant market roles. MTG supports all BSI TR-03109-regulated processes – from the production and management of smart meter gateways to CLS control, AS4-based MAKO, and communication via the BDEW Web API.
1. Smart Meter PKI: We offer the DARZ GmbH (CA) as a managed service. The MTG Metering CA is also deployed in on-premise solutions at leading energy suppliers. Through this service, all required certificate types are provided for actors in the designated market roles.
2. Encryption & communication: The MTG CryptoController delivers quick, easy-to-use, and legally compliant security. Based on a unified, high-performance security infrastructure, it can be flexibly applied for:
- SMGW manufacturer (GWH) for equipping initial production certificates,
- Gateway Administrators (GWA) for the secure administration of SMGW,
- smart meter data reception as a passive EMT (pEMT),
- CLS management as an active EMT (aEMT) with our innovative MTG Mehrwert-Konnektor
- AS4-based market communication (MAKO)
- and secure communication via the BDEW Web API for 24-hour supplier change (LFW24) and the transmission of switching commands.
3. CLS devices: The MTG CLS Stack was specifically designed to help IoT manufacturers quickly and easily connect their devices to smart meter gateways (SMGW) in a fully compliant manner. This powerful solution simplifies integration into the smart metering market and provides manufacturers with a secure, future-proof foundation for device communication.
4. Hardware Security Modules (HSM):Our partner MTG integrates the required HSMs in a vendor-independent manner to meet the highest security standards and comply with all legal requirements. This ensures that your IT infrastructure meets the strictest regulations while providing reliable, legally compliant security.
