Efficient Pseudorandom Generators from Exponentially Hard One-Way Functions

  title={Efficient Pseudorandom Generators from Exponentially Hard One-Way Functions},
  author={Iftach Haitner and Danny Harnik and Omer Reingold},
In their seminal paper [HILL99], H̊astad, Impagliazzo, Levin and Luby show that a pseudorandom generator can be constructed from any one-way function. This plausibility result is one of the most fundamental theorems in cryptography and helps shape our understanding of hardness and randomness in the field. Unfortunately, the reduction of [HILL99] is not nearly as efficient nor as security preserving as one may desire. The main reason for the security deterioration is the blowup to the size of… CONTINUE READING
