Data transmition security with general linear block codes
Dzurenda, Petr ; Tejkal, Vladimír (referee) ; Němec, Karel (advisor)
This work deals with problematic basic characteristic common linear block codes, concretely with creation generating and controlling matrix and individual ways decoding common linear block codes and then are theoretic knowledge used in the next part bachelor’s thesis. Next part this work is bent on the concrete layout of common liner block code satisfactory specifications by submission. In this part it can by find way haw create generating matrix be able to correcting tree single errors then create control matrix for decoding and correct network for correcting errors. Programs are used in this work are explained there. In the end this part is example of coding and decoding. Lastly work is realization codec. In this part is description of coder and decoder realizations. This codec is simulating by program Matlab Simulink in part five. In last part are create boards of printed circuits by program Eagle for coder and decoder.

Anti-Error Coding Systems with Block Codes
Pacher, Jakub ; Zezula, Radek (referee) ; Němec, Karel (advisor)
This work deals with selection and proven suitable error-correcting code securing aggregating errors. First we give analysis anti-error coding system and requirements rapid/fire at them. The next text is focusing on survey and characteristics often used codes, mainly Fire, Hamming and two BCHs codes. After an explanation of Hamming code use, the text describes verification of proper function anti-error system in the MathCad enviroment.

Decision-making about cloud service providers with respect to data security
Račanský, Jan ; Matuštík, Ondřej (advisor) ; Böhmová, Lucie (referee)
Organizations that during the past years become accustomed to run its services on its on-premise solution, have increasingly to decide if they will in these days continue to operate their IT services in this way, or take advantage of new opportunities for cloud-based solution. However, the transition to this new technology, which entrusts their data into the hands of external companies, accompanied by a fear of security of their sensitive data. The main objective of this thesis is to propose a reference model that will assist organizations in their selection process of cloud service providers with respect to data security. In conclusion the quality and usefulness of this reference model is validated by knowledge and information, which are obtained during interviews with IT specialists.

Security of mobile devices running Android
Novotný, Josef ; Pecinovský, Rudolf (advisor) ; Pavlíček, Luboš (referee)
The main subject of this thesis is the security of Android platform mobile devices. The goal of the thesis is to design and develop an application that will check given devices from the security point of view and to check the security of applications developed as the subject of theses created in the last few years at the University of Economics. In the first part of thesis there is an analysis of ways to secure the Android platform devices and applications and ways to attack them. Both the offline and the client/server architecture applications are also taken into consideration. The next part includes a security analysis of the selected application based on the beforehand determined criteria. An analysis and development of the application designated to examine the security of the given device is next. The outcome of the thesis is an easy to use application that can be launched on the mobile devices running Android 2.2 Froyo and higher.

Project migration of user data in a multinational company in the transition from Windows XP to Windows 7
Plzák, Vojtěch ; Bruckner, Tomáš (advisor) ; Nový, Josef (referee)
This work deals with user data migration in large companies. The actual content is preceded by a theoretical part, which summarizes the terms in the field of projects, migration and corporate directives. The practical part contains information which provides comprehensive knowledge gained from a realized project. The following chapters include defining the scope of the project and ensuring the security of data during implementation. Data security is conceived from both the perspective of stealing data from a hard drive and from the perspective of data loss caused by, for instance, improper handling. The fourth chapter is devoted to the migration process itself, recorded exactly as I applied it myself. A part listing the critical factors that I have met and suggestions for addressing them follows. Conclusion is devoted to a summary of the whole work.
