A team of researchers in Japan have successfully broken a 278-digit piece of crypto in less than 200 days.
Researchers from Fujitsu, Japan?s National Institute of Information and Communications Technology (NICT), and Kyushu University attempted to break a 278-digit (923-bit) pairing-based cryptography. Previously this was thought to require several hundred thousand years, but with current computer processing the team successfully broke the encryption in 148 days. According to Fujitsu, pairing-based cryptography is the next-generation standard for government systems and international bodies.
Fujitsu said it combined several new techniques, including parallel programming methods. The team used 21 personal computers with a total of 252 cores to crack the encryption.
According to TechWeek Europe, ?We were able to overcome this problem by making good use of various new technologies, that is, a technique optimising parameter setting that uses computer algebra, a two dimensional search algorithm extended from the linear search, and by using our efficient programing techniques to calculate a solution of an equation from a huge number of data, as well as the parallel programming technology that maximises computer power.?
