Substitution Box Construction Using Transfer‐Function Assisted Metaheuristic and Booster Algorithm: A Hybrid Approach

Security and Privacy, Год журнала: 2024, Номер unknown

Опубликована: Сен. 26, 2024

ABSTRACT S‐box strengthens the encryption and decryption process by introducing nonlinearity protecting encrypted data against various differential linear cryptanalytic attacks. Generating a highly nonlinear with maximal is computationally impractical due to expansive search space, classifying it as an NP‐hard problem. This paper proposes Hawkboost algorithm, novel hybrid method merging Harris Hawks optimization algorithm (HHO) Booster for generating S‐boxes low computational efforts. The HHO utilized navigate in large permutation space find acceptable cryptographic properties. assisted Transfer function Random Key (RK) speed up design process. Additionally, enhances applying random local operators like swap inversion, effectively reshaping elements of S‐box. combination methodologies facilitates efficient generation that exhibit excellent properties while addressing key challenges optimization. performance proposed has been analyzed comparing state‐of‐the‐art based on numerous characteristics including average nonlinearity, strict Avalanche criterion (SAC), SAC offset, bit independence (BIC), approximation probability (LP), (DP), fixed points, opposite cycle counts. results from experiments analysis multiple metrics show satisfies all requirements safe reliable without sacrificing any crucial security features.
