Researchers forge 1024-bit RSA signatures at near-SNFS 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, the fastest known factoring method. If the techniques hold up, they suggest 1024-bit RSA keys, widely considered obsolete but still found in legacy systems, are weaker against well-resourced attackers than standard estimates assumed.
Why now: The attack speeds up factoring of legacy 1024-bit RSA keys, which matters for the security of old certificates and protocols.
