Securing the slice management plane can be problematic when a slice traverses multiple authoritative domains.  Without compromising one domain to another, each domain must work together in a secure manner.  To this end SABRES uses Fully Homomorphic Encryption using Duality's Open Source Open FHE Library.

This effort is being lead by Duality PI David Cousins.
