On the Concrete Security of Goldreich’s Pseudorandom Generator
Advances in Cryptology – ASIACRYPT 2018Pages 96–124https://doi.org/10.1007/978-3-030-03329-3_4AbstractLocal pseudorandom generators allow to expand a short random string into a long pseudo-random string, such that each output bit depends on a constant number d of input bits. Due to its extreme efficiency features, this intriguing primitive enjoys ...
