Re: [pkcs11] Groups - AES draft proposed changes. uploaded

Bob,

      

      For CK_GCM_PARAMS, the draft says that ulTagBits can have

      any value between 0 and 128. NIST Special Publication 800-38D

      says there are only seven valid values:

      32, 64, 96, 104, 112, 120, 128

      

      Oscar So suspected 0-128 might be wrong. I looked into it

      and believe it needs to be changed.

      

      CK_CCM_PARAMS also enumerates valid values for the length of the
      MAC,

      although they are specified in bytes rather than bits.

      AES changes to the draft from the working committee.

      

      The changes are quite small:

      1) just a clarification note in GCM and CCM descriptions. The note
      basically codifies what everyone seemed to agree as the actual
      semantic. Adding the note should alleviate future confusion.

      

      2) it actually removes CTS. At this point we don't have an
      agreement on CTS and the existing spec is agreed to be defective
      (we just don't agree on how it's defective).
