The software-based implementation of differential privacy mechanisms has been shown to be neither friendly for lightweight devices nor secure against side-channel attacks. In this work, we aim to develop a hardware-based technique to achieve differential ...

Two-factor authentication key exchange (AKE) is an effective way to strengthen the security of password-authenticated key exchange. Most two-factor AKE schemes using smart cards as the second factor require users to have the second factor with them any ...

A voiceprint is the distinctive pattern of human voices widely used for authentication in voice assistants. This article investigates the impact of speech contents and speech rates on the distinctiveness of voiceprint, and has obtained answers to three ...

Generative steganography has become a popular research topic in the field of generative AI, including generative image and synthetic speech steganography. However, music files have different statistical properties and knowledge representation compared to ...

Countermeasures and deterrents to power side-channel attacks targeting the alteration or scrambling of the power delivery network have been shown to be effective against local attacks where the malicious agent has physical access to the target system. ...

Byzantine Fault Tolerance (BFT) Consensus protocols with trusted hardware assistance have been extensively explored for their improved resilience to tolerate more faulty processes. Nonetheless, the potential of trust hardware has been scarcely ...

Voice assistants are widely integrated into a variety of mobile devices, enabling users to easily complete daily tasks and even critical operations like online transactions with voice commands. Thus, once attackers replay a secretly-recorded voice command ...

Cache side-channel attacks remain a stubborn source of cross-core secret leakage. Such attacks exploit the timing difference between cache hits and misses. Most defenses thus choose to prevent cache evictions. Given that two possible types of evictions&#...

Voice assistants, increasingly integrated into wearable devices with limited human-computer interaction modalities, are susceptible to voice spoofing attacks. Such attacks exploit pre-recorded or synthesized voice commands to trick the assistants into ...

A recent trend in binary code analysis promotes the use of neural solutions based on instruction embedding models. An instruction embedding model is a neural network that transforms assembly instructions into embedding vectors. If the embedding network is ...

As the scale of high-performance computing systems (HPC) continues to expand, the frequency of failures within the system also increases. The follow-up steps in the event of a failure are necessary because efficient prevention measures are absent. These ...

Smart tags are compact electronic devices affixed to or embedded into objects to facilitate identification, monitoring, and data exchange. Consequently, secure authentication of these tags is a crucial issue, as objects must reliably verify their identity ...

Cooperative jamming (CJ) is a promising technique for enhancing the physical-layer security in wireless powered sensor networks. The secrecy performance of CJ-aided wireless powered sensor networks is affected by three issues including disguised ...

Transient faults or soft errors are considered one of the most daunting reliability challenges for microprocessors. Software solutions for soft error protection are attractive because they can provide flexible and effective error protection. For instance, ...

This article proposes a tag-based approach for physical (PHY)-layer authentication in a reconfigurable intelligent surface (RIS) communication system. We first extract the intrinsic PHY-layer features of RIS communication systems in terms of channel gain ...

This study explores data-driven detection of firmware/software Trojans in embedded systems <italic>without</italic> golden models. We consider embedded systems such as single board computers and industrial controllers. While prior literature considers ...

As a widely used industrial field bus, the controller area network (CAN) lacks security mechanisms (e.g., encryption and authentication) and is vulnerable to security attacks (e.g., masquerade). A fingerprint-based intrusion detection system (IDS) in CAN ...

Building hardware security primitives with on-device memory fingerprints is a compelling proposition given the ubiquity of memory in electronic devices, especially for low-end Internet of Things devices for which cryptographic modules are often ...

System reliability has become a first-class design constraint. As the use of Graphics Processing Units (GPU) continues to increase in compute applications, including High Performance Computing (HPC) and safety-critical applications, so do the number of ...

There has recently been a significant growth in resource-constrained devices (RCDs) that exchange sensitive and private data. Lightweight ciphers are designed to implement confidentiality in RCDs. Hardware implementation of lightweight cipher should ...
