“…A 3-of-6 code-based data encoding countermeasure was proposed for AES cipher in [21]. Both approaches [20,21] have been analyzed in [22] and were found to have prominent leakage to bit-based correlation attacks. Pour and colleagues in [23] proposed 2-of-4 encoding for use in three sets for HW and HD equalization for a SIMON cipher implementation on the microprocessor.…”

Side‐channel attacks pose an inevitable challenge to the implementation of cryptographic algorithms, and it is important to mitigate them. This work identifies a novel data encoding technique based on 1‐of‐4 codes to resist differential power analysis attacks, which is the most investigated category of side‐channel attacks. The four code words of the 1‐of‐4 codes, namely (0001, 0010, 1000, and 0100), are split into two sets: set‐0 and set‐1. Using a select signal, the data processed in hardware is switched between the two encoding sets alternately such that the Hamming weight and Hamming distance are equalized. As a case study, the proposed technique is validated for the NIST standard AES‐128 cipher. The proposed technique resists differential power analysis performed using statistical methods, namely correlation, mutual information, difference of means, and Welch's t‐test based on the Hamming weight and distance models. The experimental results show that the proposed countermeasure has an area overhead of 2.3× with no performance degradation comparatively.

“…In DPL styles, a logic bit a is represented by a 2-bit pair (a, a), where a is the complement bit of a. Hoogvorst et al was the first to attempt to create DPL styles of hardware into software [7]. Since then, several studies, such as constant XOR and look-up table-based (LUT-based) operations, have applied these schemes to symmetric ciphers [10][11][12][13][14][15][16][17][18]. Here, constant operators, such as constant XOR, are modified into operations that always hold the same HW/HD in internal process by using only assembly language.…”

With the increasing number of side-channel attacks, countermeasure designers continue to develop various implementations to address such threats. Power-balancing (PB) methods hold the number of 1s and/or transitions (i.e., Hamming weight/distance) of internal processes constant to ensure side-channel safety in an environment in which it is difficult to use random numbers. Most existing studies employed look-up tables (LUTs) to compute those operations, except for XOR and NOT operations. However, LUT-based schemes exhibit some side-channel issues in the address bits of LUTs. In this paper, we propose the application of AND and ADD operations to PB methods based on a rule that encodes 8-bit data into a 32-bit codeword without using LUTs. Unlike previous studies that employed LUTs, our proposals overcome side-channel vulnerabilities associated with the address bits and memory wastage. In addition, we evaluate the side-channel security ensured by the proposed method in comparison with that ensured by other methods. Finally, we apply our methods to SIMON/SPECK ciphers and analyze their performance by comparing them with older schemes.
