Abstract. We show a new protocol for blind signatures in which security is preserved even under arbitrarily-many concurrent executions. The protocol can be based on standard crypto...

In this paper, we present two failures in the blind signatures based voting system Votopia [2] which has been tested during the last World Soccer Cup. We then propose a fix which r...
