Secret Key Oracle Clause Samples

Secret Key Oracle. When the adversary makes a query with information PID, the challenger chooses random numbers ρ and d, where ρ is as the secret key corresponding to PID. Then, computes D dP and queries xh5 h5(t, D, PID) through the list Lh5. Finally, sends <PID, D, ρ> to . = + = A
