Attribute-based encryption for cloud storage I'm trying to understand attribute-based encryption schemes. Almost all articles describe that they are designed for cloud storage, but as I understand, almost all computing (encryption &amp; decryption) is performed client-side and not in the cloud.

In this regard, I have a question: How are these schemes related to cloud storage?
It is related to Cloud storage in the sense that you don't have to trust the server you put your data on. 
Usually, the access control is done via authentication. This requires the server to be trusted. 
However in the case of Cloud storage, you don't know anything about the server hosting the data, so being able to do access control with the encryption scheme is great.
