With the above claim, the algorithm B solves the DCDH problem with the probability [epsilon].
In the case that the both events happen, the algorithm B can solve the DCDH problem.
Thus we can conclude that if the DCDH assumption holds in G, there exists no algorithm which breaks the proof-unforgeability of our scheme with a nonnegligible probability.
The DDDH problem is weaker than DCDH, since if an adversary could solve the DCDH problem, he could solve the DDDH problem by computing [g.sup.x] to decide [g.sup.z] = [g.sup.y/x]; thus the DDDH assumption is stronger than the DCDH assumption.
DCDH assumption: Let B be an algorithm which has advantage
