             Summary: Support TDE(Transparent Data Encryption) for Ozone
                 Key: HDDS-1041
                 URL: https://issues.apache.org/jira/browse/HDDS-1041
             Project: Hadoop Distributed Data Store
          Issue Type: New Feature
          Components: Security
            Reporter: Xiaoyu Yao
            Assignee: Xiaoyu Yao


Currently ozone saves data unencrypted data on datanode, this ticket is opened to support TDE(Transparent
Data Encryption) for Ozone to meet the requirement of use cases that need protection of sensitive
data.

The table below summarize the comparison of HDFS TDE and Ozone TDE: 

 
||HDFS||Ozone||
|Encryption zone created at directory level.
All files created within the encryption zone will be encryption.
 
|Encryption enabled at Bucket level.
All objects created within the encrypted bucket will be encrypted. 
 
|
|Encryption zone created with ZK(Zone Key)|Encrypted Bucket created with BEK(Bucket Encryption
Key)|
|Per File Encryption  
* File encrypted with DEK(Data Encryption Key)
* DEK is encrypted with ZK as EDEK by KMS and persisted as extended attributes.|Per Object
Encryption
* Object encrypted with DEK(Data Encryption Key)
* DEK is encrypted with BEK as EDEK by KMS and persisted as object metadata.|

I will post a design doc shortly.
