Ethernet has become the ubiquitous communication solution from the desktop to the carrier network. Industries including aerospace, automotive, manufacturing and utilities are adopting Ethernet, replacing legacy networking and communication methods. Applications in this broad market space require deterministic behavior of the Ethernet link that is implemented with Time-Sensitive Network (TSN) standards: traffic shaping, priority queues, preemption, and time synchronization. Protecting TSN traffic with MACsec requires proper interoperation between these standards. Rambus has introduced the MACsec-IP-161, ideal for securing traffic at rates from 1G to 50G between TSN-capable Ethernet devices. The MACsec-IP-161 is the newest member of Rambus’ industry-leading portfolio of MACsec engines for Ethernet security up to 800G data rates.
