ECU To ECU Communication in Automotive Grade Processors and Security of Messages Exchanged

Abstract

An Electronic control unit (ECU) is small microprocessors in a vehicle's body which plays a major role in controlling a specific function.
Vehicles recently may contain 80-100 ECUs or more, managing different functions in the vehicle like security and giving access to Passive safety measures such as airbags, as well as active safety features such as autonomous emergency braking, are all available. The various problems encountered by ECUs are because of loss of communication, incorrect protocol, memory checksum error and also by cause of illegal hacking. In this project inter and intra communication of vehicle is secured thorough encryption and decryption measure. Electronic Control Units (ECUs) create specific and telemetric data that is transferred across the vehicle's internal network. ECUs are low-resource devices with little resources to dedicate to data security. Threats to vehicle networks have recently surfaced, requiring the attention of the scientific community. We propose in this work to employ message transposition and then encrypt the transposed messages, which will assist to improve message security.
