Lausanne, Switzerland (GenevaLunch) - Mathematicians at EPFL, the Swiss federal polytechnic institute, used a cluster of more than 200 PlayStation 3 game consoles to spend six months solving an encryption problem, breaking a previous record set in 2002. The laboratory for cryptologic algorithms cracked a 112-bit encryption based on elliptical curves. The significance of the work is that it “may serve to boost our confidence in the strength of elliptic curve cryptography (ECC),” say the authors, led Joppe Bos and Marcelo Kaihara. Encryption is widely used in banking and other industries for security. The encryption industry struggles to stay ahead of code-cracking hackers, who are using increasingly sophisticated methods and calculators.
A 160-bit elliptical curve standard is scheduled to be phased out by the industry in 2010, but the EPFL calculation shows that “for the next decade no regular user needs to be overly concerned about the security of 160-bit ECC.”
