All previous constructions of general multiparty computation protocols that are secure against adaptive corruptions in the concurrent setting either require some form of setup or non-standard assumptions. In this paper we provide the first general construction of secure multi-party computation protocol without any setup that guarantees composable security in the presence of an adaptive adversary based on standard polynomial-time assumptions. We prove security under the notion of "UC withdoi:10.1007/978-3-662-53641-4_16 fatcat:7mqiz66zhbax5iugapjuzgdoeq
