Cloud Encryption How it works

Data lockdown

Cloud Encryption makes it possible to use the cloud to store and manage data but keeps the data content invisible from the cloud. This is made possible by a technology called public key encryption. Data is locked down before its is uploaded to the cloud. It is literally impossible to unlock the data without the corresponding decryption key.

How can the right person unlock the data but the wrong ones don't?

Imagine the following scenario:

1. Bob sends a box and a open padlock to Alice but keeps the key

2. Alice

a. puts data in the box
          b. locks it with Bob’s padlock
          c. sends the box back to Bob

3. Bob receives the box and opens the padlock with his key

This is not that far from how it actually works, but the box and the lock is based on math.
