Abstract

We introduce Faust, a solution to the "anonymous blacklisting problem:" allow an anonymous user to prove that she is authorized to access an online service such that if the user misbehaves, she retains her anonymity but will be unable to authenticate in future sessions. Faust uses no trusted third parties and is one to two orders of magnitude more efficient than previous schemes without trusted third parties. The key idea behind Faust is to eliminate the explicit blacklist used in all previous approaches, and rely instead on an implicit whitelist, based on blinded authentication tokens.
