Hi all,

I have submitted a new internet draft to introduce the SM cipher suites into TLS 1.3 protocol.


SM cryptographic algorithms are originally a set of Chinese national algorithms and now have been (or being) accepted by ISO as international standards, including SM2 signature algorithm, SM3 hash function and SM4 block cipher. These algorithms have already been supported some time ago by several widely used open source cryptographic libraries including OpenSSL, BouncyCastle, Botan, etc.

Considering TLS1.3 is being gradually adopted in China's internet industry, it's important to have a normative definition on how to use the SM algorithms with TLS1.3, especially for the mobile internet scenario. Ant Financial is the company who develops the market leading mobile app 'Alipay' and supports payment services for Alibaba e-commerce business. We highly are depending on the new TLS1.3 protocol for both performance and security purposes. We expect to have more deployment of TLS1.3 capable applications in China's internet industry by this standardization attempts.

It's very appreciated to have comments from the IETF TLS list :-)

Many thanks!
