There is a comment in wikipedia's discussion about this: http://en.wikipedia.org/wiki/Talk:Disk_encryption_theory#Issues_with_XTS
"Issues with XTS There is also an issue about the size of the filesystem encrypted with the support of XTS. This is discussed here: http://lists.alioth.debian.org/pipermail/pkg-cryptsetup- devel/2008-September/002265.html —Preceding unsigned comment added by 62.2.182.207 (talk) 19:40, 1 April 2010 (UTC) This is a misconception, since it does not apply to large filesystems (containing many data units/sectors, which are encrypted totally indepently), but to very large single data units, i.e.: The size of any single data unit should not exceed 270 bytes. The data unit size for a typical filesystem is between 512 and 64536 bytes only (29/216).93.205.111.251 (talk) 15:37, 2 April 2010 (UTC) " What is the real situation? Is a misunderstood of the XTS spec like the XEX spec when doing XTS? If yes, the XTS crypt of very large volumes warning is not necessary. -- support AES-XTS mode https://bugs.launchpad.net/bugs/244480 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
