Second-Order Low-Randomness $d+1$ Hardware Sharing of the AES

ePrint Report: Second-Order Low-Randomness $d+1$ Hardware Sharing of the AES

Siemen Dhooghe, Aein Rezaei Shahmirzadi, Amir Moradi

In this paper, we introduce a second-order masking of the AES using the minimal number of shares and a total of 1268 bits of randomness including the sharing of the plaintext and key. The masking of the S-box is based on the tower field decomposition of the inversion over bytes where the changing of the guards technique is used in order to re-mask …
