【Abstract】 Distributed multiplication computation protocols are widely used as basic cryptographic protocols. They are basic modules to construct threshold cryptosystems, and also important components of secure multiparty computation. Several important distributed multiplication schemes are analyzed in this paper, and based on verifiable secret sharing, some robust distributed multiple multiplication protocols are presented, one of which, the parallelizable non interactive protocol, is more efficient, and has the property of non interaction.更多还原
