Suppressed Texas Instruments cryptographic signing keys, 28 Aug 2009
Texas Instruments, a large US electronics company, is the market
leader for sophisticated programable calculators used by millions of
students and engineers. Recently, TI has served internet publishers
with DMCA legal threats for distributing cryptographic keys that
permit owners of TI calculators to install third-party system software
on TI calculators -- an anti-competitive, and arguably unethical act
by TI.
The file here presents the Operating System signing keys for different
Texas Instruments calculators. The key for the TI-83 calculator was
first published by someone at the unitedti.org forum [1]. He or she
needed several months to crack it. The other keys were found after a
few weeks by the unitedti.org community through a distributed
computing project. The keys make it possible for people to create new
OS software to be used on Texas Instruments calculators.
Texas Instruments contacted several people with DMCA notices to take
down the keys from their websites. Some of the websites which got a
DMCA notice are: unitedti.org, brandonw.net and reddit.com. One of
these DCMA notices can be found here: http://brandonw.net/calcstuff/DMCA_notice.txt
