Though out this document when I refer to LFSR, I am really referring to a cryptographically secure LFSR. The standard LFSR is about as secure as a teen age girl with a telephone. There are several ways to combine several LFSR's to make them secure (and many more which offer no additional security at all). Although such LFSR's are beyond the scope of this app note, there are many books written on the subject.
