See [spec] and [break] changes in reference implementation. Further changes:
-- A more synthetical organisation was chosen. Indeed, Lilliput-II only need encryption and Lilliput-I need encryption and decryption, so LilliputTBCencrypt is always used for lilliput-I and LilliputTBCencryptdecrypt for Lilliput-II. And LilliputTBCdecrypt is no longer described because no version uses it.
+- 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.
-- For Lilliput-I we change coefficients in tweakey schedule to ensure lane 0 is updated between each decryption round:
+- 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: M_R (unchanged)
+ - lane 5: M_R^2 (unchanged)
+ - lane 6: M_R^3 (unchanged)
