Abstract: With the widespread use of electronic toll collection (ETC) systems, the cybersecurity risks are also increasing. In order to solve the problem of cybersecurity risk assessment of on-board units in ETC, the paper proposes a cybersecurity assessment framework for on-board units. The framework uses threat analysis to systematically analyze the potential threats faced by on-board units. Risk assessment is used to grade the potential threats. While, test cases are utilized to identify and verify the cybersecurity risk. Experiments show that the cybersecurity assessment framework can perform effective cybersecurity assessment on on-board units in ETC to identify potential cybersecurity risks, which provides an effective reference for protecting subsequent product.
