Abstract:
Anonymity can give users the license to misbehave. BLACR is the first scheme to generalize “reputation based anonymous blacklisting”, where users can be blocked based on their overall behavior while maintaining their privacy. BLACR also uses an “express lane” technique to greatly speed up authentication and make such schemes practical.
