Google Looking at the past few week of Google news, you'll be forgiven for thinking Google doesn't do anything else beyond making Android. While there's sexier stuff going on within Google, the company is also still trying to improve its core user service: search. They've launched encrypted search today, and it will be rolled out across the world in the coming days.

It's called homomorphic encryption ( http://en.wikipedia.org/wiki/Homomorphic_encryption ). Basically, yes, there exist encryption systems such that a remote computer can be given encrypted data and an arbitrary program, convert the program to run on encrypted data, run it, and send back an encrypted result without ever knowing anything about the encrypted data. As that article mentions, such cyptosystems are very recent (the first one was discovered less than a year ago), and their efficiency makes them impracticably slow for many (most?) applications.
