WebUsing a simple RO simulation technique, we provide memory-tight reductions of security of the Cramer-Shoup and the ECIES version of Hashed-ElGamal KEM.We prove memory-tight reductions for different variants of Fujisaki-Okamoto Transformation. We analyze the modular transformations introduced by Hofheinz, Hövermanns and Kiltz (TCC 2024). WebThe problem seems to be inherent as all the other existing results on memory-tightness are lower bounds and impossibility results. In fact, Auerbach et al.conjectured that a memory-tight reduction for [inline-graphic not available: see fulltext]security of Hashed-ElGamal KEM is impossible. We refute the above conjecture.

Web25 de jan. de 2024 · Our constructions are obtained by applying the KEM-DEM paradigm to variants of Hashed ElGamal and the Fujisaki-Okamoto transformation that are augmented by adding uniformly random strings to their ciphertexts. The reductions carefully combine recent proof techniques introduced by Bhattacharyya’20 and Ghoshal-Ghosal-Jaeger … Web25 de mai. de 2024 · In fact, Auerbach et al. conjectured that a memory-tight reduction for Open image in new window security of Hashed-ElGamal KEM is impossible.
