Gatekeeper Modules

Prerequisite

• Ubuntu 18.04
• Linux kernel 5.4.0
• Linux kernel header files: sudo apt install linux-headers-$(uname -r)
• Install wolfSSL 4.8.1 (commit e5caf5 recommended)
• CMake (> 3.10)

Get Started

Here is a brief introduction of all targets:

• kernel_modules: mainly for the authenticator (i.e., targets with the prefix of mitm_auth)
• common: common libraries for Gatekeeper sender/receiver
• can_udp_raw, lidar_udp_raw: replay CAN/LiDAR data over UDP via raw socket, acting as Gatekeeper sender/receiver
• can_udp, lidar_udp: replay CAN/LiDAR data over UDP (can be used with mitm_snd/mitm_recv, deprecated now)
• tesla: TESLA protocol library
• tesla_can_udp, tesla_lidar_udp: replay CAN/LiDAR data over UDP, using TESLA protocol
• benchmark: benchmark applications the time-lock puzzle
• tests: unit tests

Using CMake to build

mkdir build
cd build
cmake ..
make
cp can_udp/udp_client can_udp/udp_server \
    can_udp_raw/udp_client_raw can_udp_raw/udp_server_raw \
    tesla_can_udp/tesla_udp_client tesla_can_udp/tesla_udp_server \
    lidar_udp_raw/lidar_udp_client_raw lidar_udp_raw/lidar_udp_server_raw \
    tesla_lidar_udp/tesla_lidar_udp_client tesla_lidar_udp/tesla_lidar_udp_server \
    tesla/libtesla.so \
    </path/to/SecEthernetEval>

NOTE: SecEthernetEval

Using Makefile for Kernel Modules

cd kernel_modules
# MITM_ROLE=2, for the authenticator
make MITM_ROLE=2
# Can specify other versions of Linux kernel header files
make LINUX_DIR=</path/to/header/files> MITM_ROLE=2
