RSA Factoring Attack Evolves Into Faster Forgery Method

Researchers have discovered a way to forge digital signatures on 1024-bit RSA keys, using a massive 1380 CPU core-years of computing power over five months - but here's the catch: it doesn't actually break the keypair. This clever forgery method only works with so-called "pure signatures" created with RSA and no extra formatting.
