Underwater acoustic networked systems often consist of geographically distributed antenna elements (DAEs) that are connected via cables or high-rate radio links (e.g., bottom-anchored nodes or surface buoys). This paper investigates countermeasures against eavesdropping attack in the coordinated multipoint (CoMP) transmission of DAEs to an underwater legitimate user. Exploiting the low sound speed...
Although considerable advances in underwater acoustic (UWA) communications and networking have been made in the last decade, research on the secure UWA communications and networking is limited. In this work, we consider the underwater distributed antenna systems (DAS) consisting of geographically distributed antenna elements (DAEs) that are connected via fibers or high-speed radio links, and address...
We developed an architecture that automatically searches for and downloads Android applications from the Android Market. Furthermore, we created a detailed mapping of Android application programming interface (API) calls to the required permission(s), if any, for each call. We then performed an analysis of 141,372 Android applications to determine if they have the appropriate set of permissions based...
In this paper, we present the design, implementation, and software testing of USBSec, a secure extension of the vanilla USB protocol that incorporates host authentication to defend against software threats. Specifically, we force the USB host to supply authentication information to the peripheral device \emph{before} enumerating the device. The peripheral validates the authentication information against...
