Web3 Unravelled Linearization and the Boneh-Durfee Attack In this section, we will apply the method of unravelled linearization, introduced by Herrmann and May [HM09], to attack RSA with small secret exponent d. This will lead to an elementary proof of the Boneh-Durfee bound d ≤ N0.292. WebI use this implementation of Boneh and Durfee, which is pretty much Wiener's method but with Lattices and it works on higher values of \( d \). That means that if the private key was bigger, these folks would not have …
