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]. Web4 de nov. de 2024 · Compared with the ZK arguments (or QA-NIZK in the BPK model) in , the QA-ZK arguments based on TSPHFs in [12, 14] are less efficient regarding proof size, computation and communication complexity. Moreover, it does not yield a modular construction for updatable QA-ZK, a gap that we close.
