In secure two-party computation protocols based on garbled circuit, oblivious transfer (OT) plays an important role in transferring the garbled keys of the participants. In addition to the traditional OT primitive, many other variants of OT have also been presented, such as outsourced oblivious transfer (OOT), cut-and-choose oblivious transfer (CCOT), cut-and-choose bilateral oblivious transfer (CCBOT),...
Proxy signature scheme enables a signer to delegate its signing rights to any other user, called the proxy signer, to produce a signature on its behalf. In a proxy multi-signature scheme, the proxy signer can produce one single signature on behalf of multiple original signers. We propose an efficient and provably secure threshold-anonymous identity-based proxy multi-signature (IBPMS) scheme which...
In the future, state-of-the-art wind generators (WGs) are expected to produce one of the largest amounts of renewable energy worldwide. Nowadays, wind DFIGs with integrated storage are regarded as the state-of-the-art WGs. In this paper, we propose a comprehensive methodology that aims to solve the problem of distributed coordination and control of state-of-the-art WGs. The goal is for a WF to generate...
In this paper we propose a method for dispatching a fleet of wind doubly-fed induction generators (DFIGs) in a fair fashion according to a prespecified total power reference. In our context fair means that wind generators (WGs) are required to reach the same utilization levels after dispatched. We pose the problem as a constrained consensus problem on the utilization levels among the rotor-side converters...
In order to achieve optimal operation conditions in a microgrid with Energy Management System (EMS), a communication system is needed. It is important to consider in depth different characteristics of communication systems regarding issues like determinism, time constrains, cost effectiveness etc. This paper reviews different type of network protocols which can be used in order to fulfill the different...
Today, the main challenges in front of suppliers of networking hardware and software are to test their product under heavy traffic load. Such investigation is usually carried out in the laboratory where the prodigious amount of traffic is required. So one question emerges here is that from where to bring this tremendous traffic. Networking research community suggests a synthetic traffic generator...
The paper presents a prototype of a microsystem for the integration and the optimal management of renewable energy sources in order to attain a reduction of the total energy consumption of a not residential building. The system composed by the building and the prototype is an energy sustainable microsystem and is located in Italy in the city of Valderice. The microsystem has been conceived in the...
The continuity of electrical energy is the main subject among all others affecting operational sustainability in industrial facilities. Therefore electrical system and its extensions shall be controlled, supervised, monitored and protected by intelligent systems. Hence, it is necessary to incorporate into electrical system required resources and hardware that will enhance the safety and sustainability...
As the complexity of design of chip is increased in last decade, designers were not able to manage to design and verify the functionality of design. So the verification of chip as a separate field progressed in the last decade. In this project intention is to verify functionality of PCI (Peripheral Component Interconnect) target and Wishbone master interface module as per the specifications of PCI...
Hiding memory access patterns is required for secure computation, but remains prohibitively expensive for many interesting applications. Prior work has either developed custom algorithms that minimize the need for data-dependant memory access, or proposed the use of Oblivious RAM (ORAM) to provide a general-purpose solution. However, most ORAMs are designed for client-server scenarios, and provide...
Software Defined Networking and OpenFlow offer an elegant way to decouple network control plane from data plane. This decoupling has led to great innovation in the control plane, yet the data plane changes come at much slower pace, mainly due to the hard-wired implementation of network switches. The P4 language aims to overcome this obstacle by providing a description of a customized packet processing...
For the last decades, the advancement of system on chips complexity and size are driving the verification process of the digital designs to be much more complicated and time consuming. Moreover, nowadays, the verification process takes up to 80% of overall design development time. This paper emphasizes the importance of automatic testbench generator for industrial wireless local area network (iWLAN)...
Delay Tolerant Networks (DTN) with store and forward architecture are able to operate in environment with considerable delays and intermittent connectivity. Evaluation of such networks and protocols requires reliable simulation tool as is OPNET (Optimized Network Engineering Tool) modeler. One drawback of the OPNET is missing implementation of the wireless DTN protocols and models, therefore we developed...
A Community Network (CN) is a bottom-up network infrastructure that interconnects communities of people and represents a promising and successful networking model. The more people join a CN, the higher is the demand for a wider range of community services and the need for scalable network protocols. CN designers and passionates hence require adequate frameworks to develop and test different technical...
Software Defined Networking (SDN) is the potential future backbone of all computer networking. The main advantage of SDN is that it separates the control plane from the data plane. This delegates switching/routing decisions to a controller that is connected to the switches. The connectivity of the switches and controllers can be represented as a network topology. Usually a network topology has to...
The aim of this paper is to understand the dynamics and tools required to develop a software-based L4–L7 traffic generator. The main goal of this paper is to provide a simple, efficient and complete framework for fast packet processing in data plane applications. Conventional techniques of packet processing are rather slow, time-consuming and inefficient. Fast packet processing on the other hand,...
Micro-grids allow rural and remote communitiesthat are either not connected to the national power grid, or sufferfrom load shedding, to operate power networks autonomously. Like conventional power networks, micro-grids require management and billing mechanisms. Tamper-resistant meters are noteconomically viable so we use a resource-constrained networkformed of devices with limited memory, processing...
Recent developments in secure computation have led to significant improvementsin efficiency and functionality. These efforts created compilers that form thebackbone of practical secure computation research. Unfortunately, many of theartifacts that are being used to demonstrate new research for secure computationare incomplete, incorrect, or unstable, leading to demonstrably erroneousresults and inefficiencies...
Reproducing complex networks with features of real-life networks is exciting and challenging at the same time. Based on the popular Omnet++ discrete event simulator, we introduce Armonia, a framework for modeling massive networks and their dynamic interactions. It includes a collection of topology generators, a set of resource placement and replication modules, a component for specifying resource...
