Towards a Low-Cost Remote Memory Attestation for the Smart Grid.

Area of Science:

• Cybersecurity
• Smart Grid Technology
• Network Security

Background:

• Smart grid measurement devices are vulnerable to adversarial attacks, compromising operations.
• Existing remote attestation schemes for detecting compromised devices are sensitive to network delays, leading to high overhead.
• There is a need for efficient and accurate detection methods that account for real-time network conditions.

Purpose of the Study:

• To propose a low-cost remote memory attestation scheme (LRMA) for efficiently and accurately detecting compromised smart meters.
• To address the limitations of existing schemes by considering real-time network delay and reducing computation and network overhead.
• To enhance the security and reliability of smart grid infrastructure.

Main Methods:

• Developed a low-cost remote memory attestation scheme (LRMA).
• Utilized time differences reported from relay nodes to eliminate the impact of real-time network delay.
• Dynamically adjusted attestation frequency based on the compromised probability of each node.

Main Results:

• LRMA efficiently and accurately detects compromised smart meters.
• The scheme effectively eliminates the impact of real-time network delay on detection.
• Achieved lower computation and network overhead compared to existing schemes.
• Demonstrated better detection capacity through theoretical analysis and evaluations.

Conclusions:

• LRMA offers an effective solution for detecting compromised devices in smart grids.
• The proposed scheme provides a balance between detection accuracy and resource efficiency.
• LRMA enhances smart grid security by providing a robust and low-overhead attestation process.
