I was shocked to read that, apparently, there is no key? https://security.stackexchange.com/questions/18225/mars-curiosity-rover-security https://security.stackexchange.com/questions/18225/mars-curi... I get the argument for why nuclear weapons aren't physically locked -- there's always people guarding them -- but not having security on a remotely operated billion-dollar device seems crazy to me, even if the technical barriers to establishing a link are high.

The person answering doesn't really comment on deep space missions, but I think the conclusion you draw (no encrypted link) is almost certainly right for Spirit and Opportunity, which were launched in 2003. The thinking used to be that a 70m radio dish (and all the accompanying deep knowledge about pointing, relative velocity, channel codes, etc.) would be enough of an obstacle. This thinking has definitively changed in the meantime.
