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.

Submitter's message
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).
