IBM and Microsoft researchers to make software unhackable?

The idea of obfuscating a program has been around for decades — software companies have tried all sorts of methods to distort their code in order to prevent others from seeing how it worked. However, the security and hacking communities have been able to defeat all these measures. Cryptographic experts have long been tinkering with stronger approaches, but it wasn’t until the most recent collaboration that the pieces started falling into place.

Cryptographers have been chasing the idea of a so-called “black box obfuscator” for years. The idea is that any program passed through the black box would be so fundamentally garbled that no one would be able to figure out how it worked or what secrets it might hold — only inputs and outputs would be visible, which is exactly what you want. This method could make communications almost completely secure. All you would need to do is create encryption keys with an obfuscated program, then make that program available to the other party — or everyone for that matter, since no one would be able to figure out the decryption key from examining the obfuscated program.
