I currently consider this broken since, turns out that XOR and permutation do not commute over each other, and anyway to get them do so so requires knowledge of the secrets to be transmitted in a way to the channel that lets attacks recover them.
The need for XOR can be removed, but then each half of the AONT(message) is exposed. I couldn't see a way around this. So even tho I'm sure there is a way to construct a secret exchange on insecure channel mechanism (probably using 3 pass) I do not see it right now.
