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...
Efficient Commitments and Zero-Knowledge Protocols from Ring-SIS with Applications to Lattice-based Threshold Cryptosystems
Efficient Commitments Zero-Knowledge Protocols
2016/12/8
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

2012/3/26
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...

2011/7/25
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...

2009/3/20
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...
