Threshold Decryption and Zero-Knowledge Proofs for Lattice-Based Cryptosystems
We present a variant of Regev’s cryptosystem first presented in [Reg05], but with a new choice of parameters. By a recent classical reduction by Peikert we prove the scheme sema...

A Note on Universal Composable Zero Knowledge in Common Reference String Model
Pass observed that universal composable zero-knowledge (UCZK) protocols in the common reference string (CRS) model, where a common reference string is selected trustily by a truste...

Zero-Knowledge Sets
We show how a polynomial-time prover can commit to an arbitrary finite set Ë of strings so that, later on, he can, for any string Ü, reveal with a proof whether Ü ¾ Ë or Ü ...

Proving in Zero-Knowledge that a Number Is the Product of Two Safe Primes
Abstract. We present the first efficient statistical zero-knowledge protocols to prove statements such as: – A committed number is a prime. – A committed (or revealed) number ...

Adaptive Zero-Knowledge Proofs and Adaptively Secure Oblivious Transfer
In the setting of secure computation, a set of parties wish to securely compute some function of their inputs, in the presence of an adversary. The adversary in question may be st...
