WebNew algorithm PKV. We recall the CRS of Kiltz-Wee QA-NIZK [106] Π0as includescrs = ([ ¯A,C]2, [P]1) where ¯A∈ Zkp×kdenotes the upper square matrix of A ∈ Z as into the … WebCompared with the ZK arguments (or QA-NIZK in the BPK model) in [ALSZ20], the QA-ZK arguments based on TSPHFs in [BBC+13,BP13] are less ef-ficient regarding proof size, computation and communication complexity. Moreover, it does not yield a modular construction for updatable QA-ZK, a gap that we close.

Web1 de jan. de 2024 · As mentioned, to construct our updatable asymmetric QA-NIZK arguments we start from the asymmetric QA-NIZK by González et al. (GHR) [] (cf. Fig. 1) and change GHR’s QA-NIZK by adding extra elements to the CRS so that the CRS becomes publicly verifiable and trapdoor extractable.Importantly, our aim for the … photo of umbilical hernia

dblp: On QA-NIZK in the BPK Model.

WebWe study Sub-ZK QA-NIZKs, where the CRS can depend on the language parameter. First, we observe that subversion zero-knowledge (Sub-ZK) in the CRS model corresponds … Web1 de mai. de 2000 · First, we make a conceptually important observation that Sub-ZK in the CRS model, as defined in [2,4,15], is equal to no-auxiliary-string non-black-box zero knowledge [21] in the BPK model [9, 38]. Web7 de set. de 2024 · Following , we will consider QA-NIZK in the BPK model and thus with a public-key updating (and not CRS-updating like in ) algorithm. Also, we allow updating of a previously created argument to one that corresponds to the new public key \(\textsc {pk}\), obtaining what we will call a key-and-argument-updatable QA-NIZK.
