Prepare for Secure Blue
by Joris Evers
Researchers at IBM have come up with a way to hard wire encryption technology into a microprocessor, promising a more secure way to store data.
IBM plans to announce availability of the new technology, dubbed Secure Blue. The company envisions its idea and technology will be used in digital media players, electronic organizers, cell phones, computers and devices used by the government, medical and financial services industry.
With Secure Blue, data is encrypted and decrypted as it runs through processor, according to IBM. It is maintained encrypted in the device memory, or RAM. One of the few times data would not be scrambled is when it is actually displayed.
Charles Palmer, manager security and privacy at IBM, said: "There is a lot of concern about leakage of data. If you have an architecture where that information is always encrypted, you go a long way to protect your data."
Secure Blue requires a few circuits to be added to a microprocessor, taking up a few per cent of the overall silicon real estate, according to IBM. The encryption and decryption happens on-the-fly, without any processor overhead, the company said.
