Concurrently-secure blind signatures without random oracles or setup assumptions

By Carmit Hazay, Jonathan Katz, Chiu-yuen Koo and Yehuda Lindell


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 cryptographic assumptions and is the first to be proven secure in a concurrent setting (under any assumptions) without random oracles or a common reference string. Along the way, we also introduce new definitions of security for blind signature schemes
