Resumen de Number-cracking factory gets to work
The first tests of a "factorization factory" have beaten the record for breaking gigantic numbers down into their prime-number building blocks. It might one day force firms to strengthen their online encryption. All non-prime numbers can be made by multiplying prime numbers together. Cryptographic algorithms use the fact that reversing-engineering this multiplication, or factorizing, is very difficult for large numbers. New factorizing methods are tested on huge "RSA numbers", each of which is the product of multiplying two prime numbers, known only to encryption firm RSA Security.
