Cryptography Role in Industry 4.0 Through Privacy of Data and Communications using Hybrid Encryption Algorithms

Cryptography plays a crucial role in Industry 4.0, safeguarding the security and privacy of data and communications within highly interconnected and automated industrial systems. As vast amounts of data are generated and transmitted across devices, systems, and cloud platforms, cryptographic methods are essential for ensuring data confidentiality and restricting access to authorized entities. This paper introduces two novel hybrid encryption algorithms: modified HIGHT-Simon and modified HIGHT-Trivium, which integrate the lightweight HIGHT cipher with Simon and Trivium ciphers, respectively. Both algorithms are evaluated across three configurations with different rounds 8,10, and 12 to assess their encryption and decryption performance. The results reveal that the modified HIGHT-Simon algorithm consistently achieves faster encryption and decryption times, making it ideal for real-time applications in Industry 4.0, such as industrial IoT and smart manufacturing systems, where both speed and security are critical. In contrast, the modified HIGHT-Trivium algorithm, while providing a more balanced encryption-decryption process, exhibits slower performance, making it better suited for applications that prioritize security over speed. Overall, the modified HIGHT-Simon algorithm emerges as the more efficient solution for ensuring both privacy and rapid data communication in the fast-paced, data-intensive environments of Industry 4.0.
