Researchers forge 1024-bit RSA signatures at near-record speed
Original: Forging 1024-bit RSA signatures in nearly SNFS time [pdf]
A new cryptography paper describes forging 1024-bit RSA signatures in time close to the special number field sieve, a faster attack method previously thought impractical at this key size. The result, published on the IACR eprint archive, suggests 1024-bit RSA keys offer less security margin than assumed, and readers are debating whether older systems still relying on them need urgent upgrades to 2048-bit or larger keys.
Why now: A new paper showing practical progress against 1024-bit RSA undermines a key size still used in legacy systems.
