Abstract:
This document provides usage guidance for external Pre-Shared Keys
(PSKs) in Transport Layer Security (TLS) 1.3 as defined in RFC 8446.
This document lists TLS security properties provided by PSKs under
certain assumptions, and then demonstrates how violations of these
assumptions lead to attacks. This document discusses PSK use cases
and provisioning processes. This document provides advice for
applications to help meet these assumptions. This document also
lists the privacy and security properties that are not provided by
TLS 1.3 when external PSKs are used.
