Abstract
Smart meters are of the basic elements in the so-called Smart Grid. These devices, connected to the Internet, keep bidirectional communication with other devices in the Smart Grid structure to allow remote readings and maintenance. As any other device connected to a network, smart meters become vulnerable to attacks with different purposes, like stealing data or altering readings. Nowadays, it is becoming more and more popular to buy and plug-and-play smart meters, additionally to those installed by the energy providers, to directly monitor the energy consumption at home. This option inherently entails security risks that are under the responsibility of householders. In this paper, we focus on an open solution based on Smartpi 2.0 devices with two purposes. On the one hand, we propose a network configuration and different data flows to exchange data (energy readings) in the home. These flows are designed to support collaborative among the devices in order to prevent external attacks and attempts of corrupting the data. On the other hand, we check the vulnerability by performing two kind of attacks (denial of service and stealing and changing data by using a malware). We conclude that, as expected, these devices are vulnerable to these attacks, but we provide mechanisms to detect both of them and to solve, by applying cooperation techniques.
Highlights
The interconnection of devices in electricity networks to support the exchange of data has become an essential aspect that electricity companies need to face
We firstly describe the devices we have used for our proof of concept and the different data flows designed to support the exchange of energy readings within the domestic network and to prevent integrity attacks
Smart meters are one of the most basic elements in the Smart Grid, but they are essential for this new infrastructure
Summary
The interconnection of devices in electricity networks to support the exchange of data has become an essential aspect that electricity companies need to face. Plan stage establishes a series of actions required to deliver the desired results; the do stage allows the decisions taken in the previous step to be implemented, sometimes pilot testing are used to verify their effects; in the check stage, the results of the implementation are monitored and compared with the initial objectives to see to which extent they have been attained; in the act stage results and the objectives are analyzed, suggestions are gathered and issues are detected in order to improve the process Within this scenario, some approaches have arisen with the aim of providing mechanisms able to support a more secure context for the Smart Grid and to prevent unauthorized access to this sensitive information.
