In this game, a client undertak...

Byzantine quorum systems have been proposed that work properly even when up to f replicas fail arbitrarily. However, these systems are not so successful when confronted with Byzantine faulty clients. This paper presents novel protocols that provide atomic semantics despite Byzantine clients. Our protocols are the first to handle all problems caused by Byzantine clients. They prevent Byzantine c...
