You can use a regular block filesystem on top of UBI using the block
interface (drivers/mtd/ubi/block.c), and then use standard encrypt stuff
for block devices (dm-crypt for instance).
However, this has nothing to do with UBIFS, so maybe it's not an option for you.
If the filesystem you want to encrypt is read-only, then you may consider
the UBI block option.
Hope it helps,
