Speech and speaker recognition systems are employed in a variety of applications, from
personal assistants to telephony surveillance and biometric authentication. The wide …

Modern electronic devices have become “smart” as well as omnipresent in our day-to-day
lives. From small household devices to large industrial machines, smart devices have …

A smart home personal assistant technology is an intrinsic system, which incorporates many
elements such as users, Smart Home Personal Assistants (SPA) devices, cloud, skill …

Smart Home Personal Assistants (SPA) have a complex ecosystem that enables them to
carry out various tasks on behalf of the user with just voice commands. SPA capabilities are …

We propose a new class of signal injection attacks on microphones by physically converting
light to sound. We show how an attacker can inject arbitrary audio signals to a target …

In this paper, we provide the first large-scale empirical analysis of IoT devices in real-world
homes by leveraging data collected from user-initiated network scans of 83M devices in 16M …

Cyber–physical systems (CPSs) are new types of intelligent systems that integrate
computing, control, and communication technologies, bridging the cyberspace and physical …

Stealing attack against controlled information, along with the increasing number of
information leakage incidents, has become an emerging cyber security threat in recent …

Adversarial attacks against commercial black-box speech platforms, including cloud speech
APIs and voice control devices, have received little attention until recent years. Constructing …

Recently studies show that adversarial examples (AEs) can pose a serious threat to a “white-
box” automatic speech recognition (ASR) system, when its machine-learning model is …
