As many people know, Chinese government regulators are now mandating use of SM2, SM3 and SM4 in critical systems, including automobiles, avionics, power systems, and communication systems. Since many of our customers are multi-nationals that do business in China, they have been requesting the addition of these algorithms in wolfSSL products.
Today we are about to release our supported versions of SM2, SM3, and SM4, with the intention to release the ZUC stream cipher at some point this year to completely satisfy SM9. We are also in contact with labs regarding support of OSCCA certification at some point in the future.
This is really great news for our customers selling into Chinese markets!
For those readers considering using wolfSSL products, here’s some additional notes:
- The SM Ciphers will be fully supported in wolfSSL’s TLS 1.3 implementation.
- wolfSSH, wolfBoot and our other products will support ShangMi ciphers.
- ARM, Intel, and RiscV assembly is in the works for our SM implementations for maximum performance.
- We will continue to support bare metal for ZUC, SM2, SM3, and SM4.
- True to form, we have maximized performance and minimized size, so the ShangMi algorithms will work well for embedded systems use cases on a wide variety of microcontrollers (MCU’s). They will be available for all of the MCU silicon that we currently support, including STM32, NXP i.MX, RISC-V, Renesas RA, RX, and Synergy, Nordic NRF32, Microchip PIC32, Infineon Aurix, TI MSP, and many others.
- Our GPLv2 licensed versions of the SM ciphers will be made available on GitHub and for download.
Commercially licensed versions are available.
