We present a novel way to detect infected hosts and identify malware in networks by analyzing network communication statistics with state-of-the-art automata learning algorithms. The automata encode patterns of short-term interactions in known malicious hosts, and are used to obtain small but effective fingerprints of machine behavior. We showcase the effectiveness of our system, named BASTA1 (Behavioral...
Radio Frequency IDentification (RFID) plays a vital role in smart computing applications. Due to the limited communication range of individual RFID readers, large RFID systems deployed in real applications usually contain multiple readers. Existing reader scheduling algorithms either disallow adjacent readers to simultaneously work in order to avoid collisions among them, or simply activate all the...
IoT (Internet of Things) is a network of interconnected devices, designed to collect and exchange data which can then turn it into information, eventually into wisdom. IoT is a region where digital world converges with physical world. With the evolution of IoT, it is expected to create substantial impact on human lives. IoT ecosystem produces and exchanges sizeable data due to which IoT becomes an...
The next industrial revolution, generally referred to as Industry 4.0, is already here. This envisions a rapid transformation in the design, operation and service of manufacturing systems, where machines, sensors and actuators are interconnected in the factories in order to enable spontaneous collaboration, monitoring and control. Currently, Cyber-Physical-Systems (CPS) use regular Internet protocols...
In the era of Internet of Things (IoT), we face the challenges of integrating new IoT systems with the existing systems, which are in services for large scale and economic implementations. In this paper, we explore an approach for integrate wired-wireless systems based on industrial standards, such as Zigbee and DALI for optimizing the energy use as well as timely communicating the vital signals to...
One of the challenging characteristics of Fog and Mobile Edge Computing (FMEC) is the trustworthiness among the wireless sensor nodes. In FMEC, sensors participate in data analytics by collaborating with each other. Sensors are communicating as far as they are paired each other or the radio pipe addresses are matched. Once paired, microcontrollers units (MCUs) are allowed to transmit sensor data to...
This paper studies an observer that seeks to predict in minimal time the asymptotic agreement value of the agents in a network. The network is governed by the DeGroot opinion dynamics model. The observer can monitor the opinions of a group of agents, but might not have accurate knowledge of the underlying communication graph and the associated weight matrix. The work makes use of and builds on previous...
This paper introduces an extendable and generic base architecture built on Universal Verification Methodology (UVM) for verifying Flash memory controller designs. The base architecture aims to create a generic and configurable abstraction verification environment for Flash memory controller designs. It integrates the essential UVM Verification Components (VCs), defines the functionalities of the VCs,...
Distribution grid dynamics are becoming increasingly complex due to the transition of these networks from passive to active networks. This transition requires increasing the observability and awareness of the interactions between Transmission and Distribution (T&D) grids, particularly to guarantee adequate operational security. As part of the work carried out in the EU-funded IDE4L project, a...
Maintaining a coordinated power distribution network with multiple power sources and numerous network power connections can be very challenging. For some systems, these various combinations for loads and sources that allow power to flow through a customer's distribution grid can also create unsafe conditions for the distribution equipment as well as the operators who work in close proximity to the...
Situational awareness during sophisticated cyber attacks on the power grid is critical for the system operator to perform suitable attack response and recovery functions to ensure grid reliability. The overall theme of this paper is to identify existing practical issues and challenges that utilities face while monitoring substations, and to suggest potential approaches to enhance the situational awareness...
WSN(Wireless Sensor Network) is an application specific network. There is no general optimized solution for WSN problems. It depends upon application, resource availability. Structural health monitoring (SHM) using wireless sensor networks has drawn considerable attention in recent years. It is an active area of research that can autonomously and proactively assess the structural integrity of buildings,...
The use of Wireless sensor network is to monitor an area for event detection. The sensor node have some limitation like the sensor node associated with battery power and generally it is not possible to recharge or replace battery of sensor due to large number of sensor node, node distribution in remote, desert or hostile areas etc. The energy consumption of sensor node appears a lot of challenges...
Software Defined Network (SDN) is a proposal to networking world for global administration and management of network services. It also provides an abstraction of networking elements. Most of the security innovations in SDN are bound to an OpenFlow security framework which creates and implement security policies while detecting malicious traffic, that too in a flexible way. Existing methodologies convert...
A Matlab Graphical User Interface (GUI) to help monitor the human gait in real time, and to enable to better understand the information of the used Inertial Measurement Units (IMUs) system is here presented. The interface not only improved the speed of data processing, but also facilitated the interaction between the user and the system, providing a clearer change of variables and information exchange...
The development of remote control technology has grown rapidly along with the development of communication technology nowadays. The simplest communication technology available is by using GSM protocol. In this paper, a prototype of electric appliance control tool via SMS by using GSM is proposed. GSM protocol was chosen because it does not depend on mobile devices' platform. GSM SIM 900 and Arduino...
Traffic monitoring and analysis has become necessary to understand the nature of information flowing within an organization. This is particularly important due to the recent trend of increase in the percentage of anomalous traffic in the overall organizational traffic composition. In this work, we attempt to determine the typical characteristics seen in various organizational network traffic. We use...
The emergence of the smart grid has led to the development of a diverse set of standards and protocols for achieving interoperability among smart devices. These smart grid related standards and protocols cover a wide variety of power system components and functionalities. In this paper, a comprehensive review of commonly used standards and protocols in the smart grid environment is provided, ranging...
In many modern applications, input data is represented as matrices and often arrives continuously. The ability to summarize and approximate data matrices in streaming fashion has become a common requirement in many emerging environments. In these applications, input data is usually generated at multiple distributed sites and simply centralizing all data is often infeasible. Therefore, novel algorithmic...
Technological advancement of Industrial Control Systems (ICS) and control systems automation over the past decade has brought greater interconnections of the control components.
