Then we can construct an algorithm B that solves the DCDH problem on G.
Given (g,[ga],[gb]) as an input for the DCDH problem, the algorithm B simulates the challenger and interacts with the forger [A2] in the proof-unforgeability game.
Given an instance (g, [g.sup.a], [g.sup.b]) [member of] G of the DCDH problem, the algorithm B simulates the challenger and interacts with the forger [A.sub.3] in Game III.
The DCDH problem is as follows: given (g, [g.sup.x], [g.sup.y]), where x, y [member of] [Z.sub.q], compute [g.sup.y/x].
DCDH problem: Given g, [g.sup.[alpha]], [g.sup.[beta]] in G for unknown [alpha], [beta] [member of] [Z.sup.*.sub.q], compute [g.sup.[alpha]/[beta]].
