Papers

  • Updatable Signatures and Message Authentication Codes: https://eprint.iacr.org/2021/365.pdf

  • Multiparty Computation with Covert Security and Public Verifiability: https://eprint.iacr.org/2021/366.pdf

  • Memory Optimization Techniques for Computing Discrete Logarithms in Compressed SIKE: https://eprint.iacr.org/2021/368.pdf

  • Nova: Recursive Zero-Knowledge Arguments from Folding Schemes

    • folding schemes for NP/devise a folding scheme for relaxed R1CS/construct incrementally verifiable computation (IVC) from folding schemes by using a “verifier circuit” that at each recursive step folds an entire R1CS instance representing computation (including a copy of the verifier circuit) at its prior step into a running relaxed R1CS instance/ Nova, a new zero-knowledge proof system for incremental computations/ Nova does not require a trusted setup nor performs FFTs
    • https://eprint.iacr.org/2021/370.pdf

  • Explicit connections between supersingular isogeny graphs and Bruhat–Tits trees: https://eprint.iacr.org/2021/372.pdf

  • T5: Hashing Five Inputs with Three Compression Calls

    • Given 2n-to-n compression functions h1, h2, h3, we build a new 5n-to-n compression function T5, using only 3 compression calls
    • https://eprint.iacr.org/2021/373.pdf

  • ZXAD: Zero-knowledge Exit Abuse Detection for Tor: https://eprint.iacr.org/2021/374.pdf

  • On the Impossibility of Post-Quantum Black-Box Zero-Knowledge in Constant Rounds

    • constant-round post-quantum zeroknowledge protocols for NP exist if and only if we use non-black-box techniques or relax certain security requirements
    • https://eprint.iacr.org/2021/376.pdf

  • Attacks and weaknesses of BLS aggregate signatures: https://eprint.iacr.org/2021/377.pdf

  • Multiparty Reusable Non-Interactive Secure Computation from LWE: https://eprint.iacr.org/2021/378.pdf

  • Towards Practical and Round-Optimal Lattice-Based Threshold and Blind Signatures: https://eprint.iacr.org/2021/381.pdf

  • Signatures with Tight Multi-User Security from Search Assumptions: https://eprint.iacr.org/2021/382.pdf
