Re: [STDS-P1619] Enterprise Storage Forum article gives P1619/.1/.3 a good review
Dear Matt,
We see the statement below repeated in different forums:
"The only negative feedback I've heard about IEEE 1619 is by a large hard
disk manufacturer that does not believe the encryption mode is suitable for
hard disks," said Ball.
If you refer to Seagate's comments, it is not the right interpretation. We
meant that P1619 was designed for transparent (external) encryption
modules, which keeps the data layout unchanged. The standard text itself
says that. For disk encryption there is no need for keeping the data layout
unchanged, therefore we have a much larger choice of tools. The security
model is also different: we can trivially prevent the access to the
ciphertext, except after destructing the drive. This one-time ciphertext
access allows simpler, faster encryption modes.
Therefore, P1619 is "suitable", only not *optimal* for disk drives.

Hi All,
Drew Robb just published a very positive article on the P1619-series
standards:
