Black-Box Constructions of Composable Protocols without Set-Up
Abstract. We present the first black-box construction of a secure multiparty computation protocol that satisfies a meaningful notion of concurrent security in the plain model (wi...

Securing group key exchange against strong corruptions
When users run a group key exchange (GKE) protocol, they usually extract the key from some auxiliary (ephemeral) secret information generated during the execution. Strong corrupti...

Almost-Everywhere Secure Computation
Secure multi-party computation (MPC) is a central problem in cryptography. Unfortunately, it is well known that MPC is possible if and only if the underlying communication network...

Robustness for Free in Unconditional Multi-party Computation
We present a very efficient multi-party computation protocol unconditionally secure against an active adversary. The security is maximal, i.e., active corruption of up to t < n/...
