Abstract Details

2018, MS, University of Cincinnati, Engineering and Applied Science: Electrical Engineering.
Modern automobiles are heavily integrated with various embedded devices for wide range of applications. This necessitates a secure and reliable communication network among these embedded devices. CAN bus is currently being used in most automobiles over the past two decades. However, several researchers have demonstrated that compromising the security of the automobile system is feasible by utilizing the vulnerabilities in the embedded device firmware and integration code and then advancing these errors to part or whole of the system through the CAN bus. The limitations of CAN bus arise due to inability to accommodate the recent advancements in cryptography and cyber security solutions because CAN bus was developed before the cyber revolution became widespread. Several researchers have proposed various solutions to address the security issues of the CAN bus. The two main approaches are either to implement signal analysis to identity the faulty messages or to develop an advanced CAN bus to accommodate the emerging cyber security algorithms. However, these solutions are either hardware intensive and cause time delays or are not compatible with the already existing automobile CAN bus systems. Our work proposes a hierarchical partitioning and encapsulation based model system that provides a security layer above the CAN interface. The proposed model allows for early detection of malicious messages and unauthenticated accesses. The approach does not demand complex hardware requirement. As the model accommodates the existing CAN network and does not require hardware changes, it is backwards compatible to the present automobile systems already being used. It is a cost effective and customizable way to accommodate additional user requirements within the pre-set security framework.
