Universally Composable Simultaneous Broadcast against a Dishonest Majority and Applications. (arXiv:2305.06468v1 [cs.CR])

Simultaneous broadcast (SBC) protocols [Chor et al., FOCS 1985] constitute a
special class of broadcast channels which have proved extremely useful in the
design of various distributed computing constructions (e.g., multiparty
computation, coin flipping, e-voting, fair bidding). As with any communication
channel, it is crucial that SBC security is composable, i.e., it is preserved
under concurrent protocol executions. The work of [Hevia, SCN 2006] proposes a
formal treatment of SBC in the Universal Composability (UC) framework [Canetti,
FOCS 2001] and …
