This is known in computer science as "software obfuscation," and it is the first time it has been accomplished.

TechnologyMon, 29 Jul 2013 18:54:46 EDTnews294342870Researchers test quantum encryption hacking risk(Phys.org) —Quantum communication systems offer the promise of virtually unbreakable encryption. Unlike classical encryption, which is used to send secure data over networks today and whose security depends on the difficulty of solving mathematical problems like the factoring of large numbers, most quantum encryption schemes keep the encryption key separate from the data. This approach ensures that an eavesdropper with access only to the data could not decipher the key. However, researchers have recently demonstrated that even quantum encryption may be susceptible to hacking.

Calculations give initial insight into relativistic properties of this process(Phys.org) —The American Nobel Prize Laureate for Physics Richard Feynman once described turbulence as "the most important unsolved problem of classical physics", because a description of the phenomenon from first principles does not exist. This is still regarded as one of the six most important problems in mathematics today. David Radice and Luciano Rezzolla from the Max Planck Institute for Gravitational Physics (Albert Einstein Institute/AEI) in Potsdam have now taken a major step toward solving this problem: For the first time, a new computer code has provided relativistic calculations that give scientists a better understanding of turbulent processes in regimes that can be found in astrophysical phenomena.

This is shown by a study carried out by two professors at the University of Malaga (Spain), who have succeeded in solving classic problems using just such an innovative procedure.
