WebAug 19, 2001 · First, assuming that the conjugacy problem is a one-way function, say f, we show which particular bit of the argument xis pseudorandom given f(x). Next, under the decision Ko-Lee assumption, we construct two provably secure pseudorandom schemes: a pseudorandom generator and a pseudorandom synthesizer. References WebNamely, we show that the standard constructions of pseudorandom functions from pseudorandom generators or pseudorandom synthesizers are secure, even when the adversary can make quantum queries. We also show that a direct construction from lattices is quantum-secure.

WebSynthesizers and LWRE. The main intermediate object that we use to con-struct our PRF is a pseudorandom synthesizer (De nition4.5), which was rst introduced by Naor and Reingold [45]. They showed that a pseudorandom syn-thesizer that can be computed by a low-depth circuit can be used to construct a PRF that can also be computed by a low-depth ... WebSince pseudo-random synthesizers [NR95, Rei98] are equivalent to one-way functions, we also achieve an equivalence between DCP secure functions and synthesizers. In the full … WebDec 5, 2024 · Pseudorandom synthesizers, which we define in Sect. 3, are efficient ways to construct parallelizable PRFs. In our work, we construct a keyed synthesizer $S_{\ell }$which has a square matrix $\mathbf {S}\in \mathbb {Z}_{q}^{m \times m}$with entries sampled uniformly at random over $\mathbb {Z}_{q}$as a key. movie where mom and daughter go on vacation
