WebOne important distinction of the new notion from SPHFs is that in a smooth NIZK the public evaluation of the hash on a language member using the projection key does not require … WebNIZK arguments of [JR14, KW15] can be easily extended to be smooth. As a rst application, we show that in the Gennaro-Lindell paradigm of designing 4 Since their construction uses the commit and prove paradigm of GS-NIZK proofs, their (composite-) construction is a smooth NIZK with a small tweak: they obtain
Web18 Nov 2024 · We initiate the study of non-interactive zero-knowledge (NIZK) arguments for languages in QMA. Our first main result is the following: if Learning With Errors (LWE) is hard for quantum computers, then any language in QMA has an NIZK argument with preprocessing. The preprocessing in our argument system consists of (i) the generation … Webof [BGN05]. We can construct NIZK arguments with adaptive soundness by limiting the adversary to picking circuits of size ‘(k) such that ‘(k)‘(k)ν SD(k) is negligible4 Second, we …

WebOur Contribution. We provide space-e cient NIZK arguments showing that an element is a composite residue in the group Z N2, for an RSA modulus N= pq. In particular, we can argue that Paillier [64] or Damg ard-Jurik [34] ciphertexts decrypt to 0. These arguments extend to handle multiplicative relations between Paillier ciphertexts.
