3 Introduction A work for the efficient software implementation of AES. Optimised software implementation (in C) oriented to 32bit platforms with low memory (e.g. embedded systems). Evaluation of the time performances on various platforms: ARM, ST and Pentium. Comparison with the time performances of Gladman s C code. The usage of lookup tables is limited: only the SBOX S and the inverse SBOX S transformations are tabularised (2 256 bytes). 08/09/2002 CHES 2002 Workshop Redwood City (SF Bay), CA, USA pp. 2 / 23
4 Algorithm Description  General Rijndael is the selected (NIST competition) algorithm for AES (Advanced Encryption Standard). It is a block cipher algorithm, operating on blocks of data. It needs a secret key, which is another block of data. Performs encryption and the inverse operation, decryption (using the same secret key). It reads an entire block of data, processes it in rounds and then outputs the encrypted (or decrypted) data. Each round is a sequence of four inner transformations. The AES standard specifies 128bit data blocks and 128 bit, 192bit or 256bit secret keys. 08/09/2002 CHES 2002 Workshop Redwood City (SF Bay), CA, USA pp. 3 / 23

8 Optimisation The Idea To improve the time performances of AES, a transposed state array has been used. state transposed state s 0 s 1 s 4 s 5 s 8 s 9 s 12 s 13 s 0 s 4 s 1 s 5 s 2 s 6 s 3 s 7 s 2 s 6 s 10 s 14 s 8 s 9 s 10 s 11 s 3 s 7 s 11 s 15 s 12 s 13 s 14 s 15 Very simple idea, but yields interesting consequences! 08/09/2002 CHES 2002 Workshop Redwood City (SF Bay), CA, USA pp. 7 / 23
9 Optimisation  Consequences The following round transformations are essentially invariant with respect to transposition (and their speed is unchanged): SubBytes ShiftRows AddRoundKey (but the round keys must be transposed) Instead, the MixColumns transformation must be completely restructured. The new MixColumns is considerably spedup by the transposition of the state. 08/09/2002 CHES 2002 Workshop Redwood City (SF Bay), CA, USA pp. 8 / 23
10 Old MixColumns It is a matricial product (in GF(2 8 )): Mix Column number c (0 c 3) s s s s 0, c 1, c 2, c 3, c = s s s s 0, c 1, c 2, c 3, c In C language a macro is used: fwd_mcol(x) state column (f2 = FFmulX(x), f2^upr(x^f2,3)^upr(x,2)^upr(x,1)) 08/09/2002 CHES 2002 Workshop Redwood City (SF Bay), CA, USA pp. 9 / 23
11 Old MixColumns  Cost s s s s 0, c 1, c 2, c 3, c = 02 s s s s 0, c 1, c 2, c 3, c s s 03 s s 3, c 0, c 1, c 2, c s s s s 2, c 3, c 0, c 1, c s s s s 1, c 2, c 3, c 0, c The cost per column is: a single doubling, 4 additions (XOR) and a 3 rotations (all operations work on 32 bits). For a complete MixColumns transformation 4 doublings, 16 additions ions (XOR) and 12 rotations are required. doubling means 4 multiplications in GF(2 8 ) of each byte of the 32bit word. 08/09/2002 CHES 2002 Workshop Redwood City (SF Bay), CA, USA pp. 10 / 23
12 New MixColumns s 0 s 1 s 2 s 3 s 4 s 5 s 6 s 7 s 8 s 9 s 10 s 11 s 12 s 13 s 14 s s 0 s 1 s 2 s 3 s 4 s 5 s 6 s 7 s 8 s 9 s 10 s 11 s 12 s 13 s 14 s 15 s 0 s 4 s 8 s 12 [ ] s 0 s 1 s 2 s 4 s 5 s 6 s 8 s 9 s 10 s 12 s 13 s 14 state row s 3 s 7 s 11 s 15 Transposition is equivalent to processing the state array by rows, instead of processing it by columns! 08/09/2002 CHES 2002 Workshop Redwood City (SF Bay), CA, USA pp. 11 / 23
