Further changes: + +- 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: inv(M_R) (unchanged) + - lane 5: inv(M_R)^2 (unchanged) + - lane 6: inv(M_R)^3 (unchanged) + (inv_multiplication.vhd) + +- Merge Sbox in one file. + (sbox.vhd, inner_sbox_a.vhd, inner_sbox_b, vhd,inner_sbox_c.vhd) + +- Create registers in file roundexe_lilliput.vhd. + (state_key_register.vhd, state_register.vhd, roundexe_lilliput) + +- Reduction of the number of signals. + (chiffrement.vhd) + +- Add self-checking testbench. + (top_tb.vhd) + +- Pipeline RoundTweakey extraction and round function. + (roundexe_lilliput.vhd, machine_etat_chiffrement.vhd) + +- Isolate input and output from critical path. + (roundexe_lilliput.vhd, machine_etat_chiffrement.vhd) v1 |
