How does this handle SSH session re-keying, does that need further authentication from the device? openssh does this pretty infrequently, I can't immediately remember if that needs participation with the asymmetric key or not. ED: Seems it's just as if you re-did the cipher negotiation, so no asymmetric interaction.
