11. Real Time Perfect Bit Modification Attack on In-Vehicle CAN

Abstract

The vulnerabilities of controller area network (CAN) are often targeted by various types of vehicle hacking. To this end, conventional cyber attacks have used a frame injection and a dominant bit injection. However, these two techniques cannot modify data frames sent from an electronic control unit (ECU) in real time. Thus, the frame injection cannot perfectly control the target system. The dominant bit injection can only perform denial of service (DoS) attacks, which means that it cannot perfectly control the ECU. In this article, we propose a new attack technique for modifying either dominant or recessive bits represented in a CAN bus as the attacker intends. This technique is called perfect bit modification (PBM). We introduce two attack models using the PBM technique, the bus possession attack (BPA) and the target ID attack (TIA). The BPA can perform an attack without breaking the communication pattern of the CAN bus, and the TIA can perfectly seize control of a specific ECU. In addition, we produce an attack tool with the PBM functionality using the SN65HVD230 (CAN transceiver) and the FDS8949 (MOSFET). Both SN65HVD230 and FDS8949 are components that are commonly used to build ECUs, which cost less than two dollars. This means that our attack models are likely to be utilized for supply chain attacks. To demonstrate the feasibility of BPA and TIA, we conduct attack experiments using two real vehicles. Finally, we analyze the characteristics of existing attack techniques including PBM and suggest countermeasures to construct a secure CAN environment.

Abstract

The purpose of this study is to investigate the causal relationship between in secondary physical education teachers and instructional Images junior class attitude and commitment that they recognize or experience. This environmental and high school students of the need to form the active participation and desirable attitudes to learning through physical education class enemy and proposes a range of measures that can have a positive impact on the psychological part. In addition, values of physical education teachers on education as a right educator, attitudes, and to promote the quality of physical education class by discussing such beliefs in sociological terms. Surveyed 300 people attending middle school for this, Gyeonggi two materials were used in the final analysis was a 269 unit. Data analysis was used confirmatory factor analysis, reliability analysis, correlation analysis and path analysis was performed with stepwise regression analysis. The results were derived through the above procedure as follows. First, the result was an image of a physical education teacher analyzes the impact of immersion classes, it showed a statistically significantly have a positive impact. Second, physical education teachers resulting image was analyzed the impact on teaching attitude, the image of the physical education teachers showed statistically significant positive effect on the attitude in class. Third, the results of the lesson, students analyzed the impact of this commitment to teaching attitude, it showed a statistically significant positive effect. Fourth, the physical education teacher image showed a positive impact on teaching attitudes through the indirect effect of the path of commitment to teaching statistically significant.
