This is an easy-to-understand algorithm of integer factorization with heuristically evaluated complexity L(4/15, 2), which is better than the general number field sieve algorithm with L(1/3, 1.923).
NFB searches common factors of the quadratic residues modulo n using GCD. All relations are processed by the Gaussian elimination procedure. Different strategies of searching the relations can be applied, many giving complexity better than L(1/3, 1.923).

Passwordless Authentication and Passwordless Security

Identity is everything. Protect it with Duo.

It’s no secret — passwords can be a real headache, both for the people who use them and the people who manage them. Over time, we’ve created hundreds of passwords, it’s easy to lose track of them and they’re easily compromised. Fortunately, passwordless authentication is becoming a feasible reality for many businesses. Duo can help you get there.

User Reviews

  • You do not need to be a specialist in number theory to comprehend this algorithm and try different strategies of searching quadratic residues mod N . Good for home research in number theory :) or as a material for a diploma thesis. Significant work is needed to parallelize this on GPU or CPU for factorization of really large numbers.
