RSA-640 Factored

Schneir reports that RSA-640 has been factored.

Some links to follow up. Note that this isn't RSA-1024 by any means, but it continues to highlight that relying upon today's strong crypto may not guarrantee data security in 20 years time.

From one of these reports:

      The factorization of the latest RSA number to fall involved "lattice" sieving 
      done by J. Franke and T. Kleinjung using hardware at the Scientific Computing 
      Institute and the Pure Mathematics Institute at Bonn University, Max Planck   
      Institute of Mathematics in Bonn, and Experimental Mathematics Institute in 
      Essen. The factorization of RSA-640 was accomplished using a prime 
      factorization algorithm known as the general number field sieve. Sieving was 
      done on 80 2.2-GHz Opteron CPUs and took 3 months. The matrix step was 
      performed on a cluster of 80 2.2-GHz Opterons connected via a Gigabit network  
      and took about 1.5 months.

Not trivial compute power, but not out of the reach of people with lots of machines, or lots of money. Can you say university lab supervisor?

Practical Implications: Use RSA-2048 as a minimum for any new keys. Review the sensitivity of the data you are protecting with RSA-1024 and re-encrypt if you need longer term security.

LCA2006 programme available

The programme for linux.conf.au 2006 is now available. And there's some surprises in there for those who've been before - 8 simultaneous miniconfs, and 6 streams including seminars and tutorials running side-by-side. More value for money every year. And I know of a few surprises that the conference program doesn't show :-)

Just remember, there's only 7 days of early bird registration still available. Don't you think it's time you registered to come to this great Australasian tradition? :-)

linux.conf.au 2006. Dunedin, New Zealand. 23rd - 28th January 2006 - Register now!!!
