    Non-interactive Zero-Knowledge Functional Proofs

    In this paper, we consider to generalize NIZK by empowering a prover to share a witness in a fine-grained manner with verifiers. Roughly, the prover is able to authorize a verifier to obtain extra information ...

    Leakage-Resilient Inner-Product Functional Encryption in the Bounded-Retrieval Model

    We propose a leakage-resilient inner-product functional encryption scheme (IPFE) in the bounded-retrieval model (BRM). This is the first leakage-resilient functional encryption scheme in the BRM. In our leakag...

    Adaptive-Secure Identity-Based Inner-Product Functional Encryption and Its Leakage-Resilience

    There are lots of applications of inner-product functional encryption (IPFE). In this paper, we consider two important extensions of it. One is to enhance IPFE with access control such that only users with a p...

    From Quadratic Functions to Polynomials: Generic Functional Encryption from Standard Assumptions

    The “all-or-nothing” notion of traditional public-key encryptions is found to be insufficient for many emerging applications in which users are only allowed to obtain a functional value of the ciphertext witho...

    A New Privacy-Preserving Searching Model on Blockchain

    It will be convenient for users if there is a market place that sells similar products provided by different suppliers. In physical world, this may not be easy, in particular, if the suppliers are from differe...

    An ORAM Scheme with Improved Worst-Case Computational Overhead

    We construct a statistically secure ORAM with computational overhead of \(O(\log ^2N\log \log N)\) . Moreover, when accessing co...
