摘要
提出了可公开求值伪随机函数的概念，它是标准伪随机函数的非平凡扩展。短暂,PEPRFs定义包含一个NP语言L /域X证人很难提取平均每个密钥sk与公钥pk。对于任何X∈L,除了评估F sk (X)使用sk作为标准脉冲重复频率,也能够评估一个F sk (X)与pk, X和证人w X∈PEPRFs L .我们进行正式研究,专注于应用,结构,和扩展。更详细地说:
Publicly evaluable pseudorandom functions and their applications
We put forth the notion of publicly evaluable pseudorandom functions (PEPRFs), which is a non-trivial extension of the standard pseudorandom functions (PRFs). Briefly, PEPRFs are defined over domain X containing an NP language L in which the witness is hard to extract on average, and each secret key sk is associated with a public key pk. For any x ∈ L, in addition to evaluate F sk (x) using sk as in the standard PRFs, one is also able to evaluate F sk (x) with pk, x and a witness w for x ∈ L. We conduct a formal study of PEPRFs, focusing on applications, constructions, and extensions. In more details:
