ShangMi Cipher Suites for TLS 1.3

Overview

RFC 8998, “ShangMi Cipher Suites for TLS 1.3”, is an Informational document published in March 2021 by P. Yang. The canonical text is published by the RFC Editor.

Abstract

This document specifies how to use the ShangMi (SM) cryptographic algorithms with Transport Layer Security (TLS) protocol version 1.3.

The use of these algorithms with TLS 1.3 is not endorsed by the IETF. The SM algorithms are becoming mandatory in China, so this document provides a description of how to use the SM algorithms with TLS 1.3 and specifies a profile of TLS 1.3 so that implementers can produce interworking implementations.
