Hi,
I went to the IPR WG meeting on Monday and learned lots. But enough about
me...
The current [TRANS] document references Arcfour as an acceptable
algorithm. It also references RC4 in a somewhat oblique way as follows:
The "arcfour" is the Arcfour stream cipher with 128 bit keys. The
Arcfour cipher is believed to be compatible with the RC4 cipher
[SCHNEIER]. Arcfour (and RC4) has problems with weak keys, and
should be used with caution.
The parts about RC4 sound editorial to me. I also don't think that the
document should say that there is a "belief" in compatability; they either
are provably compatible, or the document should remain silent on that
point.
