The Server or client could terminate  the connection immediately when the  peer does not know the secret.  So in case of a  security Problem  the administrator could set an option for ssh and sshd like LockDownSharedSecret to  a random password and share it with other Trustworthy Administrators, who are  involved in fixing the problem.  My ideas how to use this shared secret:

How is this different to configuring /etc/securetty and tunnelling
Telnet over SSH Port Forwarding which I don't recommend BTW?
