WebJul 4, 2024 · Abstract The current state of the art in watermarked public-key encryption schemes under standard cryptographic assumptions suggests that extracting the embedded message requires either linear time in the number of marked keys or the a-priori knowledge of the marked key employed in the decoder. 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.
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 … WebNov 10, 2024 · Modern cryptography takes a completely different approach. 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, …
