Security Against Covert Adversaries: Efficient Protocols for Realistic Adversaries
Abstract. In the setting of secure multiparty computation, a set of mutually distrustful parties wish to securely compute some joint function of their private inputs. The computati...

Scalable Secure Multiparty Computation
We present the first general protocol for secure multiparty computation which is scalable, in the sense that the amortized work per player does not grow, and in some natural settin...

How Many Oblivious Transfers Are Needed for Secure Multiparty Computation?
Oblivious transfer (OT) is an essential building block for secure multiparty computation when there is no honest majority. In this setting, current protocols for n 3 parties requ...

Constant-Round Multiparty Computation Using a Black-Box Pseudorandom Generator
We present a constant-round protocol for general secure multiparty computation which makes a black-box use of a pseudorandom generator. In particular, the protocol does not requir...
