The RSA encryption algorithm may be even more endangered now, courtesy of University of California, San Diego and Inria Nancy researchers.
Cyber Security News reported that a new signature forgery attack detailed in the researchers’ paper deployed a novel method to crack 1,024-bit RSA encryption without factoring (finding the two primes used to create a key). The researchers were able to break encryption with an academic CPU cluster that dedicated 1,380 CPU core-years to the problem over five months. Factoring a 1,024-bit RSA key, Cyber Security News noted, has previously been estimated to require 500,000 to 1 million CPU core-years.
RSA is…
