WebA Modular Analysis of the Fujisaki-Okamoto Transformation (Hofheinz, Hövelmanns & Kiltz, TCC 2024) Additional improvements and variants: An efficient CCA-secure cryptosystem over ideal lattices from identity-based encryption (Yang, Wu, Zhang & Chen - Comp. Math. Appl, 2012) WebC. Fujisaki-Okamoto Transformation Fujisaki-Okamoto transformation [3,4,5] is a general methodology to convert an IND-CPA secure encryption scheme into an IND-CCA secure KEM. In the Fujisaki-Okamoto transformation, the encapsulation procedure is a de-terministic version of the encryption, where all randomness is

WebN2 - We investigate all NIST PQC Round 3 KEM candidates from the viewpoint of fault-injection attacks: Classic McEliece, Kyber, NTRU, Saber, BIKE, FrodoKEM, HQC, NTRU Prime, and SIKE. All KEM schemes use variants of the Fujisaki-Okamoto transformation, so the equality test with re-encryption in decapsulation is critical. WebA Modular Analysis of the Fujisaki-Okamoto Transformation. D. Hofheinz, Kathrin Hövelmanns, Eike Kiltz; Computer Science, Mathematics. TCC. 2024; TLDR. The Fujisaki-Okamoto (FO) transformation turns any weakly secure public-key encryption scheme into a strongly secure one in the random oracle model. minifig cat toys

Web9 giu 2015 · Recently, Fujisaki and Okamoto provided a revised version of the Fujisaki-Okamoto transformation [1], a generic transformation for achieving IND-CCA2 … WebAbstract. Newer variants of the Fujisaki–Okamoto transformation are used in most candidates of the third round of the NIST Post-Quantum Cryptography standardization call in the category of public key encryption schemes. These transformations are applied to obtain a highly secure key encapsulation mechanism from a less secure public key ... Web16 dic 1999 · Abstract. This paper shows a generic and simple conversion from weak asymmetric and symmetric encryption schemes into an asymmetric encryption scheme which is secure in a very strong sense — indistinguishability against adaptive chosen-ciphertext attacks in the random oracle model. In particular, this conversion can be … most played on spotify by me
