AES Sbox with alternative polynomial
The paper's tables in Appendix A are wrong.

For the entries in the first line of Table A1(a) I independently get:

0A 15 3F 2C 90 3B 19 51 FD EF 28 8C 83 A0 A7 36


and the fourth value (for input 03h) matches the OP's computation.

Note: there are fixed points (including 23h), invalidating the list of the valid additive constants, which is about the only attempt at an addition to self-citation [15] (at least, Appendix 1 table 2b appears correct and is available for free there).

Recommendation: if working on that paper is an assignment in a crypto course, question the competence or/and honesty of the assigner.
