New MACsec Device Delivers Increased Data Security for 400G Networks

SAN JOSE, Calif., May 23, 2019 (GLOBE NEWSWIRE) -- CREDO, a global innovation leader in Serializer-Deserializer (SerDes) technology which delivers high performance, low power connectivity solutions for 100G, 200G, 400G port enabled networks today announced 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 new family of devices addresses 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. The new MACsec device from Credo integrates the latest 256-bit AES technology, delivering increased data security to secure the critical high-speed data links between servers, switches and routers.

"Adding security functionality to our industry leading retimer and gearbox devices was a natural step for Credo," said Sandeep Shah, senior director of marketing at Credo. “We are able to deliver these solutions at low power in 28nm CMOS which translates into our customers ability to deploy systems with a competitive edge.”

The first member of the Credo 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.
