Designing Secure Datacenter Transport Protocol

Professor Michio Honda
Lecturer (Assistant Professor)
School of Informatics, University of Edinburgh

Datacenter operators and tenants need end-to-end encryption due to workload co-location and untrusted network infrastructure. The status quo is TLS/TCP and QUIC, but those are unfit for datacenters due to unsuitable abstractions and host software overheads. This talk presents our work on a secure datacenter transport protocol (SDP), which allows the use of legacy hardware offload for cryptographic operations available in commodity NICs, while using a new datacenter transport protocol as its basis, such as Homa, allowing operators that currently rely on TLS over TCP to adopt SDP without sacrificing hardware offloading opportunity.


Michio Honda is a lecturer (equivalent to assistant professor in US) in the School of Informatics at the University of Edinburgh. His best-known work is identifying TCP extensibility against middlebox interference and building the first TCP/IP network stack for persistent memory. His current research interests include networked storage systems and secure datacenter transport protocols. He is a recipient of IRTF Applied Networking Research Prize (2011), Facebook Research Award (2021) and Google Research Scholar Award (2022).
