(15 pоints) (See scheme described аbоve) The cоmpаny hired а cryptography consultant to assess security, and she said that  is IND-CCA assuming is IND-CCA and justified her statement with the following. "For any efficient IND-CCA adversary attacking , we can construct an efficient IND-CCA adversary attacking as follows: Analyzing the above construction we see that the IND-CCA advantages of both attackers are equal, because the simulation is perfect, i.e., 's view in the experiment simulated by is exactly like in its IND-CCA experiment; and wins whenever wins. Clearly, is efficient whenever is efficient:
