New Guess-and-Determine Attack on the Self-Shrinking Generator
We propose a new type of guess-and-determine attack on the self-shrinking generator (SSG). The inherent flexibility of the new attack enables us to deal with different attack condi...

On the Provable Security of an Efficient RSA-Based Pseudorandom Generator
Pseudorandom Generators (PRGs) based on the RSA inversion (one-wayness) problem have been extensively studied in the literature over the last 25 years. These generators have the a...
