The Power of Proofs-of-Possession: Securing Multiparty Signatures against Rogue-Key Attacks
Abstract. Multiparty signature protocols need protection against roguekey attacks, made possible whenever an adversary can choose its public key(s) arbitrarily. For many schemes, p...

Cryptographic Protocol Synthesis and Verification for Multiparty Sessions
We present the design and implementation of a compiler that, given high-level multiparty session descriptions, generates custom cryptographic protocols. Our sessions specify pre-a...

Secure Multi-party Computation Minimizing Online Rounds
Multi-party secure computations are general important procedures to compute any function while keeping the security of private inputs. In this work we ask whether preprocessing can...

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...

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...
