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/...

New Monotones and Lower Bounds in Unconditional Two-Party Computation
Since bit and string oblivious transfer and commitment, two primitives of paramount importance in secure two- and multi-party computation, cannot be realized in an unconditionally ...

On the Hardness of Information-Theoretic Multiparty Computation
We revisit the following open problem in information-theoretic cryptography: Does the communication complexity of unconditionally secure computation depend on the computational com...

MPC vs. SFE : Unconditional and Computational Security
Abstract. In secure computation among a set P of players one considers an adversary who can corrupt certain players. The three usually considered types of corruption are active, pa...
