Math Advance Suggest RSA Encryption Could Fall Within 5 Years

holy_calamity writes "The two encryption systems used to secure the most important connections and digital files could become useless within years, reports MIT Technology Review, due to progress towards solving the discrete logarithm problem. Both RSA and Diffie-Hellman encryption rely on there being no efficient algorithm for that problem, but French math professor Antoine Joux has published ...**on**August 7, 2013**Source:**Slashdot
