关于在通用向量空间中隐藏油子空间的 Schnorr 类知识证明

摘要

一UOV公钥隐一特异线性子空:乃中央油坐标子空之公共坐标像。于中央坐标中,每UOV多项式之齐次二次部不含油油单项式。故每诚然生成之UOV公钥,其公共齐次二次式当限制于此隐油子空时即消。吾等形式化此隐油子空关系,构一肖Schnorr之Sigma协议,以证知此子空而不泄之。证物含矩阵$B,W$,适足$WB=I_o$及$Q_k(Bz)\equiv 0$于一切公共二次式$Q_k$。证者线性掩蔽证物,应挑战$c$以$Z=A+cB$、$Y=E+cW$,得一具计算3特异完备性及计算诚然验证零知识之协议。吾等证一通用唯一性定理:于随机齐次UOV模型中,隐油子空,以压倒性概率,唯一为$o$维公共零子空。此唯一性界于UOV型参数中明确且可忽。是强化协议之诠释,非仅证知油类子空,实证知唯一隐油子空。吾等提供小参数之经验观察,并论应用与局限。
