Abstract
随着量子计算的发展,现有公钥签名体制面临严峻挑战,推动密码学界加速探索后量子签名方案。NIST 后量子密码标准化早期主要聚焦三类技术路线,即基于格的签名方案、基于哈希的签名方案,以及基于 MPC-in-the-Head / 零知识证明的签名方案。其中,零知识类签名仅依赖 AES、SHA 等对称原语,安全假设更为保守,但传统 MPCitH 方案普遍存在签名尺寸较大、运行效率较低的问题。为解决这一瓶颈,研究者提出了 VOLE-in-the-Head(VOLEitH)范式,将交互式 sVOLE 协议折叠为可公开验证的非交互式零知识证明,并结合 QuickSilver 风格的约束多项式零知识技术、O2C 承诺机制以及 Fiat–Shamir 变换构造高效的 NIZK 体系。在此基础上设计的 FAEST 签名方案以 AES 作为单向函数,仅依赖对称密码原语,在签名大小与运行速度两个方面均优于已有零知识类签名方案,展示了对称原语驱动后量子签名设计的良好前景。
