Security enhancement for UBIFS with secure erase feature

[Stelling Carsten]

< Are there any plans for such a security enhancement in UBIFS?

Hello Atlant,

you're right. Writing zeroes is not applicable to all kinds of flash technology.

Are there any plans to support privacy in UBIFS?

In my opinion privacy should be guaranteed by the file system, so that any
application can rely on its security features.

There're other solutions, e.g. to encrypt the content of each file with a unique
key stored in the metadata area of that particular file. Although this solution
needs to secure erase the key associated with the deleted file too.
I see, that might be a real dilemma.

Are there any suggestions?

Regards,

Carsten
