 See [spec] and [break] changes in reference implementation. Further changes:
 
-- A simpler file organization was chosen. Lilliput-II only needs encryption, while Lilliput-I needs encryption and decryption, so LilliputTBCencrypt is always used for Lilliput-I and LilliputTBCencryptdecrypt for Lilliput-II. LilliputTBCdecrypt is no longer described because no version uses it.
+- Each algorithm variant now contains a single VHDL implementation, add_vhdltbc:
+    - for Lilliput-I variants, add_vhdltbc corresponds to the former add_vhdltbcencryptdecrypt,
+    - Lilliput-II variants do not need the decryption part of Lilliput-TBC, therefore add_vhdltbc corresponds to the former add_vdhltbcencrypt.
 
 - For Lilliput-I, the inverted multiplications have been updated to match changes to the encryption process:
     - lane 0: Id       => inv(M)
     - lane 1: inv(M)   => inv(M)^2
     - lane 2: inv(M)^2 => inv(M)^3
     - lane 3: inv(M)^3 => inv(M)^4
-    - lane 4: M_R   (unchanged)
-    - lane 5: M_R^2 (unchanged)
-    - lane 6: M_R^3 (unchanged)
+    - lane 4: inv(M_R)   (unchanged)
+    - lane 5: inv(M_R)^2 (unchanged)
+    - lane 6: inv(M_R)^3 (unchanged)
