-/**
-* Definition 1 (Cipher state). A cipher state of iClass s is an element of F 40/2
-* consisting of the following four components:
-* 1. the left register l = (l 0 . . . l 7 ) ∈ F 8/2 ;
-* 2. the right register r = (r 0 . . . r 7 ) ∈ F 8/2 ;
-* 3. the top register t = (t 0 . . . t 15 ) ∈ F 16/2 .
-* 4. the bottom register b = (b 0 . . . b 7 ) ∈ F 8/2 .
