Secure Multiparty Linear Programming Using Fixed-Point Arithmetic
Collaborative optimization problems can often be modeled as a linear program whose objective function and constraints combine data from several parties. However, important applicat...

Multiparty Computation from Somewhat Homomorphic Encryption
We propose a general multiparty computation protocol secure against an active adversary corrupting up to n−1 of the n players. The protocol may be used to compute securely arithm...

Near-Linear Unconditionally-Secure Multiparty Computation with a Dishonest Minority
Secure multiparty computation (MPC) allows a set of n players to compute any public function, given as an arithmetic circuit, on private inputs, so that privacy of the inputs as we...

Secure Arithmetic Computation with No Honest Majority
We study the complexity of securely evaluating arithmetic circuits over finite rings. This question is motivated by natural secure computation tasks. Focusing mainly on the case o...

Atomic Secure Multi-party Multiplication with Low Communication
We consider the standard secure multi-party multiplication protocol due to M. Rabin. This protocol is based on Shamir’s secret sharing scheme and it can be viewed as a practical ...
