Trustworthiness for an Ultra-Wideband Localization Service

Area of Science:

• Cyber-Physical Systems
• Internet of Things
• System Security

Background:

• Assuring system trustworthiness is critical for interdependent systems, especially under adverse conditions.
• Ultra-wideband (UWB) self-localization systems require robust trustworthiness assessment for reliable operation.
• Existing methods may not holistically address the multifaceted nature of system trustworthiness.

Purpose of the Study:

• To propose a holistic trustworthiness assessment framework for UWB self-localization.
• To define trustworthiness indicators based on objective evidence and threat analysis.
• To provide a versatile template for trustworthiness evaluation in IoT and cyber-physical systems.

Main Methods:

• Developed a framework encompassing reliability, security, privacy, and resilience attributes.
• Conducted threat analysis to identify and select relevant trustworthiness indicators.
• Performed experimental evaluations to validate the framework's effectiveness.

Main Results:

• The proposed framework effectively evaluates UWB self-localization trustworthiness.
• Trustworthiness indicators were successfully mapped to specific real-world threats.
• Experimental results demonstrated the practical efficacy of the assessment method.

Conclusions:

• The holistic framework provides a structured approach to UWB self-localization trustworthiness.
• The methodology ensures indicators are directly linked to identified system threats.
• The framework's adaptable nature allows for application in broader IoT and cyber-physical domains.
