On the memory-tightness of hashed elgamal

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.
