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 ...

Modulo Reduction for Paillier Encryptions and Application to Secure Statistical Analysis
Abstract. For the homomorphic Paillier cryptosystem we construct a protocol for secure modulo reduction, that on input of an encryption x with x of bit length x and a public ‘mod...

Zero-knowledge from secure multiparty computation
A zero-knowledge proof allows a prover to convince a verifier of an assertion without revealing any further information beyond the fact that the assertion is true. Secure multipar...

Secure Computation with Fixed-Point Numbers
Abstract. Secure computation is a promising approach to business problems in which several parties want to run a joint application and cannot reveal their inputs. Secure computatio...

Ordered multisignatures and identity-based sequential aggregate signatures, with applications to secure routing
We construct two new multiparty digital signature schemes that allow multiple signers to sequentially produce a compact, fixed-length signature. First, we introduce a new primiti...
