That is, if we set up the equation $x = A/B$, then this should be equivalent to $xB = A$, which is the discrete log of A to the base B - hence, it is well defined (if somewhat intractable to compute). Of course, this has nothing to do with the paper, which is written in multiplicative notation... | |
