Notions of black-box reductions revisited
WebApr 16, 2024 · In the classical world, commitments are equivalent to the existence of one-way functions. It is also known that the most desired form of commitments in terms of their round complexity, i.e., non-interactive commitments, cannot be built from one-way functions in a black-box way [Mahmoody-Pass, Crypto’12]. However, if one allows the parties to ... WebJan 13, 2024 · For some cryptographic primitives, such as one-way permutations and homomorphic encryption, we know that the answer is yes ---they imply hard problems in N P ∩ c o N P and S Z K, respectively. In contrast, one-way functions do not imply such hard problems, at least not by black-box reductions.

WebDeflnition 1 (Class-speciflc black-box reductions). Let P;P0 be two com- putational problems, and C a class of functions. We say that R is a C-black-box reduction from P to P0, if R is a probabilistic polynomial-time oracle machine such that for every oracle A 2 C that solves P0, RA solves P. If R queries A non-adaptively, we say that the reduction is non … WebFor this purpose, Impagliazzo and Rudich [IR89] introduced the notion of black-box reductions.
