Layer 2: encryption on the Ethernet layer

The Ethernet frame is encrypted by inserting a secure header on the MAC layer (layer 2). The low overhead leads to only minor losses in data throughput and performance compared with layer 3 encryption, especially when encryption is hardware-based. The encryption is used for local and metro networks with high volumes of data and all applications due to the low latency. Encryption is standardised, but the key exchange is often specific to manufacturer.
  • Encryption with the aid of MACsec
  • Little impact on runtime
  • Little data overload

Actelis: QuFast SHDSL systems technology

Due to increasingly stringent security requirements, particular from network operators with critical infrastructure, encryption of the whole transmission path is becoming more and more interesting. Our solution, based on the QuFast SHDSL 600 EL range of devices, encrypts all traffic based on MACsec on layer 2. In this case, encrypted traffic is routed via the SHDSL or optical fibre line (up to 1GE wire speed). Therefore, the QuFast SHDSL 600 EL can also be used just as L2 encryption terminals/switches. For applications with SHDSL transmission, devices with 4 or 16 twisted pairs (can be bundled to increase the bandwidth) are available as desktop units or as top hat rails with up to four twisted pairs (two directions).
Characteristics:
  • MACsec encryption over SHDSL and/or optical fibre (also possible over L2 networks)
  • SHDSL solutions with 4 and 16 twisted pairs (can be bundled – 15 Mbit/s per DA)
  • Extensive L2 Ethernet features/QoS, QinQ, Ethernet measurements (ITU-T Y1564) etc.
  • Powerful SHDSL feature with bonding of up to 16 DAs
  • Optional SHDSL repeater solution available
  • Desktop units and top hat rails
  • Greater temperature range/industrial Ethernet
  • Graphical software and optional management system

DNWP: Dyna Wiz

Dyna Wiz is a strong IP-based access point for telecommunications networks in critical infrastructure. The compact design is ideal for hard-to-access or remote locations such as wind and solar farms.
