This thesis deals with contemporary approaches that provide higher protection of privacy of users. It focuses mainly on a group signature. In the practical part of this thesis I designed and implemented PS that is enable to gather information with the help of signal of a mobile device. The application was designed in accordance with fundamental cryptographic requirements such as the authenticity and the integrity of transmitted data. The anonymity of users is guaranteed through an application layer (the group signature) as well as through a network layer (Tor).

The subject of this dissertation is the assessment and optimization of water distribution in the group water supply. The water supply networks are located in the Water Association of Babicko, former district of Uherské Hradiště, region of Zlín. The objective of this work is the unification of the entire documentation for all projects, creation of a hydraulic model of water supply network and subsequent verification of the existing capacities and pressure ratios. This work is particularly focused on the evaluation of pressure ratios at the highest and the lowest points of villages, whether they correspond to the legal limits, and subsequent design of a possible division to pressure zones.

The present diploma thesis focuses on the relation of the bilingualism and the cognitive style of field dependence/independence. Its first theoretical chapter deals with the issue of cognitive styles, in particular field dependence/independence, its history, possibilities of testing, namely the Embedded Figures Test and its group and online modifications. The second chapter of the theoretical part provides a characteristics and description of the phenomenon of bilingualism, its classification and a review of selected studies of bilingualism in relation to cognitive abilities and with the concept of field (in)dependence. During the former researches, higher tendency to the field-independence in youth non-adult bilinguals was proved. The purpose of the empirical part of this thesis aims to find, using the Online Group Embedded Figures Test, if the bilinguals still differ in this higher tendency from monolinguals in the adulthood. Based on the sample of 30 adult individual natural bilinguals, whose results in the Online GEFT test were compared to the results of 30 adult monolinguals in the same test, a statistically significant difference was not proved. From this result we can claim, that in adulthood, the difference of the field-independence between bilingual and monolingual population tends to...

Values, especially the value of education, can be called a timeless theme. Changing historical periods brought about changes in the concept of educational value. Originating in Ancient Greece, the concept of educational value is as relevant as ever even today. This paper is devoted to this topic. In the Introduction - theoretical part - we aimed to look at the common values from the perspective of different disciplines. The following part discusses such terms as the system of values, its hierarchy and value orientation. This thesis also focuses on socialization and transmission of values, mostly in the family. This inherently includes parent-child relationships and educational styles. We did not avoid the issues of perceptions of moral standards specific to adolescents, their choice of vocational preparation etc. Also mentioned are the concepts related to education and educating. In the practical part, we discuss research methodology, conducting the interviews and their coding according to predetermined criteria. After this analysis, the thesis deals with the comparison of personal students' testimonies across individual classes as well as entire schools. The results of the research are presented in the Conclusion, which summarizes and compares the general and personal views on the value of...

The diploma thesis is primarily focused on risk analysis and risk assessment of drinking water supply systems. In the research, the issues of risk analysis and risk assessment considering world and Czech Republic, were summarized. Software WaterRisk, which was developed by BUT Brno, was used for risk assessment of a particular water supply system in Třebom. Next, the thesis is aimed on technical audit of water tanks. There was a research of technical audit in the world and in the Czech Republic. Also assessment of technical audit of a particular water tank, which had to be anonymized, using software TEAwater is described in detail. Two conditions were considered: before and after reconstruction.

Anonymous authentication is a mean of authorizing a user without leakage of user personal information. The technology of Anonymous Authentication Systems (AAS) provides privacy of the user and yet preserves the security of the system. This thesis presents the basic cryptographic primitives, which can provide anonymous authentication. Among these primitives there are usually some asymmetric cryptosystems, but an essential part of anonymous authentication is based on zero knowledge protocols, blind signature schemes, threshold group schemes, etc., that are presented in Chapter 1. Generally, Anonymous Authentication Systems have application as electronic coin, electronic cash, group signatures, anonymous access systems, electronic vote, etc., which are analyzed and presented in Chapters 2 and 3. In the practical section, the implementation (in the environment .NET in C#) of the AAS system is presented and described in Chapter 4, which is being developed at the FEEC BUT.

This thesis discusses the possibility of ensuring the safety, integrity and authenticity of data communication with respect to user privacy. This thesis describes the fundamentals of smart grid networks with capabilities of existing forms of security to communications that have been chosen as a target for application deployment of group signatures to ensure the security, integrity and authenticity of data communications. It describes the concept of a zero-knowledge and cryptography primitives. Further, the basic principles are presented, the history of development, and various schemes are compared based on the construction and performance. The second part is given to the deployment and optimization of group signatures for computationally limited devices. Within the draft report were to be implemented in the Java language chosen scheme HLCCN, DP and BBS. They were then tested under various platforms which were measured and evaluated performance parameters of the schemes. The optimization of the work is focused on the times of signatures, which are critical to a smart grid system. Under the platforms are deployed pre-processed pairing optimization methods and other methods resulting from the deployment platform as JPBWrappera and native libraries to deliver more efficient times of sgnaiture. At the end of the thesis are evaluated achievements of optimization methods and the appropriateness of the deployment of smart grids.
