Webfrom length-doubling pseudorandom generators (PRGs) [GGM86] and from pseudorandom synthesizers [NR95, NR04]. A pseudorandom synthesizer can be intuitively thought of as a length squaring PRG. Both constructions use a binary tree to determine the output of the function. In the case of [GGM86] we determine the value using a root to leaf path where as WebAlgebraic Pseudorandom Functions with Improved Efficiency from the Augmented Cascade* Omer Reingold, June 2024; Immunizing Encryption Schemes from Decryption Errors; Computational Hardness of Optimal Fair Computation: Beyond Minicrypt; Fall 2016 Dear Computer Science Alumni and Friends, These Are; Omer Reingold, June 2024

WebSynthesizers and their application to the parallel construction of pseudo-random functions Abstract: We present a new cryptographic primitive called pseudo-random synthesizer … 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. WebDec 31, 2024 · Pseudorandom numbers are essential to many computer applications, such as games and security. In games, random numbers provide unpredictable elements the player can respond to, such as … fan on a computer
