We consider natural ways to extend the notion of Zero-Knowledge (ZK) Proofs beyond decision problems. Specifically, we consider search problems, and define zero-knowledge proofs in this context as int...
We present an additively homomorphic commitment scheme with hardness based on the Ring-SIS problem. Our construction is statistically hiding as well as computationally binding and allows to commit ...
We propose a general technique that allows improving the complexity of zero-knowledge protocols for a large class of problems where previously the best known solution was a simple cut-andchoose styl...
Many cryptographic primitives---such as pseudorandom generators, encryption schemes, and zero-knowledge proofs---center around the notion of \emph{approximability}. For instance, a pseudorandom genera...
We present a protocol that allows to prove in zero-knowledge that committed values $x_i, y_i, z_i$, $i=1,\dots,l$ satisfy $x_iy_i=z_i$, where the values are taken from a finite field $K$, or are integ...

Zero-knowledge proofs of knowledge (ZK-PoK) for discrete logarithms and related problems are indispensable for practical cryptographic protocols. At \emph{Eurocrypt 2009}, Camenisch, Kiayias, and Yung...

Efficient zero-knowledge proofs of knowledge (ZK-PoK) are basic building blocks of many practical cryptographic applications such as identification schemes, group signatures, and secure multiparty c...
Hada and Tanaka [11, 12] showed the existence of 3-round, negligible-error zero-knowledge arguments for NP based on a pair of non-standard assumptions, here called KEA1 and KEA2. In this paper we sh...
