New Episode of The Cyber Show: #050 | S6 | In The Chair | Hardware Security with Dr. Basel Halak
In this episode of The Cyber Show, we are pleased to welcome Dr. Basel Halak, a hardware security expert from the University of Southampton. Dr. Halak shares his research and perspectives on the security of electronic systems, focusing on design techniques to protect against side-channel attacks and energy-efficient protocols. He also explores the integration of machine learning into hardware countermeasures and the security of machine learning algorithms.
Dr. Halak explains that hardware security aims to protect hardware devices, such as smartphones, televisions, and smart sensors, from hardware and software-level attacks. He divides the field into three main themes: the security of the hardware itself, the security of the architecture, and security against physical attacks. He emphasizes the importance of securing basic components, such as CMOS circuits and transistors, as well as trusted architectures like secure elements and ARM TrustZones.
One of the major challenges of hardware security is the increasing complexity of electronic systems and the globalization of the supply chain. This introduces many potentially untrustworthy actors who can tamper with circuits to create backdoors. Dr. Halak compares this challenge to that of software security, noting that while hardware attacks are more difficult to carry out, they can have enormous consequences, such as the Spectre and Meltdown vulnerabilities that affected millions of devices.
The podcast also addresses the implications of intellectual property and the need for verification mechanisms to ensure the security of hardware components. Dr. Halak discusses hardware defense techniques, such as the use of physically unclonable functions (PUFs) and blockchain technology to track components throughout their lifecycle. He warns of the potential risks of these technologies, including the possibility for manufacturers to remotely control devices, which could have dystopian implications.
The conversation then turns to the threats posed by counterfeit components and Trojan attacks on printed circuit boards (PCBs). Dr. Halak explains how signal processing and imaging techniques can be used to detect counterfeit components. He also mentions tools developed to recognize defects left by component reconditioning processes.
Finally, the podcast discusses the practical implications of hardware security for consumers. Dr. Halak advises buying devices from trusted suppliers and being cautious of offers that are too good to be true. He emphasizes the importance of public awareness of the risks associated with smart devices and social media applications like TikTok, which can collect sensitive data.
