Application for Testing Smart Meters
Kohout, David
This paper presents our developed application for smart metering, which we are using to test the interoperability of different smart meters, compatibility with transmission technologies, to measure data volumes, test data security, and also ensure data security through the whole life-cycle of smart meters. The paper concludes with future development and planned features of our application, which is already being used for testing smart metering technologies at the Smart Grid Lab at BUT.

Athlete as an entrepreneur
Perušič, Ondřej ; Horáček, Tomáš (advisor) ; Kohout, David (referee)
Athlete as an entrepreneur Abstract This thesis is focused mainly on the problematic of the athlete's role as an entrepreneur from the perspective of business law. Its goal is not only to describe the current situation and answer some questions related to the topic, but also to point out some very problematic facts and think about possible solutions to the very unsatisfactory situation of today's legislation on professional sports. In the first two chapters I would like to underline some specifics of the athlete's position as an entrepreneur and how it differs from the classic, normal entrepreneurship that we know. I would also like to emphasize quite serious lack on the field of terminology, that makes the necessary process of change even more difficult. Next two chapters will be focused on the two main aspects of athlete's entrepreneurship. First one concerns the contracts and obligations he is taking part in and the typical structure of legal bonds that it creates. In this chapter I would also like to describe the specific types of contracts that are either the most common ones or somehow unusual and specific for sports. The second chapter out of the two mentioned above will focus on the litigations that arise from these contrats or other legal reasons. I will only briefly introduce the problematics of...

Secure reading of smart meters
Chaloupková, Denisa ; Mlýnek, Petr (referee) ; Kohout, David (advisor)
The work deals with the implementation of the secure push mode of the DLMS standard. It introduces the DLMS/COSEM standard, contains a theory for message security and describes how push works and its attributes. The Gurux library in Java is used and the example gurux.dlms.push.listener is modified. The Raspberry Pi platform is used as the server. Wireshark and the Gurux DLMS Translator available in Gurux GXDLMSDirector were used to verify security of a push message. Subsequently, push messages are compared in terms of their size according to the type of security used. The larger the content of the data sent in the message, the smaller the additional data needed to secure the messages in proportion to the total volume.

Cyber security for power engineering
Sedláková, Dáša ; Kohout, David (referee) ; Mlýnek, Petr (advisor)
Due to the IT and OT networks convergence, industrial systems are becoming vulnerable to different forms of security threats including rapidly growing cyber-attacks. Thesis is focused on an analysis of security recommendations in IEC 62351, vulnerability testing of industrial communication protocols (e.g., IEC 61850) and mitigations proposal. An ATT&CK framework for ICS was chosen to become a methodology base for vulnerability testing. ATT&CK tactics and techniques were used to practically test vulnerability scans, SMV time synchronization, GOOSE spoofing, MMS Man in the Middle and ICMP Flood attacks. Attacks tested were evaluated with a risk analysis. Subsequently, mitigation measures were proposed on several levels (OT, IT, perimeter and physical level).

Legal relations between professional athletes and sports clubs in team sports
Růžička, Hynek ; Kohout, David (advisor) ; Beran, Karel (referee)
Legal relations between professional athletes and sports clubs in team sports Abstract The presented rigorosum thesis focuses on the legal relations between professional athletes and sports clubs in team sports. The thesis investigates professional sports contracts concluded between professional athletes and highest-level sports clubs in the Czech Republic and abroad across various fields of collective sports, in particular, contracts in ice hockey, football, basketball and cycling. The presented thesis compares domestic contracts with international professional sports contracts concluded under the most prestigious sports competitions in the USA and contracts from the Finnish top ice hockey league. The legal status of professional athletes in the Czech Republic as subjects of legal relations is examined in detail before the professional sports contracts are assessed. Consecutively, the admissibility of particular contractual arrangements under specific legal regulations is evaluated. In particular, the legal status of professional athletes is analysed in the light of the case law of the supreme courts of the Czech Republic. Moreover, the CJEU case law and its long-standing decision-making practice in this area are considered. The interpretation includes an assessment of national, European and international...

Legal aspects of the Jerusalem procedure with Adolf Eichmann
Kohout, David ; Seltenreich, Radim (advisor) ; Císař, Jaromír (referee)
-89- 6 English Résumé, Key Words Právní aspekty jeruzalémského procesu s Adolfem Eichmannem Legal Aspects of the Jerusalem Trial of Adolf Eichmann Résumé In this diploma thesis I tried to provide a more or less complete overview of legal aspects of the trial of Adolf Eichmann and to point out some of its extra-legal consequences too. This trial took place in Jerusalem and together with the pre-trial proceedings it spanned more than two years. On the course of those two years (and predominantly during the trial proceedings) many interesting legal issues arose. Firstly, the sole fact of how the Israeli secret agents had managed to seize Eichmann in the territory of another sovereign state (Argentina) amounted to a breach of the public international law and led to an international dispute that ended up before the Security Council of the United Nations. As to the trial before the national courts of Israel (the District Court in Jerusalem and the Supreme Court of Israel), many important legal issues were raised too. Besides the objection of the counsel for the defence that Israel's right to try Eichmann precluded on the mere fact of his abduction from Argentina in breach of the international law, the courts were confronted with other jurisdictional matters as well. Both of the courts strived to overcome the...

Legal-Historical Aspects of Punishment of Nazi Criminals on the Background of the Adolf Eichmann Trial
Kohout, David ; Seltenreich, Radim (advisor) ; Vojáček, Ladislav (referee) ; Horák, Záboj (referee)
in English Dissertation Thesis David Kohout: Legal-Historical Aspects of Punishment of Nazi Criminals on the Background of the Adolf Eichmann Trial This Dissertation on the topic of "Legal-Historical Aspects of Punishment of Nazi Criminals on the Background of the Adolf Eichmann Trial" seeks to analyze the main approaches to the prosecution and punishment of the Nazi crimes. It was chosen to use the trial of Adolf Eichmann in Jerusalem in years 1961 - 1962 as a connecting thread of this whole work. It was so not only due to the individual remarkableness of the trial but also due to the fact that it was in many ways a very illustrative for the previous legal development until that time. Additionally, many commentators of this trial attribute it a great impact on the renewal of the interest in the prosecution of former Nazis who were implicated in perpetration of crimes committed until 1945 and who remained at large after the end of war. Therefore this Thesis goes beyond the Eichmann trial and focuses on its broader context in material but also personal sense (in the text it often referred to cases of prosecution of close collaborators of Adolf Eichmann). In the opening chapters this Dissertation, however, starts with events that go far back in time before the Adolf Eichmann trial. This is for the...

Impact Of Cyber Security On Data Volume In Smart Metering
Kohout, David
Smart metering is a new way of monitoring power grid and it can make billing of electricityconsumption much easier. These systems can be marked as elements of critical infrastructure,so it needs to be protected. For cost-effective communication with smart meters, we need to findcompromise between frequency of reading, data volume and cyber security.

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.
