MACs Boost Data Security For 400G Networks

CREDO launches what it’s calling the industry’s most comprehensive family of PHY devices supporting the IEEE 802.1AE media access controller security (MACsec) and internet protocol security (IPSec) standard for 10G through 400G port interconnects. The devices address security requirements for various Ethernet data link configurations in next generation high-speed, mission-critical network infrastructure that includes enterprise, cloud-scale data center, and service provider networks for both commercial and government deployments. Credo’s latest MACsec device integrates state-of-the-art 256-bit AES technology to secure the critical high-speed data links between servers, switches and routers. 

The first member of the MACsec family, the CMS42550, is available as a pin-compatible upgrade to the production shipping 400G gearbox, the CMX42550KP, which has been deployed in hyperscale data centers. The second member of the family, the CMS50216, doubles the MACsec throughput to 800G. Other family features include:

  • Supports MAC rates of 10G, 25G, 40G, 50G, 100G, 200G and 400G
  • 400G MACsec Gearbox / Retimer (CMS42550)
  • 800G MACsec Retimer (CMS50216)
  • Full MACsec Support
  • 512 Full SecY support
  • IEEE 802.1AE compliant
  • IEEE 802.1AEbn compliant (256-bit key)
  • IEEE 802.1AEbw compliant (extended packet numbering)
  • All cipher suites supported (GCM-AES-128/256, GCM-AES-XPN-128/256)
  • MACsec extensions: passing up to 4 x VLAN tags in clear
  • Full IPsec Support
  • Support for IP/UDP/ESP headers
  • Support for packets with VLAN tags
  • Advanced IPsec features for Enterprise, Data Center and Telecom applications
  • Each port can be configured to MACsec, IPsec or Bypass mode
  • Low power 28-nm CMOS
