This document summarizes a seminar presentation on the role of cyber security in connected cars. It begins with an introduction on how digital technologies have enabled the development of smarter, safer, and more efficient vehicles. However, as vehicles become more connected through technologies like V2V and V2X communication, they are also more vulnerable to hackers. The document then discusses how modern smart cars can be hacked either physically through ports or remotely through wireless access. It provides examples of potential attack vectors and proposes a multi-layered security architecture with measures like secure onboard communication, software updates, and hardware-based cryptography to secure the vehicle network and ensure safety-critical functions are not compromised.

2. INTRODUCTION
Department of Electrical and Electronics Engineering
 The influx of digital transformation and advancements
the automakers to develop cars that are cleaner, safer,
smarter and more energy-efficient.
 Employ with a series of intelligent technologies such as
Adaptive headlights, Lane keep assist, Collision warning,
Adaptive cruise control, Reversing camera, Hill assist,
Crash-imminent braking.
 Connected cars
 Safer, energy efficient

3. Modern smart cars
 They can have about 70-100 embedded
microcontrollers onboard running millions of lines of
code within them.
 These ECU’s control almost every function of the car
including safety-critical vehicle applications such as
braking, engine control, steering, airbag functions,
navigation systems etc.
 Connected with V2V and infr(V2X )
 They become more vulnerable than ever to attackers
and hackers.
 A compromised infotainment system can offer an
effective vector for attacking safety critical ECU’s
connected to the
In-vehicle network.
 Once a hacker gains access to the in-vehicle network of
the car, they could control everything.

4. Security Attacks Overview
o Active attacks
o Passive attacks
How A Connected Car Can Be Hacked?
 A modern automotive can be hacked either by
physical access or by remote access of the In-Vehicle-Network.
 Direct physical access to the car internal network is possible via OBD port, Debug
ports or Digital multimedia ports.
 Remote access to car is possible via a broad range of attack vectors such as
CD/DVD players, Short-range wireless access – Bluetooth, RFID(remote Keyless
entry, vehicle immobilizers, Tire Pressure Monitoring System), Dedicated Short-
Range Communications and Long-range wireless access – WiFi, Cellular
Technologies(LTE, GSM, CDMA)

6. PROPOSED SYSTEM
Department of Electrical and Electronics Engineering
Securing a Connected
Vehicle
 The security system inside
autonomous connected vehicle
shall ensure that technology in
the connected Car works 100%
of the time without compromising
the safety-critical functions. To
achieve this a multi-layered,
distributed security architecture
with a defense-in-depth strategy
is needed.

8. Security measures to secure vehicle network:
Off Board Network Security
•V2X Security
•Secure external interfaces
•Remote Diagnostics
•Target Authentication
•Secure Software Updates Over the Air(SOTA)
In-Vehicle Network Security
•Secure Boot
•Secure Flashing
•Secure Access
•Secure Storage
•Secure Onboard Communication(SecOC)
•Secure Diagnostics
•Key Management
•Auditing and Logging
•Hardware based Crypto(HSM/SHE)
•Machine Security & Tamper protection
