In this talk, we continue the foundational work on backdoored pseudorandom generators (PRGs) initiated by Dodis et al., providing both positive and negative results. We first revisit the backdoored PRG setting of Dodis et al., showing that PRGs can be more strongly backdoored than was previously envisaged. We then turn our attention to a much stronger type of generator, robust pseudorandom number generators (PRNGs) with input, and show that even these can be backdoored. Finally, we provide a (positive) impossibility result: a bound limiting the extend to which PRNGs can be backdoored. |
