Full title and description

STB DIN EN 13757-7:2018 — Communication systems for meters — Part 7: Transport and security services. This document defines transport-layer and security service mechanisms intended for use by metering communication systems (M‑Bus family) to protect meter-to-concentrator and meter-to-backend data exchange and to support fragmentation/reassembly, authentication and management of lower layers.

Abstract

This part of EN 13757 specifies transport and security services designed to provide secure communication capabilities by design for meters, sensors and actuators used in remote meter reading and related systems. It is intended to be used together with the lower-layer specifications in other parts of the EN 13757 series (EN 13757‑2 through EN 13757‑6) and includes authentication/fragmentation sublayer definitions, transport layer rules, management of lower layers and security-service definitions.

General information

• Publication date: EN publication: April 2018 (national adoption dates vary — e.g., Austria 2018-06-01, Czech adoption 2018-10-01).
• Publisher: CEN (European Committee for Standardization) / adopted and sold by national bodies (e.g., DIN editions in Germany).
• ICS / categories: 33.200; 35.100.10; 35.100.20 (telecontrol/telemetry, physical layer, data link layer).
• Edition / version: 2018 (original EN edition); revised and succeeded by a 2025 edition in the EN 13757 series.
• Number of pages: Approximately 91 pages in the EN publication (national HTML/PDF/printed copies report 91–100 pages depending on national forewords and pagination).

Scope

Specifies transport-layer primitives and security services for communication systems used in meter reading, tariff and load control. The standard defines a layered model including an Authentication and Fragmentation Layer (AFL), a Transport Layer (TPL), and management functions for lower layers; it also describes security services and a Security Information Transfer Protocol in normative annexes. The document is applicable where protection of consumer data and privacy is required and is intended to be used with EN 13757 lower-layer parts.

Key topics and requirements

• Layer model for transport and security services (AFL, TPL and management of lower layers).
• Authentication and Fragmentation Sublayer to support secure fragmentation and reassembly of meter payloads.
• Transport layer rules for segmented message delivery, sequencing and retransmission handling.
• Security services: confidentiality, integrity, authentication, message counters and related security state management.
• Normative annex defining a Security Information Transfer Protocol for provisioning and exchanging security-related data.
• Designed to be used in combination with other EN 13757 parts (wired/Wireless M‑Bus, application layer, relaying, local bus, etc.).

Typical use and users

Used by meter manufacturers, utility communication-system designers, system integrators, meter data management vendors and utility IT/security teams to design, implement and verify secure transport and messaging services for metering networks (including Wireless M‑Bus and Wired M‑Bus deployments). National standards bodies, certification organizations and compliance teams also refer to this part when evaluating security and privacy measures in metering solutions.

FAQ

Q: What is this standard?

A: EN 13757‑7:2018 defines transport and security services for meter communication systems — specifying how meter messages can be fragmented, transported and protected (authentication, integrity, confidentiality) and how security information can be exchanged.

Q: What does it cover?

A: It covers a layered transport/security model (AFL, TPL), message fragmentation and reassembly, transport primitives, management of lower layers and security services including a Security Information Transfer Protocol in a normative annex. It is intended to be used together with the other EN 13757 parts that specify lower layers and application protocols.

Q: Who typically uses it?

A: Meter manufacturers, utility communications and security architects, system integrators, test labs and certification bodies — anyone implementing or verifying secure metering communications based on the M‑Bus family.

Q: Is it current or superseded?

A: The 2018 EN edition has been superseded in national catalogs by a later EN 13757‑7 edition (publication cycle updated in 2025). National bodies list the 2018 edition as withdrawn and indicate the 2025 edition as the replacement; users should reference the 2025 edition for the most up‑to‑date normative text.

Q: Is it part of a series?

A: Yes — it is one part of the EN 13757 series covering communication systems for meters (parts cover data exchange, wired and wireless M‑Bus, relaying, local bus, transport/security, adaptation layer, etc.). Implementations normally combine multiple parts to achieve a complete solution.

Q: What are the key keywords?

A: Transport, security, authentication, fragmentation, M‑Bus, Wireless M‑Bus, meter communication, privacy, EN 13757.
