REDUNDANCY AES MASKING BASIS FOR ATTACK MITIGATION USING LOOKUP TABLES

原文（中国語）

Techniques include replacing many of the functions used in finite-field-based arithmetic with lookup tables (LUTs) and combining such LUTs with redundancy-based protection. Advantageously, using LUTs makes it possible to dramatically decrease the redundancy level (e.g., from d=8 to d=3 or 4) and the power consumption and increase the maximal frequency, while preserving the same protection level, latency and performance. The improvement is applicable not only to AES, but also to other algorithms based on a finite field arithmetic, and in particular SM4, ARIA, and Camellia which use Sboxes very similar to or the same as the AES Sbox.
