Robotic Autonomous Vehicles (RAVs) rely on their sensors for perception, and follow strict mission specifications (e.g., altitude, speed, and geofence constraints) for safe and timely operations. Physical attacks can corrupt the RAVs' sensors, resulting ...

The expansion of flip-chip technologies and a lack of backside protection make the integrated circuit (IC) vulnerable to certain classes of physical attacks mounted from the IC's backside. Laser-assisted probing, electromagnetic, and body-biasing ...

Sensors are crucial for perception and autonomous operation in robotic vehicles (RV). Unfortunately, RV sensors can be compromised by physical attacks such as sensor tampering or spoofing. In this paper, we present DeLorean, a unified framework for ...

Recent studies have demonstrated that finely tuned deep neural networks (DNNs) are susceptible to adversarial attacks. Conventional physical attacks employ stickers as perturbations, achieving robust adversarial effects but compromising ...

In view of the invisibility and robustness of the existing physical attacks, the authors propose the adversarial catoptric light, which uses genetic algorithm to optimise the physical parameters of the catoptric light to perform black‐box physical ...

Machine learning (ML) and Deep learning (DL) have been widely studied and adopted for different applications across various fields. There is a growing demand for ML implementations as well as ML accelerators for small devices for Internet-of-...

The concept of moving target defense (MTD) has entrenched itself as a viable strategy to reverse the typical asymmetries in cyber warfare. MTDs are technologies that seek to make target systems dynamically change in order to limit the time and ...

It has been previously shown that hardware implementation of fault attack countermeasures based on error-detecting codes (EDCs) can make the circuit more vulnerable to power analysis attacks. We revisit this finding and show that the hypothesis space ...

As with most aspects of electronic systems and integrated circuits, hardware security has traditionally evolved around the dominant CMOS technology. However, with the rise of various emerging technologies, whose main purpose is to overcome the ...

Fingerprinting of various physical and logical devices has been proposed for uniquely identifying users or devices of mainstream IT systems such as PCs, laptops, and smart phones. However, the application of such techniques in Industrial Control Systems (...

Tamper-proof hardware designs present a great challenge to computer architects. Most existing research limits hardware trusted computing base (TCB) to a CPU chip and anything off the CPU chip is vulnerable to probing and tampering. This paper introduces ...

An attack detection scheme is proposed to detect data integrity attacks on sensors in Cyber-Physical Systems (CPSs). A combined fingerprint for sensor and process noise is created during the normal operation of the system. Under sensor spoofing attack, ...

Secure elements widely used in smartphones, digital consumer electronics, and payment systems are subject to fault attacks. To thwart such attacks, software protections are manually inserted requiring experts and time. The explosion of the Internet of ...

As embedded devices (under the guise of "smart-whatever") rapidly proliferate into many domains, they become attractive targets for malware. Protecting them from software and physical attacks becomes both important and challenging. Remote attestation is ...

We present RamCrypt, a solution that allows unmodified Linux processes to transparently work on encrypted data. RamCrypt can be deployed and enabled on a per-process basis without recompiling user-mode applications. In every enabled process, data is ...

An active shield is a sensor mesh devised and implemented on top of most secure chips or in a secure embedded system as a good protection for circuits and sensitive data stored in the chips. It is one of the most effective annoyances for microprobing ...

Embedded sensing systems are pervasively used in life- and security-critical systems such as those found in airplanes, automobiles, and healthcare. Traditional security mechanisms for these sensors focus on data encryption and other post-processing ...

Recent events demonstrated the vulnerability of power grids to cyber attacks and to physical attacks. Therefore, we focus on joint cyber and physical attacks and develop methods to retrieve the grid state information following such an attack. We ...

As Internet of Things (IoT) evolves very rapidly, security components (cryptographic algorithm, protocol) of embedded devices need to be secure against software and physical attacks. However, the performance factors namely speed, area, and power play a ...

Hardware Trojan Horses (HTH) are a serious threat to semiconductor industry with significant economic impact. However, most of the research in HTH focuses on detection. We propose the concept of "encoded circuit", as a technique to protect HTH ...

In cloud computing, most of the computations and data in the data center do not belong to the cloud provider. This leaves owners of applications and data concerned about cyber and physical attacks which may compromise the confidentiality, integrity or ...
