Locking Out the KGB

The Puzzler

RAY: This came from a fellow named Michael Wortman and it is from my lock and key series, which I just started today. I had to add a few things to make it sufficiently bogus.

Imagine you have a friend who lives in Russia where the KGB spies on everyone and everything and you want to send a valuable object to this friend. So you have a box which is more than large enough to contain the object and you have several locks with keys.

Now this box, I suppose you could call it a strongbox, has a lock ring which is more than large enough to have a padlock attached to it. In fact it's large enough to accommodate several locks. But your friend does not have the key to any lock that you have. Now you can't send a key in the mail because the KGB will intercept it and they will copy it. And you can't not lock the box, because the object is very valuable. So you have to send it through the mail. You can't hand deliver it. You want to lock it so that your friend can open it, but the KGB can't.

The question is, how would you do it?
