GIFT stands for Graphical Integer Factorization Technique. It is an original method to factor composite numbers using graph theory. Presently, we are looking for a partner (individual, company, institution or government) that has the required computational resources to test if the given technique can factor RSA-1024 bits in a reasonable amount of t...

A method and a system to encode and decode digital data into three-dimensional representations.
Conference Paper
While most of the presently known factorization methods employ advanced mathematical tools in all phases of their respective processes the proposed algorithm is very simple and direct. The technique only applies to semiprimes or the product of two different but equal-sized primes and is based on reversing the decimal digits of the modulus. Since ba...
Conference Paper
A new algorithm which correctly identifies every positive integer tested as being either prime or composite is considered. In fact, the first one hundred Carmichael numbers were tested and each one resulted composite as expected. It is well known that other primality tests exist that can also identify Carmichael numbers as composites, but the given...

The aim is to find an efficient algorithm that is able to factor the RSA-1024 bit modulus only using classical computers. Such algorithm must be both polynomial in time and deterministic in nature.
