Privacy Model for Smart Meter in Multi-Hop Network Environment

Abstract

The transition from traditional power grids to smart grids represents a significant shift in the way we manage and utilize electrical power. This evolution brings about numerous opportunities and challenges in power system operations. The increased granularity of energy consumption data in smart grids can indeed raise privacy concerns. The smart meter data or high-resolution energy data, provides insight into specific patterns of energy use within a household. These patterns can be analyzed to infer various aspects of a consumer’s behavior and lifestyle. The present title discloses the anti-theft model for multi hop smart grid node using embedded system. In the designed system, sensors are used to read the values of current and voltage. These values of voltage and current are converted into watt per minute. The standard AES 128 encryption technique is engaged to perform encryption. For encryption of the readings, “IV Key” and “ENC Keys” are used and the encrypted values are uploaded on to the Fire Base Server. The replica of the keys is updated on to another ESP processor. To access the real values of the node, android application is designed through which user have to enter the correct values of the private key. Once the key is entered through the android application, through the FIRE Base Server, the keys are sent to the ESP node for verification, if the true key is entered, the decrypted values are displayed on the android application and if wrong key is entered then random values are displayed. The system is also implemented with RSA(Rivest-Shamir-Adleman) algorithm on ESP32 Arduino platform. Later the results of both the methods are compared to gain better results. Making use of simple processes and procedures, the proposed model is made suitable for devices with minimal computational resources.
