DLMS/COSEM protocol security
Tomko, Tomáš ; Mlýnek, Petr (referee) ; Lieskovan, Tomáš (advisor)
The aim of this thesis is to familiarize the reader with the DLMS/COSEM protocol, which is mainly used in the power industry. The thesis introduces the concept of smart grids along with their development and basic legislation. In the following section, all the protocols used in smart energy networks are discussed with most emphasis on the mentioned DLMS/COSEM protocol and its security features and vulnerabilities. Furthermore, the thesis aims to introduce the reader to the security risks in industrial networks and the Cyber Range KYPO platform. It was important to familiarize with the capabilities that this platform offers. The next task of this thesis is to operationalize the KYPO platform in a laboratory environment with a security scenario focused on DLMS/COSEM security. The security scenario that we have managed to create involves the interception of communication and the exploitation of at least two security vulnerabilities of the DLMS/COSEM protocol. All the programs and tools that we have used to achieve the objectives of this thesis have been summarized in more detail in a separate chapter, which is dedicated to the practical part of the thesis. The thesis describes the procedure and the problems that we encountered while completing the thesis assignment. The actual virtual scenario that we prepared runs on a server at the premises of the BUT. On this server is installed Cyber Range platform KYPO in all-in-one configuration. The created security scenario using the DLMS/COSEM protocol contains two users and one attacker located in the same network, as we have defined it. We used a simple text editor to define the network configuration and defined it for the KYPO platform in YAML format, which is used to automate the data in a form that is easy for humans to read. We also used the same YAML format to define playbooks, which serve as the easiest way in Ansible to automate repetitive tasks. We used them to install packages, update existing packages, and prepare the virtual environment to exploit DLMS/COSEM protocol vulnerabilities.

DLMS security suite implementation
Kohout, David ; Sláčik, Ján (referee) ; Mlýnek, Petr (advisor)
This thesis is focused on smart meters cyber security using DLMS Security Suite standard. Security is more important every day and DLMS specifies multiple methods of authentication and message encryption which is defined in Security Suites. For message creation there are multiple possible formats that can be used. For a better understanding all formats are analysed and compared using a specific example. Main part of this work is about making a testing application called VUT DLMS Tester which is used for testing this standard for real usage in distribution network. Whole development is cooperated with distribution companies and smart meter manufacturers. Application also implements higher levels of security which DLMS specifies. This application is used for testing multiple scenarios regarding security impact on data volume.

Information Security in Energetics
Straževský, Martin ; Lieskovan, Tomáš (referee) ; Hajný, Jan (advisor)
This bachelors thesis focuses on analysis of vulnerabilities of DLMS/COSEM protocol, DoS (Denial of Service) attack and load test execution on smart grid components -- smart meters. Thesis implements load tester application that can test given components load resistance based on input parameters, that affect predefined load profile consisting of phases and periodically checks whether the component is responding after each phase.

Possible Replacement Of Bulk Remote Sensing At The Point Of Delivery
Benešl, Lukáš
This article deals with a possible replacement of HDO (Bulk Remote Reading), fromthe distributor’s point of view and the customer’s point of view. A measurement, which simulatescommunication was performed from the smart meter to the end device (photo-voltaic panels, chargingstation for an electric car). The simulated measurement was divided into five scenarios, which arediscussed at the end.

Electric meter simulator with DLMS protocol
Tsymbal, Kateryna ; Gerlich, Tomáš (referee) ; Lieskovan, Tomáš (advisor)
This bachelor thesis is focused on getting acquainted with the DLMS/COSEM protocol and its functions. Furthermore, the Java programming language and the Raspberry Pi minicomputer are briefly introduced. The DLMS/COSEM protocol is used to simulate measurements using a smart meter, which ensures communication between the meter simulator and the concentrator. Communication provided by the DLMS/COSEM protocol is widely used in smart grids. The first part of the thesis discusses important information about energy networks and their relationship with smart meters, the importance of smart meters in modern networks and the role of smart networks, which are used for effective energy measurement in a particular area (e.g. for measuring electricity). Data measured in smart grids can be easily analyzed and used to make consumption more effective. The first part also mentions important information about the DLMS/COSEM protocol, the Java programming language and the Raspberry Pi minicomputer. In the second part of the thesis, a test environment is created for testing the smart meter simulator, which communicates using the DLMS/COSEM protocol with the concentrator and transmits the measured values to it. Measured values are manually defined for testing purposes using code changes in the Eclipse IDE. The aim of the work was to create a smart meter simulator that lists predefined values and passes them to the concentrator, which was achieved using the Gurux.DLMS library. Finally, an analysis of this communication was performed using Wireshark. This bachelor thesis is useful for a simple understanding of the DLMS/COSEM protocol and its use in smart grids.
