Greg, assorted folks noted, way back when, that Skipjack looked a lot
like a stream cipher. Might it be vulnerable?
I'm still absorbing Adi's new ideas, and I haven't looked at this in any
detail, so anything I say should be taken with an enormous grain of salt.
But,

Yes, the program chair and committee did a great job. Whatsisname? Oh,
yeah, David Wagner.
Greg.
Yes, of course Adi is correct, but I blame you for reading what I wrote
and not what I meant... :-)

Hmmm, interesting. I'm getting increasingly closer to talking through my
hat, but...
Skipjack has an 8x8 S-box, so by definition the maximum degree

what about RC4, the most important stream
cipher in the Internet world?
So I cornered Adi for a while. Of course he'd thought of almost
everything I wanted to ask.
You're not the first to think of RC4 (I confess I wasn't either). No, if
you try to express shuffling as a
