There's a New Way to Break RSA Encryption

"Signature forgery." It's a new way to break RSA keys — and it doesn't require factoring. Ars Technica reports on new research using classical computing to "reduce the current RSA security level to an…

  • Researchers from UC San Diego propose new RSA encryption-breaking method
  • Attack doesn't require factoring, reduces security to 265, 290, 2119 bits
  • Blind-signature RSA implementation attack practical, warrants post-quantum transition
