Rambus has announced an 800G MACsec (Media Access Control security) offering for next-generation networking infrastructure.

The 800G MACsec solution delivers hardware-based, point-to-point security for 800 Gigabit Ethernet links and is a critical element of end-to-end network security.

Protecting data in motion, MACsec can identify and prevent security threats such as denial of service, intrusion, man-in-the-middle, passive eavesdropping and masquerading attacks.

With growing demand for low-latency communications to support real-time applications such as AI/ML inference, in-line, full-rate secure communication of data traffic with MACsec is imperative.

The device addresses this need with a hardware engine delivering MACsec security with no degradation to the speed of data transmission.

“Our 800G MACsec protocol engine leverages a scalable architecture that supports configurations of one to many ports with an aggregate bandwidth of up to 800 Gbps,” says Rambus vp Neeraj Paliwal, “this flexibility provides the benefit of limiting the silicon cost for security, while safeguarding required data communications.”

To speed the design process, the MACsec engine is delivered with a driver development kit (DDK). For customers building system-level solutions,

Rambus offers a MACsec Toolkit that implements the Port-based Network Access Control (PNAC) standard and facilitates development and testing of MACsec-compliant processing.

The product comprises a classifier and transform engine for deployment of the MACsec Layer 2 secure communication protocol. Implemented in hardware, this Rambus solution can deliver full line-rate MACsec security from 100G to 800G, making it an ideal choice for 800 GbE and 800GBASE-R.

Driven by the continued exponential growth in data traffic, 800 GbE is expected to be broadly deployed across hyperscale data centers, enterprises and carrier networks as well as in network-attached high-performance computing (HPC) and artificial intelligence (AI) / machine learning (ML).
