[curves] Generalized Mersenne Numbers

[Antonio Sanso]

hi *,

The Solina's paper Generalized Mersenne Numbers (also used in some ECC standard) [0] contains a Linear Feedback shift register I am not able to understand.
You can find the lfsr i am talking about at page 4 of the paper [0] or simply in this question I made in  the crypto stackexchange site.

It is supposed to be a normal Linear Feedback shift register but it doesn't seem to follow the "normal" lfsr rule. Is anyone able to explain the logic it follows?

Thanks in advance

antonio
