On the security of osidh
Web1 de jan. de 2024 · We give a proof of a fundamental theorem for OSIDH. The theorem was stated by Colò and Kohel without proof. Furthermore, we consider parameters of OSIDH, give a sufficient condition on the parameters for the protocol to work, and estimate the size of the parameters for a certain security level. WebIn this article we develop the cryptographic mechanism that should be used to achieve confidential and authentic data storage in the encrypt-to-self setting, i.e., where …

Web5 de dez. de 2024 · As pointed out in [], the original SIDH key agreement protocol is not secure when using the same secret key over multiple instances of the protocol.This can be fixed by a Fujisaki–Okamoto transform [] at the cost of a drastic loss of performance, requiring additional points in the protocol.These issues motivated the description of … WebThis work revisits the security of OSIDH by presenting a new attack, building upon previous work of Onuki, which has exponential complexity, but it practically breaks Colò and Kohel’s parameters unlike Onuki's attack. The Oriented Supersingular Isogeny Diffie–Hellman is a postquantum key exchange scheme recently introduced by Colò and Kohel. It is based …
