WebThese schemes are based on techniques from cryptography with certified deletion. - We also initiate a study of classical cryptographic schemes with (bounded) post-quantum leakage-resilience. These schemes resist side-channel attacks performed by adversaries with quantum capabilities which may even share arbitrary entangled quantum states. WebDec 8, 2024 · In this paper we show several quantum chosen-plaintext attacks (qCPAs) on contracting Feistel structures. In the classical setting, a d-branch r-round contracting Feistel structure can be shown to be PRP-secure when d is even and $r \ge 2d-1$, meaning it is secure against polynomial-time chosen-plaintext attacks.We propose a polynomial-time … personal rights foster youth
