In this lecture, we present a practical and provably secure (authenticated) key exchange protocol and a password authenticated key exchange protocol, which are based on the learning-with-errors problems. These protocols are conceptually simple and have strong provable security properties.
This type of new construction started in 2011-2012, and these protocols are shown indeed practical. We will explain that all the existing LWE based key exchanges are variants of this fundamental design.
