Information on RC5-64
RSA had issued a secret-key challenge
some time ago. Distributed.net took up the organizing of the world's fastest
computation machine by developing client software and keyserver software for every major
platform. In the initial run on the 56-bit challenge, a member of the team came up with
the correct block on the 250th day.
Each block is comprised of
268,435,456 keys. The average computation time for each block is about 40 minutes.
With the 64-bit challenge (see
identifier RC5-32/12/8) the possibilities and computations necessary have multiplied
many times. The possibilities are 2^64 or simply 1 in 68,719,476,736 blocks. Perhaps
as odd as finding that certain grain of sand at some remote beach.
The competition is to say
to the United State's Government that current encryption export standards are over-bearing
and prevent civilians and private industry from remaining secure abroad, as well as
limiting the competitiveness of U.S. companies in the global market.
It is about freedom.
To boot RSA has offered a $10,000 bounty for the holder of the key. The prize money
will be divided in accordance with the distributed.net organizers, with $8,000 going to
charity, $1,000 to the organizers, and the remaining $1,000 going to the key holder.
