About R&S®SITLine ETH

The R&S®SITLine ETH is an ethernet encryption solution for up to 40 Gbit/s bandwidths. As a layer 2 encryptor, it protects companies and organizations against espionage and manipulation of data in motion that is transported via Ethernet over landline, radio relay or satellite links. The devices are approved by the German Federal Office for Information Security (BSI).

Features & benefits

High speed layer 2 encryption and low latencies

Encryption in real time: up to 40 Gbit/s bandwith

With R&S®SITLine ETH you get high-security combined with high-performance encryption:

  • Low latencies of up to 3 microseconds (3 µs)
  • Maximum bandwidth, up to 40 Gbit/s
  • Minimum overhead

State-of-the-art cryptographic methods and standards

Secure encryption and authentication

Securing point-to-point Ethernet lines and Ethernet VLANs:

  • Symmetric encryption: AES with 256-bit key, CFB (“zero overhead”), GCM, point-to-point and group encryption
  • Asymmetric: 257-bit ECC key (roughly corresponds to 3200-bit RSA key)
  • X.509v3 certificates for persons and equipment
  • Approved by the German Federal Office for Information Security (BSI) amd for use in in NATO and EU member countries 

Network management and monitoring

SNMP-based network management

Network settings on R&S®SITLine ETH devices can be configured using the simple network management protocol (SNMP):

  • The devices offer detailed data for monitoring as well as extensive diagnostic capabilities via SNMP
  • Either use any SNMP browser
  • Or use the R&S®SITLine Admin software delivered with the R&S®SITLine ETH for monitoring

Central Management

Central security management based on client-server architecture

R&S®SITScope is the central security management system for our Ethernet encryptors:

  • Based on client-server architecture
  • Acts as te certificate authority in a public key infrastructure
  • Available as pre-installed applicance
  • Or as seperate software for Windows and Linux
  • Smart card based tokens ensure secure handling of user and device certificates

Low energy consumption and low system costs

Significantly reduce operating costs while maintaining a high level of security

Minimal investment for installation and configuration is guaranteed:

  • Low space and energy costs through compact design and low module heigth
  • Low maintenance and service requirements because Ethernet operates independently of logical IP network
  • Bandwidth efficiency through group encryption: data is encrypted and transmitted only once
  • Fully automatically negotiate session keys required for operation
  • High availability as standard

Extreme environments

Robust and compact Ethernet encryption everywhere

For extreme environment, the R&S®SITLine ETH 50 is the right modell:

  • It is an exceptionally robust, compact (7.6“) Ethernet encryptor
  • With its extended operating temperature range (–20 °C to +70 °C) and fanless design, the encryptor can be used not just in non-climatized server rooms, but also on desktops and in vehicles
  • In case of emergency, the encryptor has a clear button to delete all security-relevant data on the device
