The RISC-V Cryptography Extensions Task Group has opened a public review period on a raft of instruction set extensions, ahead of their planned adoption as official standards – including instructions for AES encryption and decryption and the SM3 hash and SM4 block cipher.
“This specification has been developed by the RISC-V Cryptography Extensions Task Group under the governance of the Unprivileged and the Security Committees,” says Richard Newell, chair of the RISC-V Cryptography Extensions Task Group and an associate technical fellow at Microchip.
