A paper appeared in early March with a tantalizing conclusion in the abstract: This destroys the RSA cryptosystem If the claim proves correct, a good part of the data thats encrypted at rest or in motion might not be safe. Some cryptographers are looking for a stronger foundation built out of multiple algorithms implemented with protocols that make switching simpler. The world must be more agile, they argue, because there are many potential cracks that could appear. Theyre looking for RSA replacements because the algorithm is just one encryption algorithm.”]
