You don't.

Well, you can look in the css.c / ioctl.c file of libdvdcss for
functions that return the 'security key sector'.  I don't think
it will do you a whole lot of good, though.  I might be wrong but
I don't think you can burn that sector to a writeale DVD anyway.. 
it's not part of the regular data track.  
Why would you want to have it?  Doesn't dvdbackup descramble the 
data when extracting it?

Well that is because we're one and the same (or well almost anyway).
