WebOct 7, 2024 · The problem here is that you have a divisor p of n of the form. p h ⋅ 10 208 + p m ⋅ 10 108 + p l, where you know p h and p l, but not p m < 10 100 ⪅ n 0.16. Clearly, the polynomial f ( x) = x ⋅ 10 108 + p h ⋅ 10 208 + p l will be 0 modulo p for the right x = p m, which is known to be small. So we can apply here the GCD generalization ...

Web1.1 Common factor attack on RSA In 2012, Heninger et al. [4] and Lenstra et al. [5] introduced the idea of this attack. They performed an Internet wide survey, mined all TLS and SSH certi cates, and performed an exhaustive pairwise-GCD computation including every RSA modulus thus obtained. It is intuitively expected that two 1024-bit RSA moduli ... WebAs explained by Alexander May in pages 40 and 41 of his thesis what you ask is always doable if the unknown bits are consecutive (and you have at least known bits).
