Designing and Implementing Secure Automotive Network for Autonomous Cars

Abstract

In this paper, a System on Chip (SoC) was designed to prevent external intervention by using Advanced Encryption Standarts (AES) encryption methods for data exchange between between in-vehicle sensors and electronic control units (ECU) of autonomous vehicles. Secure on-board communication (SecOC) with a layered structure in the literature has been chosen to provide secure communication between in-vehicle electronic control units (ECU). The security algorithm of this softwarebased system has been implemented on Field Programmable Gate Arrays (FPGA) with verilog hardware design language (HDL). After the hardware implementation was run, the synthesized block was run with a program written in C using the Microblaze processor that can be implemented on the FPGA. Finally, an application was written in the application layer with the working blocks and tested.
