In the computer printer business, everyone knows the big money comes from the sale of ink cartridges.
Most of these cartridges are made by printer manufacturers and sell for a substantial premium. Some come from unauthorized sources, sell for substantially less and attract the attention of antipiracy lawyers.
The strength of the encryption now used to protect banking and e-commerce transactions on many websites may not be effective in as few as five years, a cryptography expert has warned after completing a new distributed-computing project.
Arjen Lenstra, a cryptology professor at the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland, says the distributed computation project, conducted over 11 months, achieved the equivalent in difficulty of cracking a 700-bit RSA encryption key, so it doesn’t mean transactions are at risk — yet.
The ongoing war between content producers and hackers over the AACS copy protection used in HD DVD and Blu-ray discs produced yet another skirmish last week, and as has been the case as of late, the hackers came out on top. The hacker "BtCB" posted the new decryption key for AACS on the Freedom to Tinker web site, just one day after the AACS Licensing Authority (AACS LA) issued the key.
The cat and mouse game between the hackers and the AACS Licensing Authority continues as the latest MKB v3 Processing Key is released onto the web.
A BOFFIN in the former Spanish colony of Texas has come up with a simple way of making electronic messages that are impossible to crack.
According to New Scientist, Laszlo Kish at Texas A&M University in College Station has come up with a cunning plan that uses the thermal properties of a simple wire to create a secure communications channel which outperforms quantum cryptography keys. His invention uses thermal noise which is generated by the natural agitation of electrons within a conductor.
