  • Automated cyber security tester for Smart Devices in industry
    Vysoké učení technické v Brně. Fakulta elektrotechniky a komunikačních technologií, 2020
    Co-Authors: Dávidík Roland
    Abstract:

    This diploma thesis explains the principle of SCADA systems and describes the DLMS/COSEM protocol. In the next part, it shortly describes the Modbus protocol and details the pros and cons of the Modbus protocol in comparison with the DLMS/COSEM protocol. In the next part, an open-source automated scanner was created. This scanner detects Devices in a laboratory network. As the next step, the automated scanner finds out open ports and active services, which run on these Devices, and tries to attack HTTP, SSH, and Telnet services. Next, the program checks, whether the found Device is a Smart-Meter Device and if it is compatible with DLMS/COSEM protocol. If yes, it checks, if the service is vulnerable to DOS attack and breaker disconnection. Scanner’s findings are presented in a newly created web application. NMAP, Masscan, and Metasploit open-source programs are used in the automated scanner. The whole automated scanner is optimized for the HW Device Raspberry Pi with the operating system Raspbian Buster Lite installed. This work also describes the testing of the scanner on the laboratory environment and the results are evaluated afterwards

  • Automated cyber security tester for Smart Devices in industry

    Abstract:

    Táto diplomová práca vysvetluje princíp SCADA systémov a popisuje DLMS/COSEM protokol. Ďalej stručne popisuje Modbus protokol a popisuje výhody a nevýhody protokolu Modbus oproti DLMS/COSEM protokolu. Po popise protokolu je v diplomovej práci vytvoréný open-source automatizovaný skener, ktorý detekuje zariadenia v laboratórnej sieti. Potom automatozovaný skener zistí otvorené porty a aktívne služby, ktoré bežia na týchto zariadeniach, a pokúsi sa zaútočiť na služby HTTP, SSH a Telnet. Potom program overí, či je zariadenie Smart-Meter kompatibilný s DLMS/COSEM protokolom. Ak áno, tak overí, či je zariadenie zraniteľné na útok DOS a na rozpojenie breakeru. Výsledky zistenia programu sú prezentované na vlastnej vytvorenej webovej aplikácii. V automatizovanom skenery sú použité open-source programy NMAP, Masscan a Metasploit. Celý automatizovaný skener je optimalizovaný pre hardwarove zariadenie Raspberry Pi s operačným systémom Raspbian Buster Lite. Ďalej je v diplomovej práci otestovaný tento skener na laboratórnom prostredí a je vyhodnotená správnosť jeho výsledkov.This diploma thesis explains the principle of SCADA systems and describes the DLMS/COSEM protocol.

  • RANCANG BANGUN Smart ENERGY Meter BERBASIS DYNAMIC PRICING
    2019
    Co-Authors: Gerdi Akbar - Illahi
    Abstract:

    Pada penelitian ini dilakukan perancangan dan pembuatan alat pengukuran dan penerapan biaya penggunaan energi dengan aplikasi dynamic pricing menggunakan mikrokontroler. Arduino UNO digunakan sebagai pusat pengolahan data perangkat. Penelitian ini bertujuan untuk merancang sistem pengelolaan sisi beban oleh penyedia energi listrik dengan metode dynamic pricing yang diterapkan pada perangkat Smart Meter. Sistem yang dirancang tersusun atas perangkat Meter pada sisi server, perangkat Meter pada sisi beban, server layanan MQTT dan perangkat telemetri. Penelitian ini dilakukan dengan studi literatur dan datasheet perangkat, lalu dilanjutkan dengan algoritma proses dan alur data serta percobaan penerapannya pada perangkat hingga ditemukan hasil yang memuaskan. Hasil pengujian pada rangkaian perangkat yang dibuat berdasarkan rancangan menunjukan bahwa perangkat berhasil membaca dan mengukur penggunaan beban, menampilkan hasil pembacaan pada perangkat tampilan, memproses dynamic pricing, serta menampilkan hasil pembacaan pada perangkat telemetri dengan rata-rata galat relatif pembacaan yang kecil, yaitu sebesar 4%. ;---In this research, design of a Smart energy Metering Device using dynamic pricing method with a microcontroller is proposed. An Arduino UNO board is used as the system’s main data processing Device. The purpose of this research is to design a demand-side management system which is aplied through the proposed Smart Meter Device. The system is consisted of supply side Meter Device, load side Meter Device, an MQTT server, and telemetry Devices. This research is done through literatural and Devices datasheets study which is then used as the base knowledge for designing the system data flow and algorithm. The system designed is then go through several simulation and actual test repetition until the test resulting a satisfactory output. The said test result showed that the Meter Device is able to read and charge energy usage, display the readings, process the dynamic pricing method, and display reading values through the telemetry Devices with relative error value averaging at 4 %

  • Smart Meter Device for data collection and scada monitoring
    2018
    Co-Authors: Nawawi, Sophan Wahyudi, Mazlan, Ahmad Abid
    Abstract:

    Smart Meter has a lot of benefits to society. By using a digit recognition Device which will read an electric Meter using image processing, the Device can be planted to any existing electric Meter without actually doing an alteration to the existing Meter thus, upgrading the Meter to become a Smart Meter where it can be monitored at any place and any time. Raspberry Pi has been used as the main controller for the Device with a camera and soft wares build and installed along with it. XAMP and RealVNC has been used together to create the IOT part of the Device which connected the Meter to the main computer. This study has conducted the testing of the Device towards a digital voltMeter and images of Meter in the internet

  • Privacy-Preserving Electricity Billing System Using Functional Encryption
    'MDPI AG', 2019
    Co-Authors: Hee-yong Kwon, Seong-yun Jeon, Mun-kyu Lee
    Abstract:

    The development of Smart Meters that can frequently measure and report power consumption has enabledelectricity providers to offer various time-varying rates, including time-of-use and real-time pricing plans. High-resolution power consumption data, however, raise serious privacy concerns because sensitive information regarding an individual’s lifestyle can be revealed by analyzing these data. Although extensive research has been conducted to address these privacy concerns, previous approaches have reduced the quality of measured data. In this paper, we propose a new privacy-preserving electricity billing method that does not sacrifice data quality for privacy. The proposed method is based on the novel use of functional encryption. Experimental results on a prototype system using a real-world Smart Meter Device and data prove the feasibility of the proposed method
