> IV misuse in commit log encryption
> ----------------------------------
>
> Key: CASSANDRA-11809
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11809
> Project: Cassandra
> Issue Type: Bug
> Reporter: Blake Eggleston
> Priority: Major
> Fix For: 3.11.x
>
>
> Commit log segments share iv values between encrypted chunks. The cipher
> should be reinitialized with a new iv for each discrete piece of data it
> encrypts, otherwise it gives attackers something to compare between chunks of
> data. Also, some cipher configurations don't support initialization vectors
> ('AES/ECB/NoPadding'), so some logic should be added to determine if the
> cipher should be initialized with an iv.
