The crack which was accomplished using resources at the SFI-Funded Irish Centre for High End Computing was announced at the Post-Quantum Cryptography conference in Cincinnati, USA on Saturday 18 October.
Quantum computers will break current public key algorithms such as RSA. McEliece's system is not affected by quantum computers and is a leading candidate for future public-key cryptography. The successful attack shows that the originally proposed key sizes for McEliece's system are too small and need to be increased.
The DCU success was part of a coordinated attack by cryptographers in five countries. The attack was led by Prof Tanja Lange and Christiane Peters (Eindhoven Technical University, TU/e) and Prof Daniel J Bernstein (University of Illinois at Chicago), who recently published a paper claiming that a practical attack on McEliece's system was feasible with their new software.
Costigan and Scott ran the software at ICHEC for 8000 CPU hours and achieved the first break on Wednesday 2nd October 2008. Other countries ran the software for a total of 200000 CPU hours but did not have the luck of the Irish.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
