Researchers forge 1024-bit RSA signatures without factoring the key
A team from UC San Diego and Inria has done something cryptographers long assumed was impossible or at least pointless: forged 1024-bit RSA signatures without ever factoring the modulus. The paper, posted September 20 by Laura Shea, Miro Haller, Adam Suhl, Nadia Heninger, and Emmanuel Thomé, ran a 2007 algorithm at real scale and found […]
The signing keys in US driver’s license barcodes were hiding in plain sight
Flip over a US driver’s license and you will find a PDF417 barcode that encodes your name, birth date, license number, and a pile of jurisdiction-specific fields. Most states leave it as plaintext. A few sign it. Security researcher Ryan Fahey has now shown that for the states whose cards are made by Canadian Bank […]
