WebSep 30, 2024 · Isogeny-based assumptions often have unique efficiency and security properties, which makes building new cryptographic applications from them a potentially tedious and time-consuming task. In this work, we propose a new framework based on group actions that enables the easy usage of a variety of isogeny-based assumptions. rod wave pray 4 love zipWebJul 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. tesi mia

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, … WebIn this project, we study and construct new proof systems that satisfy special properties such as zero-knowledge (where we require that the proof does not reveal anything more about the statement other than its truth) and succinctness (where proofs are short and can be verified quickly).
