Private Simultaneous Messages (PSM) is a minimal model for information-theoretic non-interactive multi-party computation. In the 2-party case, Beimel et al. showed every function f:[N]×[N]→{0,1}f:[N]×...

We study the efficiency of computing arbitrary k-argument functions in the Private Simultaneous Messages (PSM) model of (Feige et al. STOC'94, Ishai and Kushilevitz ISTCS'97). This question was recent...

We study the notion of {\em ad hoc secure computation}, recently introduced by Beimel et al. (ITCS 2016), in the context of the {\em Private Simultaneous Messages} (PSM) model of Feige et al.\ (STOC 2...
