Yes, but using that key on a computer that he does not trust is NOT
"keeping the key secure".
To answer the OP, there is no straightforward way to connect to your
machine from a computer that you don't trust and still be safe. You
can try port-knocking which will slow down an attacker until he
figures out that is what you are doing from the compromised machine.
You might also have better luck with one-time passwords or one-time
Or, if it is possible, set up a web interface to whatever you want to
control on your home computer and do it in a browser. That will limit
the expose of the machine to whatever services you are controlling
from the browser.
