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)
