Alejandro Abdelnur commented on HDFS-6134:
------------------------------------------

[~hitliuyi], on the why we need the IV in the proposed new methods. We need an 
IV because  EDEKs are transient from the KeyProvider perspective.

> Because of privacy and security regulations, for many industries, sensitive 
> data at rest must be in encrypted form. For example: the health­care industry 
> (HIPAA regulations), the card payment industry (PCI DSS regulations) or the 
> US government (FISMA regulations).
> This JIRA aims to provide a mechanism to encrypt HDFS data at rest that can 
> be used transparently by any application accessing HDFS via Hadoop Filesystem 
> Java API, Hadoop libhdfs C library, or WebHDFS REST API.
> The resulting implementation should be able to be used in compliance with 
> different regulation requirements.
