ÐThis paper examines how monitoring power consumption signals might breach smart-card security. Both simple power analysis and differential power analysis attacks are investigated. The theory behind these attacks is reviewed. Then, we concentrate on showing how power analysis theory can be applied to attack an actual smart card. We examine the noise characteristics of the power signals and deve...

The paper proposes a concept of power-consumption optimization in smart homes based on demandside management (DSM) and using smart able to control home electrical devices by a wireless connection. The advantages of the concept are lower power consumption without reducing the users living comfort and enabling the users to actively participate in the smart-grid load shedding.

For century, there has been no change in the fundamental structure of the electrical power grid and vehicle networks. Current hierarchical, centrally controlled grid of the electrical grid is not best for growing demand. To address the challenges of the existing power grid, the new concept of smart grid and smarter planet are under research. The smart grid can be considered as a modern electric...

Smart grid allows the integration of distributed renewable energy resources into the conventional electricity distribution power grid such that the goals of reduction in power cost and in environment pollution can be met through an intelligent and efficient matching between power generators and power loads. Currently, this rapidly developing infrastructure is not as "smart" as it should be beca...

Smart microgrids offer a new challenging domain for power theories and compensation techniques, because they include a variety of intermittent power sources, which can have dynamic impact on power flow, voltage regulation, and distribution losses. When operating in the islanded mode, low-voltage smart microgrids can also exhibit considerable variation of amplitude and frequency of the voltage s...

This paper gives an overview of the smart grids developments, seen from a power-quality viewpoint; describes the main relations between smart grids and power quality, and goes into some detail for some of the aspects. Different types of real and virtual energy storage are distinguished. Power-quality monitoring in the smart grid is discussed in detail. Further aspects discussed in the paper are...

Faculty of Electrical Engineering, Mathematics and Computer Science CE-MS-2006-05 Power analysis of smart cards is commonly used to obtain information about implemented cryptographic algorithms. We propose a similar methodology for reverse engineering of Java Card applets. In order to acquire power traces, we present a new microcontroller based smart card reader with an accurate adjustable trig...

Currently, when Electric Vehicles (EVs) are charging, they only have the option to charge at a selected current or not charge. When during the day there is a power shortage, the charging infrastructure should have the options to either shut off the power to the charging stations or to lower the power to the EVs in order to satisfy the needs of the grid. There is a need for technology that contr...
