Metric Pseudoentropy: Characterizations, Transformations and Applications, many cryptographic applications, like leakage-resilient cryptography, deterministic encryption or memory delegation. In this paper we develop a general method to characterize metric-type computational variants of entropy, in a way depending only on properties of a chosen class of test functions (ad

Nonuniform Indistinguishability and Unpredictability Hardcore Lemmas: New Proofs and Applications twhere the given problem is extremely hard. They find important applications in hardness amplification. In this paper we revisit the following two fundamental results:.Using only the standard min-max theorem and some basic facts about convex approximations in .. spaces, we provide alternative modular

Gambling, Computational Information and Encryption Security,ided an affirmative answer, using a compression-based notion of computational information to give a characterization equivalent to the standard computational notion of semantic security. We give two other equivalent characterizations. The first uses a computational formulation of Kelly’s (1957) mode

Query-Complexity Amplification for Random Oracles,ployed for example in password-based cryptographic schemes to impede brute-force attacks, and also in so-called proofs of work (used in protocols like Bitcoin) to show that a certain amount of computation was performed by a legitimate user. A natural approach to adjust the complexity of a hash funct

The Chaining Lemma and Its Application,rce distribution .. with high min-entropy and a number (say, . in total) of arbitrary functions (..,...,..) which are applied in succession to that source to generate the chain ........... ... . Intuitively, the Chaining Lemma guarantees that, if the chain is not too long, then either (i) the entire
