The basic assumption is: It doesn’t matter if a cryptogram reveals information about the message. What matters is whether can efficiently extract this information. If we assume that has an unlimited computational capacity, then the previous proposition does not hold. Hence, …

WebJan 10, 2016 · We believe that the lack of standards of what is accepted as a reasonable cryptographic assumption can be harmful to the credibility of our field. Therefore, there is a great need for measures according to which we classify and compare assumptions, as to which are safe and which are not. WebLattice-Based Cryptography. Lattice-based cryptography is one of the leading candidates for post-quantum cryptography. A major focus of my work has been on constructing new cryptographic primitives such as zero-knowledge proof systems, watermarking, and more, from standard lattice assumptions. great isaac shipwreck

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. WebApr 16, 2024 · Indistinguishability Obfuscation \((i\mathcal {O})\) is a highly versatile primitive implying a myriad advanced cryptographic applications. Up until recently, the state of feasibility of \(i\mathcal {O}\) was unclear, which changed with works (Jain-Lin-Sahai STOC 2024, Jain-Lin-Sahai Eurocrypt 2024) showing that \(i\mathcal {O}\) can be finally … 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 … floating money transaction
