• Opcodes and encodings proposed
• Instruction extensions (instruction groupings) proposed
• Submitted to review task group
• The Bit-Manipulation shared subsets are being reviewed first as part of Bit-Manipulation specification review
  • Proposed as Zkg Zbkc (clmul) Zbkx (xperm) and Zkb Zbkb (other specific crypto-required bit-manipulation commands)
• The Proposed Scalar Crypto-unique subsets are next in line for review:
  
  • K (Krypto): 
    • Zkn (full NIST Suite):  ZKne (NIST encrypt suite), ZKnd (NIST decrypt suite), ZKnh (NIST hash suite), ZkgZbkc, Zbkx, Zkb Zbkb (see above)
    • Zkr (random entropy source)
  • Zks (full ShangMi Suite):  Zksed (SM4 encrypt/decrypt suite), Zksh (SM3 hash suite), Zbkc, ZkgZbkx, Zkb Zbkb (see above)

• OpCode and Consistency Review page
• What's next:  Respond to OpCode and Consistency Review comments, once available, and achieve consensus on any changes.
• We need to discuss the aes32* and sm4* rt encodings.
  
  • Comments from others and Andrew particularly suggest that having distinct rd/rs1/rs2 is acceptable and that we over-estimated the importance of minimising encoding cost.
  • We will likely be reverting to the original form of these instructions, with separate rd/rs1/rs2 before public review.
