Play the recording: Designing Transport-Level Encryption for Datacenter Networks (SDP)

Why: Encryption for next-gen DC transports (NDP, Homa) is where DC transport security is heading; touches both fabric and security.

What: A protocol design integrating data encryption into emerging datacenter transports with TLS-style NIC offload.

How: Supports NIC offloading modeled on TLS-over-TCP, a native protocol number alongside TCP/UDP, and a message-based abstraction for low-latency parallel RPCs. (Short paper — abstract is thin; treat as a direction-setter, not a finished design.)

Where applicable: General DC-transport proposal; early-stage.
