Legal protection of domains in relation to the right of indication
Greplová, Andrea ; Pítra, Vladimír (advisor) ; Růžička, Michal (referee)
63 10 Resumé Legal protection of domains in relation to the right of indication Domain names are a phenomenon of the last decade or two in which there has been an enormous increase in their popularity. We also have to point out the the misuse of domain names has also increased dramatically. The problems associated with domain names can be classified into several cathegories whereas the first one mainly concerns the content of a web presentation the second one is focused on the conflict arising from passing off and other intellectual property infringments. Due to technical requirements of domain names we can see that the number of available domain names is diminishing. This is a great opportunity for many individuals who are able to fully exploit the situation for their benefit. To counter-weight this trend there are initiatives aimed at enlarging the portfolio of available top level domains even though the effectivity of these initiatives can disputable. This piece of work is divided into two parts which overlap in some aspects. The first part is looking on a daomain name as a new legal concept not governed by an explicit statute thus wandering in between various schemes. This part attempts to define the domain name technically as well as legally focusing on its systematization and unveiling the basic...

Deniable encryption
Šebek, Marcel ; Tůma, Jiří (advisor) ; Krajíček, Jan (referee)
In the thesis we study deniable encryption, as proposed by Canetti et al. (CRYPTO 1997). Standard encryption schemes guarantee good security level unless the adversary is able to force the sender and/or receiver to reveal her secret knowledge. Assuming that the adversary knows true ciphertext, the se- cret inputs usually commits the sender/receiver to the true plaintext. On the contrary, deniable scheme is equipped with algorithms that provide alternative secrets which makes the adversary believe that different plaintext was encrypted. We recall the most important results in the area, in particular, the schemes of Canetti et al. (CRYPTO 1997), the scheme of Klonowski et al. (SOFSEM 2008) based on ElGamal encryption, schemes of O'Neill et al. (CRYPTO 2011), and schemes and impossibility result of Bendlin et al. (ASIACRYPT 2011). In ad- dition to presenting known results in an unified environment, we deeply investi- gate simulatable-encryption based schemes. In particular, we construct a scheme that is bideniable, and both of its induced schemes are receiver-deniable (in the flexible/multi-distributional setting). We also disprove part of the results of Bendlin et al. (ASIACRYPT 2011) by showing that their construction of fully bideniable scheme is wrong. This result is verified using computer simulation....

Specification Languages and Tools for Analysis and Verification of Security Protocols
Ptáček, Michal ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
This diploma thesis is focused on the analysis of security tools, which are commonly used for automatic verification of security protocols mainly. These security protocols are used for creation of private communication channells in insecured networks. Security will never be perfect, so finding of weaknesses in security protocols is always necessary and we need to improve these protocols. In this diploma thesis I have focused on looking for various verification tools on Internet. Subsequently, I have described each tool in this thesis, in way that each reader can easily find out, which tool is for him useful and which is not. I have summarized main benefits and drawbacks of each tool at the end of his description.

Facebook
Jůnová, Jana ; Švelch, Jaroslav (advisor) ; Vochocová, Lenka (referee)
The theme of this thesis is to assess the behavior while using the public communication network Facebook. The number of users of social networks increases, as well as number of photographs, videos and other input that is stored on the Internet. Particularly, young people try to maintain or further develop their contacts by this way. Perhaps it is a new type of social convergence, which is more or less based on voyeurism, or just an expression of self- realization. In any case this behavior impacts shaping the social relationships of networking users and their free time in a real life. Through a research of Facebook users, this work is looking for uncovering the thinking process of people when publishing private matters via the Internet. Its main goal is to explore the usage of Facebook, depending on the knowledge of its surround. First of all, it is interested in users' network settings experience. Because the adjustment of Privacy Policy may prevent risk of misuse of the social networking, which may lead to disruption of the privacy of all users involved. The main question of the thesis is to what extent the users are aware of the interaction of the environment that is "watching" them. Basicly, when talking about this topic, the most important question is notifying the process of blurring the...

Quantum computers and their impact on public-key cryptography
Lushnikova, Marina ; Ivánek, Jiří (advisor) ; Palovský, Radomír (referee)
The aim of this thesis is to study quantum computers and their impact on public-key cryptography. Crucial part of the work is dedicated to theoretical basis and definitions necessary for understanding the basic principles of quantum computers. The further chapters describe Shor's algorithm, explain the part of integer factoring problem in the security of current public key cryptographic algorithms, and show how to break the most widely used assymetric algorithm RSA by means of effective factoring. Last chapter provides comparison of classical factoring algorithms with Shors algorithm, mentions cryptography resistant to quantum computer attacks and discusses the current state of development in the field of qunatum computing. The conclusion summarizes both potential and real impact of quantum computers on public-key cryptography.

Protection of personal rights of individual in mass media
Knytlová, Kateřina ; Švestka, Jiří (advisor) ; Salač, Josef (referee)
11. Abstract in English This Master Thesis refers to the protection of personal rights of the individual in mass media. The main purpose is to analyse Czech legal regulations regarding this matter and to assess if the level of judicial remedy for the protection of personal rights is sufficient and appropriate. This thesis is focused on the collision of two fundamental rights, namely the right to protection of personal rights and that of freedom of speech and expression. Because of the growing influence of mass media, these rights are frequently at the centre of public debate and issues. The principal problem is which right should be prioritized. Both of them are established as fundamental human rights at the constitutional level therefore enjoy the same degree of protection. Attention is also paid to Spanish legal regulations of protection of personal rights of the individual in mass media. The important differences between the Czech and Spanish legal systems are pointed out throughout the whole paper. The thesis is composed of seven chapters. The first chapter is introductory. Chapter two deals with the protection of personal rights in general and explains this concept while enumerating law sources. Chapter three describes the protection of personal rights of the individual in mass media. It elaborates on...
