Joe,
The wording on the nonce length in draft-touch-tcpm-experimental-options
may be a little bit unclear ("it MAY be as few as 16 bits if desired").
Does that statement intend to say something like "MUST NOT be shorter
than 16 bits long"? Or shall even a nonce of length 0 be allowed,
provided that there are additional security mechanism such as checksums
or digital signatures? In the latter case, existing use of the
codepoints without nonce could be compliant to the recommendation,
provided that there are other means to detect false positives.
As a side note, I guess that the numbers "245 and 255" in the second
paragraph are wrong. This should refer to 253 and 254, right?
Michael (as individual)
