A secure communication framework for ECUs

Abstract

Electronic Control Units (ECUs) generate diagnostic and telemetric data that is communicated over the internal vehicular network. ECUs are resource constraint devices and have limited resources to devote for data security. In recent times, threats against vehicular networks have emerged that require attention of the research community. In this paper, we demonstrate data security threats in automobile, present a hardware based security framework that provides real time secure communication using lightweight cryptographic primitives and propose hardware based authentication protocol. Implementation details, performance and security analysis of proposed framework are presented.
