Power analysis on smart cards is widely used to obtain information about implemented cryptographic algorithms. We propose similar methodology for Java Card applets reverse engineering. Because power analysis alone does not provide enough information, we refine our methodology by involving additional information sources. Issues like distinguishing between bytecodes performing similar tasks and r...

The critical infrastructure powering the nation is currently undergoing a massive collaborative effort to integrate modern technologies with 50 year-old assets derived from 100 year-old designs. Improving the existing electric power infrastructure with smart grid technologies compounds existing threats with new threats. Identification of next generation smart grid security threats is vital for ...

Data communications infrastructure plays an importantrole to communicate information (e.g., related to powergeneration, supply, consumption) among the variouselements in the smart grid. In this letter, excerpted from[1], we consider the reliability of the smart grid datacommunications infrastructure and its impact on theoptimization of power consumption in the smart ...

Power systems are underlying inevitable changes. Their transition phase from traditional into smart power systems is analysed by means of the three main components: power plants, grid and consumers; their management systems and the operators’ role. Results show that power systems are undergoing a spiral evolution process with revolutionary elements only in the first transition phase of the inte...

The Smart Grid concept introduces an updated architecture and new elements to the traditional power grid. As a result, existing survivability schemes that have been designed with a centralized architecture in mind are either inefficient or no longer applicable. In this paper, we review several solutions that have been suggested in the literature in order to ensure the proper operation of the po...

The future smart grid is envisioned as a network of interconnected microgrids (MGs) – small-scale local power networks comprising generators, storage capacities and loads. MGs bring unprecedented modularity, efficiency, sustainability, and resilience to the power grid as a whole. Due to the high share of renewable generation, MGs require innovative concepts for control and optimization, giving ...

this paper presents a probabilistic optimal power flow (popf) algorithm considering different uncertainties in a smart grid. different uncertainties such as variation of nodal load, change in system configuration, measuring errors, forecasting errors, and etc. can be considered in the proposed algorithm. by increasing the penetration of the renewable energies in power systems, it is more essent...

The ever-increasing computational power of smart cards has made them feasible for applications like electronic passports and military id cards. However, these applications require a secure smart card operating system. In this paper we argue that smart card platforms pose additional security challenges than traditional computer platforms. We discuss our design for a secure smart card operating s...

Intelligent power grid research, i.e. smart grid, involves many simultaneous users spread over a relatively large geographical area. A tool for advancing research and community education is presented utilizing large-scale visualization centers, e.g. planetariums, in simulating smart grid interactions. This approach immerses the user in virtual smart grid visualization and allows the user, with ...

Smart Grid facilitates real-time communication network between the user and the grid company by smart terminals, which utilizes bidirectional data transmission and information control. In Smart Grid, the smart meters play important role by measuring the amount of electricity consumption and sending various information to the power generators and substations.
