What about launching a probe that echoes any signals it gets? If it were sufficiently far away, one could send it the private key and destroy the local copy. No

What about launching a probe that echoes any signals it gets? If it were sufficiently far away, one could send it the private key and destroy the local copy. Nobody's going to leave from Earth (or wherever) and catch up to your private key!

- pavel_lishin 13y agoSince you're launching the probe well in advance of sending out the key, a sufficiently well-funded and a paranoid party could send a probe that just trails yours, intercepting your signal and beaming it back to the party in question (encrypted with their private key, of course.)
