The Umbrella above the keys (silver and gold) in the place of the usual papal tiara is the symbol of the sede vacante, to represent that the Papacy, the position of the Bishop of Rome is vacant. A more complete version of the symbol is with the coat-of-arms of the Cardinal Camerlengo of the Holy Roman Church, who is currently the Cardinal Secretary of State, Cardinal Tarcisio Bertone of Italy.
The Cardinal Camerlengo is in charge of the events and governance of the Holy See, and also of the conclave during the sede vacante, until the new Pope is elected. He is also the one entrusted to seal the previous Pope’s private apartments and the destruction of the Ring of the Fisherman.
