note right of N : via tcp/ip over ssl while starting the new node. 
L --> N : FindCoordinatorResponse(c) this will have publickey for coordinator

Restart of-> locatorC will use saved publickey in view.dat file, to encrypt FindCoordinator request over udp.
We will prefix its publicKey with FindCoordinator message, so that member can decrypt findCoordinator request.
end note
