Ultra Ethernet Security (UET‑TSS) Tailored For AI And HPC

The article discusses the development of Ultra Ethernet Security (UET‑TSS) tailored for AI and HPC systems. Traditional Ethernet security mechanisms were not designed for the scaling and trust assumptions of next‑generation networks supporting AI and high‑performance computing (HPC). The Ultra Ethernet Consortium (UEC) introduced the Ultra Ethernet Specification 1.0 to define a new Ethernet‑based transport protocol for AI and HPC networks, focusing on security as a key architectural concern. The Ultra Ethernet Transport Security Sub‑layer (UET‑TSS) was created to address the security challenges posed by the architectural shift in AI/HPC clusters. Rambus introduced two new solutions, UET-TSS-IP-69 and UET-TSS-IP-369, to secure UET transport protocol with TSS for SmartNICs and NIC chiplets.
