New record in the area of prime number decomposition of cryptographically important numbers

08.01.2010
An international team of scientists from EPFL (Switzerland), INRIA (France), NTT (Japan), CWI (The Netherlands) and Bonn University (Germany), has obtained the prime factors of the RSA challenge number RSA-768, using the Number Field Sieve. The calculation took less than 2000 core years on modern CPUs.

Extrapolating the trend from previous records in this area (512-bit in 1999, 663-bit in 2005, and the current 768-bit in 2009), it is reasonable to expect that 1024-bit keys will exhibit a similar degree of vulnerability within the next decade.

The result thus underlines the importance to adopt the new cryptographic key size standards that recommend phasing out usage of currently popular 1024-bit RSA keys. However, it also indicates that, assuming similar resources, users do not incur undue risks by continued usage of 1024-bit RSA keys during the next few years of transition to higher security levels.

The software used was to a considerable extent based on a package developed in the early 2000s at the Mathematics Institute at Bonn University, and further developed by the present collaborators. EPFL's Laboratory for Cryptologic Algorithms acted as main organizer, central data collection point, and contributed approximately a third to the overall computational effort.

Im Focus: Flexible proximity sensor creates smart surfaces

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.

At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
