Seems they want to push everyone to RSA. I wonder why? The patent issue
is over so that can't be it.
I understood that it is believed that the discrete log problem is
possibly harder than factoring, since solving DL solves factoring but
not the other way around. Maybe the NSA has found a workable solution
for factoring but not for DL?
