A Distributed and Secure Self-Sovereign-Based Framework for Systems of Systems

Area of Science:

• Computer Science
• Information Security
• Cybersecurity

Background:

• Security and privacy are critical challenges in complex systems of systems (SoS).
• Traditional security models struggle to address the unique vulnerabilities of interconnected systems.
• Emerging technologies like distributed ledger technology (DLT) and self-sovereign identity (SSI) offer potential solutions.

Purpose of the Study:

• To propose a novel distributed and self-sovereign-based framework for enhancing security and privacy in systems of systems.
• To address the limitations of traditional security approaches in SoS environments.
• To establish a secure and privacy-preserving identity management system for SoS.

Main Methods:

• Development of a distributed framework integrating DLT and SSI principles.
• Extensive security analysis using a threat model based on the STRIDE framework.
• Comparative analysis against traditional SoS security measures.

Main Results:

• The proposed framework significantly enhances the security of systems of systems.
• User privacy is effectively maintained through self-sovereign identity integration.
• The STRIDE-based threat model analysis confirms the framework's mitigation capabilities.

Conclusions:

• The proposed framework is feasible and effective for securing systems of systems.
• DLT and SSI integration provide a robust solution for identity management in SoS.
• The framework establishes a new standard for secure and privacy-preserving SoS architectures.
