Hi there all,

I'd appreciate it if folk could have a look at this draft and provide
any feedback.
I'm not sure that SAAG is the right place for it, but I couldn't think
of anywhere better.

https://tools.ietf.org/html/draft-wkumari-owe-01


Note that this is NOT intended to be the be all and end all of secure
wireless, it is simply intended to make open wifi suck somewhat less.
We are not claiming great security (the WPA2 4-way handshake
significantly limits what can be achieved), and so much of the draft /
idea is making sure that users do not get a false (or any) sense of
security - this should be transparent to them.

We also want it to be *really* simple, so that commodity CPE vendors
will include "support" (basically a flag in the beacon) - this removes
other solutions like .1X, etc.

Appreciate your time,
W

I don't think the execution is relevant when it was obviously a bad
idea in the first place.
This is like putting rabid weasels in your pants, and later expressing
regret at having chosen those particular rabid weasels and that pair
of pants.