13 New MixColumns The New MixColumns transformation is: y 0 = ({02} x 0 ) + ({03} x 1 ) + x 2 + x 3 y 1 = x 0 + ({02} x 1 ) + ({03} x 2 ) + x 3 y 2 = x 0 + x 1 + ({02} x 2 ) + ({03} x 3 ) y 3 = ({03} x 0 ) + x 1 + x 2 + ({02} x 3 ) The symbols x i and y i (0 i 3) indicate the 32bit rows of the state array before and after New MixColumns, respectively. The 32bit word x i accommodates 4 bytes coming from 4 different columns (and similarly for y i ). The operation {02} x i or doublings consists of 4 multiplications in GF(2 8 ) of each byte of the 32bits word. 08/09/2002 CHES 2002 Workshop Redwood City (SF Bay), CA, USA pp. 12 / 23
14 New MixColumns The transformation can be executed in three steps. It can be conceived as a sort of double and add algorithm. 5HPDLQGHU y 0 = x 1 + x 2 + x 3 y 1 = x 0 + x 2 + x 3 y 2 = x 0 + x 1 + x 3 y 3 = x 0 + x 1 + x 2 x 0 = {02} x 0 x 1 = {02} x 1 x 2 = {02} x 2 x 3 = {02} x 3 y 0 += x 0 + x 1 y 1 += x 1 + x 2 y 2 += x 2 + x 3 y 3 += x 3 + x 0 08/09/2002 CHES 2002 Workshop Redwood City (SF Bay), CA, USA pp. 13 / 23
15 MixColumns Cost Comparison The standard implementation of MixColumns requires: 4 doublings, 16 XOR s and 12 rotations, and one intermediate variable The transposed version of MixColumns requires: 4 doublings, 16 XOR s and NO rotation, and NO intermediate variable. Software time performances should improve! 08/09/2002 CHES 2002 Workshop Redwood City (SF Bay), CA, USA pp. 14 / 23
16 Decryption Decryption uses the InvMixColumns transformation inverse of MixColumns. Also InvMixColumns can be spedup by the transposition of the state array. Transposition yields a higher speedup for InvMixColumns than for MixColumns. This is due to the complex structure of the coefficient matrix of InvMixColumns. Mixcolumns coeff.s:, 02 and 03 (hex). InvMixColumns coeff.s: 09, 0b, 0d and 0e (hex). 08/09/2002 CHES 2002 Workshop Redwood City (SF Bay), CA, USA pp. 15 / 23
17 Old InvMixColumns s s s s 0, c 1, c 2, c 3, c = 0e 09 0d 0b 0b 0e 09 0d 0d 0b The entries of the coefficient matrix of InvMixColumns contain a larger number of 1 s than those of MixColumns. Transposition exposes more parallelism and hence yields a significant speedup. 0e d 0b 0e s s s s 0, c 1, c 2, c 3, c 08/09/2002 CHES 2002 Workshop Redwood City (SF Bay), CA, USA pp. 16 / 23

19 InvMixColumns Cost Comparison The standard algorithm requires: 12 doublings, 32 XOR s and 12 rotations, and 4 intermediate variables. The transposed algorithm requires only: 7 doublings, 27 XOR s and NO rotation, and NO intermediate variable. Software time performances should improve! But time performances should improve in hardware as well! 08/09/2002 CHES 2002 Workshop Redwood City (SF Bay), CA, USA pp. 18 / 23
20 Time Performances The time performances of the proposed algorithm have been tested on some 32bit CPU s: ARM 7 TDMI and ARM 9 TDMI, typical microcontrollers ST 22, a CPU designed for smart card (by STM) and PENTIUM III, a general purpose CPU The time performances are computed in CPU cycles, and are compared with those of Gladman s C code. Where Gladman is better, it is due to the time overhead required to transpose input and output data, to remain compliant with the standard. 08/09/2002 CHES 2002 Workshop Redwood City (SF Bay), CA, USA pp. 19 / 23
