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.

Encryption Space Operators

This seems like an idea:

That is, the target data is encrypted, as are your commands/operators. The only plain text space is within your perimeter.

This means if someone has access to the target data, it is meaningless. Similarly, what you do with it (transform, query, reduce, etc) is also meaningless as the operations/programs are encrypted too, even while they operate on the encrypted data.

This would solve some of the security fears around cloud computing.

Nice idea - could it be implemented? Or is there a theoretical reason this can't be done?
