Arun Acharya, Anjali Singhai Jain, and Willem de Bruijn will give a talk on PSP.
PSP is a security protocol that incorporates lessons from experiences with currently deployed L2, L3 and L4 crypto protocols. PSP, originally developed and deployed at Google, shares many concepts with IPSEC and is encapsulated in UDP to avoid network issues with less common IP protocols.
PSP is purposely built to scale. It does not store an explicit SA in the ingress direction, but generates the ingress key on NIC from a device master key, combined with the SA SPI embedded in the packet. The full PSP Crypto Protocol Specification can be found at https://github.com/google/psp/doc
Arun, Anjali and Willem will give an introduction to PSP and then dig further into PSP NIC hardware offload
