Achieving password-hashing scheme over lattices

Abstract: Pointceva方 案(IACR ePrint2013/833)、 Kiefer-Manulis方 案(ESORICS'14)、 Pointcheval-Wang方案(ASIACCS'17)与平滑投影散列函数(smooth projective hash function, SPHF)集 成, 但这些方案无法实现后量子安全且仍依赖于ROM模型. 因此, 本文着重研究如何在标准模型下设 计后量子安全的口令散列方案, 并给出可证明安全性分析. 尽管所提方案尚不能应用于实际, 但为构造 实际的后量子安全的口令认证及密钥交换协议奠定了基础.
