Can anyone give me some references for this problem?
Given a group G where computing Discrete Logarithms is hard. Let g and
h be two generators and m be any given element of G. Our goal is to try
to find two numbers (x, y) such that g^x.h^y=m. It is very likely that
this will have more than one solution for (x, y).
I want a proof that finding this type of collisions is considerably
easier than computing discrete logarithms.. (I need some sort of
metrics for the hardness of this problem in relation to the DLP).
As an extension of this question, what if we consider different
properties for G, say suppose DLP is hard but the DDHP is easy, in this
case is finding collisions any easier?
Thanks in advance
