The Servai Mesh Extender is a low-cost open-source infrastructure-independent telecommunications relay device developed to support telecommunications during and following disasters, as well as in remote and isolated locations. The Mesh Extender has been under development for five years, and is just now transitioning from a primarily University research system, into a mass-producible and deployable...
In this paper, we investigate a tradeoff between the secrecy rate (SR) and energy efficiency (EE) in an underlay cognitive radio network that consists of a cognitive base station (CBS), a cognitive user (CU), a primary user (PU), and multiple eavesdroppers (EDs). By using a so-called secrecy EE (SEE), which is defined as the ratio of SR to the total power consumption of CBS, as the design criterion,...
DPA (Differential Power Analysis) Contest is well-known international framework that allows researchers to compare their power analysis attacks under the same conditions. The latest version of DPA Contest V4.2 provides an improved software implementation of the Rotating Sbox Masking (RSM) scheme. The improved RSM combines low-entropy boolean masking with the shuffling technique to protect AES (Advanced...
Advances in micromachining technology can facilitate the integration of SAW (Surface Acoustic Wave) devices and CMOS circuitry on IC scale substrate for Monolithic fabrication. The optimal design and performance of these filters can be reached by using new Smart materials. The key component in the structure of the SAW device is the piezoelectric materials used which depends mainly on some important...
