The future is that drive-based FDE will become a commodity, probably within the next 2-3 years. All drives will likely have this capability. The key (no pun!) is authentication and key management, which of course is software-based. That is why we have teamed with Seagate.

As I read the tea leaves, the doubling time for CPU is, per Moore's Law, 18 months but circa 12 months for disk. Ipso facto, the ratio of CPU to disk in a constant-dollar design regime must fall at the rate of an order of magnitude per decade, or a CAGR for the inverse ratio of disk/CPU of 26%/annum. For the CPU side to keep up, either the fraction of total retained data actually handled per unit time has to fall, or the number and/or percentage of CPUs devoted to encryption must rise. I suspect this drives the encryption into the disk enclosure quite inexorably. --dan _______________________________________________ FDE mailing list [email protected] http://www.xml-dev.com/mailman/listinfo/fde _______________________________________________ FDE mailing list [email protected] http://www.xml-dev.com/mailman/listinfo/fde
