Transport Layer Security Cached Information Extension

Overview

RFC 7924, “Transport Layer Security Cached Information Extension”, is a Proposed Standard document published in July 2016 by S. Santesson, H. Tschofenig. The canonical text is published by the RFC Editor.

Abstract

Transport Layer Security (TLS) handshakes often include fairly static information, such as the server certificate and a list of trusted certification authorities (CAs). This information can be of considerable size, particularly if the server certificate is bundled with a complete certificate chain (i.e., the certificates of intermediate CAs up to the root CA).

This document defines an extension that allows a TLS client to inform a server of cached information, thereby enabling the server to omit already available information.

What “Proposed Standard” means

An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
