What is BS EN 13757-7- Transport and security services about?
BS EN 13757-7 specifies Transport and Security Services for communication systems for meters.
BS EN 13757-7 specifies secure communication capabilities by design and supports the building of a secure system architecture.
BS EN 13757-7 is applicable to the protection of consumer data to ensure privacy.
Who is BS EN 13757-7- Transport and security services?
BS EN 13757-7- Transport and security services is useful for:
- Information technology industry
- Businesses dealing with communication system for meters
- Transport and security services departments
- Consumer data protecting agencies
Why should you use BS EN 13757-7- Transport and security services?
BS EN 13757-7 belongs to the EN 13757 series, which covers communication systems for Meters. The meter communicates with one (or occasionally several) fixed or mobile communication partners which again might be part of a private or public network. These further communication systems might use the same or other application layer protocols, security, privacy, authentication, and management methods.
The security policy is under the responsibility of organizations according to their business processes. The major elements of a security policy, in combination with rules, will determine the overall security that is achieved. The security policy defines goals and elements of the system to be supported by organizational policy and technical implementations of security services. BS EN 13757-7 provides security services supporting those policies when implemented.
BS EN 13757-7 provides a set of security services allowing the design of a secure system, which enables you to resist attacks within the lifetime of the meter.
The limitation to symmetrical cipher methods for data transmission allow energy and memory efficient solutions. This is advantageous for long-term battery-operated meters. BS EN 13757-7 enables you to ensure well integration of unidirectional meter communication. Services like key derivation and key distribution solves the conflict between short key lifetime and long lifetime of a meter.
What’s changed since the last update?
BS EN 13757-7:2018 together with EN 13757-3:2018 and CEN/TR 17167:2018 supersedes EN 13757-3:2013. BS EN 13757-7:2018 includes some technical changes with respect to EN 13757-3:2013.
These include:
- New security modes (formerly “encryption mode”) 7, 8, 9 and 10 supporting encrypted and authenticated messages have been added
- Support of Key Derivation Function for the generation of ephemeral keys
- New Authentication and Fragmentation Layer has been introduced
