Low Secret Exponent RSA Revisited SpringerLink

WebAbstract. In 1998, Boneh, Durfee and Frankel [4] presented several attacks on RSA when an adversary knows a fraction of the secret key bits. The motivation for these so-called partial key exposure attacks mainly arises from the study of side-channel attacks on RSA. With side channel attacks an adversary gets either most significant or least ... WebThe attack uses ideas due to Coppersmith for finding solutions to polynomial equations using lattices.

WebFeb 1, 2024 · When e ≈ N, the Boneh–Durfee attack outperforms ours. As a result, we could simultaneously run both attacks, our new attack and the classical Boneh–Durfee attack as a backup. The rest of the paper is organized as follows. In Section 2, we review some preliminary results on continued fractions. WebDan Boneh and Glenn Durfee Abstract— We show that if the private exponent used in the RSA (Rivest–Shamir–Adleman) public-key cryptosystem is less than 0 292 then the system is insecure. This is the first improve-ment over an old result of Wiener showing that when is less than 0 25 the RSA system is insecure. We hope our approach can be
