Encryption in the cloud

Good read on the $subject

There are solutions for data-at-rest, but they are far from perfect for cloud scenarios. In my opinion, the most challenging one is the data-in-process. There are some basic solutions to perform computation over encrypted data, but they are quite limited. This is mainly due to the fact that we still don't have efficient fully homomorphic encryption schemes. I think in the next decade, we will see better techniques to perform computation over encrypted data without decrypting them.
