4.And this problem, called " integer factorization, " is exactly what each of your smartphones and laptops is using right now to keep your data secure.
5.We're looking for new, hard mathematical problems. We're looking for problems that, just like factorization, can be used on our smartphones and on our laptops today.
8.So really, factorization in the integers is not perfectly unique, it's almost unique, with the exception that some of the factors might be multiplied by -1. Analogy with primes Factoring works very similarly in Gaussian integers.
