WebAug 12, 2024 · The idealized assumptions typically make information-theoretic proof systems useless as standalone objects. On the other hand, they allow us to construct them unconditionally, without relying on cryptographic assumptions. We will discuss several kinds of information-theoretic proof systems with incomparable features. WebTraditionally, there were a few well-studied computational assumptions under which cryptographic schemes were proven secure. These assumptions can be partitioned into …
Webany NP statement under general (rather than number theoretic) assumptions, and how to enable polynomially many provers to give polynomially many such proofs based on a single random string. Our constructions can be used in cryptographic applications in which the prover is restricted to polynomial time. Key words. WebMay 10, 2024 · And the provable emphasizes the mathematical assumptions or cryptography primitives. But it also related to the computational power. Provable security refers to any security that can be formally proved, even if there are no mathematical hardness assumptions (e.g., information-theoretic security does not necessarily involve …

WebDec 1, 2024 · We show that “mainstream” cryptographic assumptions such as DDH and LWE naturally imply (bounded) HOWFs/IHwUFs/IHwPRFs. We also show that a (bounded) group-homomorphic PKE implies a (bounded) IHwPRF. This allows instantiating these primitives from any concrete assumption that implies a (bounded) homomorphic PKE (e.g., QR and …
