Title: IETF encryption standards post-TLS 1.3
TLS is one of the most important security protocols online. It’s most famously used in web browsing, providing the S in HTTPS. After five years of discussions, debates, deployments, compromises, and ultimately industry consensus, in the Internet Engineering Task Force (IETF) standardized a new version of the protocol, TLS 1.3, published as RFC 8446 in late 2018. The improvements TLS 1.3 brings over previous versions are substantial, but it left several questions unanswered.
With TLS 1.3 complete, the IETF’s TLS working group has pointed its attention to new work. In this talk, I’ll explore how IETF standards are created, how to participate in the process, what new standards are currently under discussion, and how they relate to the future of security online. I’ll be exploring new proposals including Encrypted SNI, Delegated Credentials, Exported Authenticators, OPAQUE, and semi-static DH, and exploring some open research angles.
