A Security Scheme Based on Intranal-Adding Links for Integrated Industrial Cyber-Physical Systems.

Area of Science:

• Cyber-Physical Systems
• Network Security
• Industrial Internet

Background:

• Industrial Cyber-Physical Systems (CPS) are complex, interdependent networks facing cascading failure risks.
• The integration of industrial CPS is growing in the Internet of Everything era.

Purpose of the Study:

• To propose a security scheme for integrated industrial CPS environments.
• To analyze and mitigate the risk of cascading failures in industrial CPS.

Main Methods:

• Calculating the largest connected component to assess security under random attacks.
• Comparing cascading failure risks across different intranal-adding link strategies.
• Simulating and verifying the effectiveness of proposed security strategies.

Main Results:

• The proposed intranal-adding links security scheme effectively enhances industrial CPS security.
• A specific exchange strategy demonstrated superior performance in mitigating cascading failures.
• Simulation results validated the effectiveness of the security strategy.

Conclusions:

• The developed security scheme and link strategies can optimize industrial CPS topology.
• This research provides insights for designing more resilient and secure industrial CPS.
• The findings are crucial for managing risks in increasingly integrated industrial systems.
