Re: Security Theater Only
It's easy to keep a secret if the only person you need to share it with is you.
So Microsoft can make a perfectly secure system where you have the keys, you encrypt it, they store and you decrypt it. That's great if the only use of the cloud is as a great big disk drive in the sky.
As soon as you need somebody else to process it then you need to share keys and unless you trust them you are screwed - whatever the technology, especially if you know the NSA is looking over their shoulder
