A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Transport Layer Security WG of the IETF. Title : Guidance for External PSK Usage in TLS Authors : Russ Housley Jonathan Hoyland Mohit Sethi Christopher A. Wood Filename : draft-ietf-tls-external-psk-guidance-06.txt Pages : 16 Date : 2022-02-04 Abstract: This document provides usage guidance for external Pre-Shared Keys (PSKs) in Transport Layer Security (TLS) 1.3 as defined in RFC 8446. It lists TLS security properties provided by PSKs under certain assumptions, and then demonstrates how violations of these assumptions lead to attacks. Advice for applications to help meet these assumptions is provided. This document also discusses PSK use cases and provisioning processes. Finally, it lists the privacy and security properties that are not provided by TLS 1.3 when external PSKs are used.
