“…Furthermore, with the integration of hardware-based obfuscation methods, reverse engineering attacks aimed at extracting keys can be mitigated. The proposed method eliminates the need to store secret keys on non-volatile memory within the nodes or the ECUs, eradicating probing attacks as well [1].…”

“…Two different varieties of PUFs, namely Weak and Strong, exist. A prominent difference lies in the fact that the weak PUF operates with only a limited number of challenges, generating a unique key for each challenge, while the strong PUF has a large challenge space, resulting in a unique response for the majority of applicable challenges [1].…”

“…Once a set of 4096 PNs is collected, a series of operations, executed in VHDL, are initiated to produce a bitstring and helper data. The resulting cryptographic quality of the HELP PUF establishes a reliable, unique, and unpredictable response, forming a robust foundation for applications such as the Public/Private Key Generation Block in cryptographic systems [1].…”

The rapid advancement of technology, alongside state-of-the-art techniques is at an all-time high. However, this unprecedented growth of technological prowess also brings forth potential threats, as oftentimes the security encompassing these technologies is imperfect. Particularly within the automobile industry, the recent strides in technology have brought about increased complexity. A notable flaw lies in the CAN-FD protocol, which lacks robust security measures, making it vulnerable to data theft, injection, replay, and flood data attacks. With the rising complexity of in-vehicular networks and the widespread adoption of CAN-FD, the imperative to safeguard the protocol has never been more crucial. This paper aims to provide a comprehensive review of the existing in-vehicle communication protocol, CAN-FD. It explores existing security approaches designed to fortify CAN-FD, demonstrating multiple multi-layer solutions that leverage modern techniques including Physical Unclonable Function (PUF), Elliptical Curve Cryptography (ECC), Ethereum Blockchain, and Smart contracts. The paper highlights existing multi-layer security measures that offer minimal overhead, optimal performance, and robust security. Moreover, it identifies areas where these security measures fall short and discusses ongoing research along with suggestions for implementing software and hardware-level modifications. These proposed changes aim to streamline complexity, reduce overhead while ensuring forward compatibility. In essence, the methods outlined in this study are poised to excel in real-world applications, offering robust protection for the evolving landscape of in-vehicular communication systems.
