A Counterexample to the Chain Rule for Conditional HILL Entropy
Computational Entropy HILL Entropy Chain Rule
2016/1/7
Most entropy notions H(.) like Shannon or min-entropy satisfy a chain rule
stating that for random variables X, Z and A we have H(X|Z, A) ≥ H(X|Z) −
|A|. That is, by conditioning on A the entr...
Computational notions of entropy (a.k.a. pseudoentropy) have
found many applications, including leakage-resilient cryptography, deterministic
encryption or memory delegation. The most important tool...
