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:
