Mobile machinery and vehicles used for agricultural, construction, mining, and material handling purposes are currently experiencing a rapid transition from exclusively mechanical to cyber-physical systems. In order to increase the efficiency and productivity of such off-highway vehicles, electronic components with advanced connectivity are being integrated. However, these electronic systems and their interfaces introduce new cyber-security vulnerabilities.The off-highway industry is experienced in developing safe systems, but security is an emerging new field with less practice. The aim of this master thesis is to closely examine an example use case for an off-highway electronic control unit (ECU). Based on the identified cyber-security threats identified by aThreat Analysis and Risk Assessment (TARA), a security concept is developed, implemented and evaluated. The security requirements resulting from the risk assessment are refined and solutions to minimize the threats and increase cyber-security are presented. Appropriate cryptographic primitives for such an embedded system are selected. For the off-highway ECU an embedded software solution is developed. The ECU contains an automotive microprocessor with an additional security co-processor. The software solution consists of two programs, one executed on the main core of the microprocessor and one running on the microprocessor’s security co-processor. The software implemented for this thesis aims to mitigate the security threats and to make use of hardware accelerations provided by the security co-processor. The performance of the implementation is evaluated.
