Not sure what those keys are, but WE WANT'EM
The problem here, is that the Department of Homeland Stupidity doesn't really know what those keys are, but they heard the word "keys", and naturally they want them.
What it more worrisome, is that this organization (who has only NOW gotten it's first ever non-flunk grade on a FISMA audit), quite clearly does not have anything NEAR the IS/IT security systems that are needed for management of these keys.
What is even more worrisome, is that the Deparment of Homeland Stupidity quite clearly doesn't understand that International (as the Internet today is), means more than 50 states. I'm afraid that if this move is completed, then we will see another case where every government on the planet mandates their own security keys standard, instead of having a simple, global standard.
Now, I see several solutions for this problem, ranking from a simple "no, you can't have them" up onto "no, you can't have them because your ridiculous it standards make you a liability to the internet itself, and you are about to get disconnected for this very reason".
If these keys are to be handled by a central political power, the correct place for them would be the UN. Not, I repeat NOT the United States of America's "Department of Homeland Stupidity".
