ePrint Report: One-way Functions and Hardness of (Probabilistic) Time-Bounded Kolmogorov Complexity w.r.t. Samplable Distributions
Yanyi Liu, Rafael Pass
Consider the recently introduced notion of \emph{probabilistic
time-bounded Kolmogorov Complexity}, pK^t (Goldberg et al,
CCC'22), and let MpK^tP denote the language of pairs (x,k) such that pK^t(x) \leq k.
We show the equivalence of the following:
- MpK^{poly}P is (mildly) hard-on-average w.r.t. \emph{any} samplable
distribution D;
- MpK^{poly}P is (mildly) hard-on-average w.r.t. the
\emph{uniform} distribution;
- Existence of one-way functions.
As far …
