feat: identity hiding in two stage process

Browse Source 
Changed identity hiding test to work as a two stage process where
participants with fresh secure secret keys communicate with each other
and other compromised participants. Then the attacker is asked to
identify the difference between two of the secure participants as on of
them acts as a responder.
