Hybrid Technique for Cyber-Physical Security in Cloud-Based Smart Industries

Area of Science:

• Cyber-Physical Systems (CPS)
• Internet of Things (IoT)
• Industrial Cybersecurity

Background:

• CPSs in smart industries face significant security challenges due to their integration with IoT and cloud infrastructure.
• The heterogeneous nature of devices and interconnectedness of cyber and physical layers create vulnerabilities in traditional CPS security.
• Existing security measures are often insufficient for Complex Industrial Applications (CIA) involving dynamic interactions.

Purpose of the Study:

• To propose a novel data security algorithm, Dynamic Hybrid Secured Encryption Technique (DHSE), for enhancing CPS security.
• To address the security constraints posed by cloud-based data storage in IoT-enabled CPS.
• To improve the efficiency of data encryption and decryption in industrial cyber-physical systems.

Main Methods:

• Developed a hybrid encryption scheme combining Advanced Encryption Standard (AES), Identity-Based Encryption (IBE), and Attribute-Based Encryption (ABE).
• Implemented data categorization into less sensitive, mid-sensitive, and high sensitive levels.
• Utilized named-data packets (NDPs) with name labeling for data distribution and defined encryption rounds based on key size.

Main Results:

• The DHSE algorithm demonstrated an average encryption time of 2.07 ms, significantly faster than AES (3.25 ms), IBE (2.18 ms), and ABE (2.39 ms).
• Average decryption times for DHSE were 1.07 ms, outperforming AES (1.77 ms), IBE (1.09 ms), and ABE (1.20 ms).
• The proposed framework ensures data confidentiality with minimal encryption and decryption overhead.

Conclusions:

• The DHSE algorithm provides a robust and efficient solution for securing data in CPS-IoT environments.
• The hybrid approach effectively balances security and performance, making it suitable for complex industrial applications.
• DHSE's speed and confidentiality features are critical for the continued development and adoption of smart industries.
