ADVANCED ENCRYPTION TECHNIQUES FOR INDUSTRIAL IOT AND CONTROL SYSTEMS

Abstract

The increasing integration of Industrial Internet of Things (IIoT) and Industrial Control Systems
(ICS) into critical infrastructure has led to significant advancements in automation, data analysis,
and operational efficiency. However, this connectivity also introduces vulnerabilities and cyber
threats, which necessitate robust security measures. Among these, encryption plays a crucial role
in securing communication channels and protecting sensitive data from unauthorized access and
tampering. This paper explores advanced encryption techniques for IIoT and ICS, focusing on
their effectiveness in safeguarding industrial networks. Various cryptographic methods, including
symmetric, asymmetric, and hybrid encryption, are evaluated for their applicability in industrial
environments. Additionally, quantum-resistant algorithms are also discussed, considering the
growing potential of quantum computing to break traditional encryption methods. The research
highlights the need for encryption standards tailored to the unique requirements of industrial
systems, such as low latency, high throughput, and scalability. The study also proposes a set of
best practices for implementing encryption across IIoT and ICS, providing insights into future
trends and challenges.
