What do you mean when you say you don’t want to “join a ‘ring’ of people” who say controversial stuff? That doesn’t line up with the (admittedly weak) understanding of the protocol that I’m getting from wikipedia. Someone just assembles a list of public keys at their leisure, and uses all of them plus their own, to sign a message. The only way to not be implicated is to never have a publicly available key, right?
Uh, maybe I misunderstood it, but reading the Wikipedia article I got an impression that “ring signature” is a signature shared by group of people. Did I miss the point?
You need to have a private key to sign, otherwise it would be useless as a “signature”.
For signing (in the non-ring case), you encrypt with your private key and they decrypt with your public key, whereas in normal encryption (again, non-ring) you encrypt with their public key and they decrypt with their private key.
