“…Developing methods to combat these new challenges has drawn interest from a number of researchers. This has included classical approaches such as designing hardware security chips for mobile devices [18] and secure firmware validation and update schemes for personal home devices [8]. Other areas of interest include security architecture for edge devices [33] and protecting the runtime data of embedded systems through hardware-enhanced cryptographic engines including AES and the hashing algorithm LHash [35].…”

Within vehicles, the Controller Area Network (CAN) allows efficient communication between the electronic control units (ECUs) responsible for controlling the various subsystems. The CAN protocol was not designed to include much support for secure communication. The fact that so many critical systems can be accessed through an insecure communication network presents a major security concern. Adding security features to CAN is difficult due to the limited resources available to the individual ECUs and the costs that would be associated with adding the necessary hardware to support any additional security operations without overly degrading the performance of standard communication. Replacing the protocol is another option, but it is subject to many of the same problems. The lack of security becomes even more concerning as vehicles continue to adopt smart features. Smart vehicles have a multitude of communication interfaces would an attacker could exploit to gain access to the networks. In this work we propose a security framework that is based on physically unclonable functions (PUFs) and lightweight cryptography (LWC). The framework does not require any modification to the standard CAN protocol while also minimizing the amount of additional message overhead required for its operation. The improvements in our proposed framework results in major reduction in the number of CAN frames that must be sent during operation. For a system with 20 ECUs for example, our proposed framework only requires 6.5% of the number of CAN frames that is required by the existing approach to successfully authenticate every ECU. CCS Concepts: • Security and privacy → Hardware-based security protocols; Embedded systems security; • Computer systems organization → Embedded systems.

Internet of Things (IoT) devices can be considered a significant component within cyber-physical systems. They can provide network communication in addition to controlling the various sensors and actuators that exist within the larger cyber-physical system. IoT devices tend to be small and contain a limited battery supply. They typically have strict constraints placed on their power consumption and available hardware resources. It is for these reasons that energy-efficiency is a major consideration in the design of these resource-constrained devices. In addition, these devices are often deployed in unsecured locations which raises concerns about the security of the device. However, the limited amount of available resources presents an obstacle towards the implementation of security protocols for these cyber-physical systems. Physically Unclonable Functions (PUFs) show promise as a potential security option. PUFs can help provide protection from issues such as IC piracy, counterfeiting, etc. Furthermore, solar cells have been utilized as a power source in IoT devices. In this paper, we propose a novel solar cellbased PUF that leverages the intrinsic variations present in solar cells. As a proof of concept, we have constructed multiple copies our proposed solar cell-based PUF using amorphous silicon, monocrystalline silicon, and polycrystalline solar cells. The reliability and uniformity of the responses produced by the copies of the PUFs made from the different types of solar cells were evaluated against variations in temperature and light intensity. From our experiments, we found that with respect to temperature the range of average reliability values was 84.41-91.20% and the range of average uniformity values was 49.34-51.26%. With respect to light intensity, the range of average reliability values was 95.45-97.75% and the range of average uniformity values was 48.74-52.81%. In addition, Monte Carlo simulations performed on monocrystalline silicon resulted in a uniqueness value of 49.989%.
