Cryptanalysis of modern cryptographic devices
Fördős, András ; Člupek, Vlastimil (referee) ; Martinásek, Zdeněk (advisor)
The thesis focuses on power analysis of modern cryptographic modules. The first part contains a brief introduction to the topic of the power side channel and basic methods of analyzes. The text describes the process of comparison of modules and a short description of devices found. In the practical part two modules has been selected for the implementation of the encryption algorithm AES-128. The first module was the chip card Gemalto .NET v2 and the second one was the Raspberry Pi. A workplace has been created for these modules which allowed to measure the power consumption of the algorithm AES. Differential Power Analysis has been made using the captured results. In its conclusion the work presents the results in tables and samples of source codes. Graphs were made from the results captured on the Raspberry Pi and from the results of the Differential Power Analysis.

Data transmition security with BCH codes
Frolka, Jakub ; Tejkal, Vladimír (referee) ; Němec, Karel (advisor)
The bachelor thesis Data transmission security with BCH codes deals with class of random error correction cyclic codes which are able to protect data in binary form. BCH codes operate over algebraic structures called Galois fields. Encoding of these codes is same as encoding cyclic codes and can be used cyclic shift register, but decoding is more complex and can be done with many algorithms, in this thesis are mention three: Peterson algorithm, Matrix method and Berlekamp-Massey algorithm. In this thesis are described characteristics BCH codes, their usage in communication devices and their posibility implementation. An example BCH code which is able to correct four independent errors is created. This example is used for presentation of encoding and decoding methods. In the end is described implementation of data protection codec for FGPA devices.

XML based framework for transformation of Java source code
Šebesta, Jiří ; Parízek, Pavel (referee) ; Poch, Tomáš (advisor)
Goal of the thesis was to provide transformation framework for Java sources based on well established XML technologies. The framework defines XML Schema for representation of Java sources. Java 1.5 sources can be parsed and stored to XML. Means for transformation and analysis are based on the JAXB technology. Several example transformations (refactoring, predicate abstraction) are also part of the framework. The framework is able to transform XML files back to the Java sources.

IntelliSense Implementation of a Dynamic Language
Míšek, Jakub ; Parízek, Pavel (referee) ; Zavoral, Filip (advisor)
In the context of computer programming, the importance of computer assistance is being understood by many developer communities. Developers are e.g. using the same well known expressions or searching method signatures in library documentations. Code sense or IntelliSense methods make most of these actions unnecessary because they serve the available useful information directly to the programmer in a completely automated way. Recently, with the increased focus of the industry on dynamic languages a problem emerges - the complete knowledge on the source code is postponed until the runtime, since there may be ambiguous semantics in the code fragment. As a part of the Phalanger project the methods for syntax and semantic analysis of the dynamic code were designed, especially targeted for the PHP programming language. These methods produce a list of valid possibilities which can be then used on a specified position in the source code; such as declarations, variables and function parameters. This collected information can be also used to a fine-grained syntax highlighting.

Nursing care by children on biological treatment for Crohn's disease
KOUBOVÁ, Marta
This bachelor's work with the title: Nursing care of children with the Crohn´s disease going through biological treatment concerns with the care specifics which are necessary for the child´s patient during biological treatment giving. The Crohn´s disease has been along with the ulcerous colitis called by omnibus term for idiopatic intestinal inflammation characterised also by the abbreviation IBD from the English Inflammatory Bowel Disease. It refers to chronic inflammatory intestinal disease which affects intestine segmentally with intestine mucous membrane hitting in total thickness and has been characterised by remise and relapse phases. In the treatment connection, the aim is life quality improvement not only at the children but also at the adults. In the curative scheme the biological treatment has a high therapeutic potential which is from the costs viewpoint applied at relatively small sample of patients. For this bachelor´s work objects fulfillment was qualitative research investigation. Within research investigation were two aims determined. First goal was finding if nurses know specifics of the nursing care of children with the Crohn´ s disease. Second goal was to find out if nurses know biological treatment giving principles. On the basis of mentioned bachelor´s work aims the explorative questions were set: Which knowledge do nurses have of care at the children with the Crohn´s disease going through biological treatment? How do nurses ensure specific nursing care of children with the Crohn´s disease going through biological treatment? Which principles do nurses consider important at the care of the Crohn´s disease children going through biological treatment? The empirical part of bachelor´s work was processed in the form of data qualitative analysis using semi-structured talks and participated hidden monitoring. The research file consisted of eight respondents who participate upon applications of biological treatment at children with the Crohn´s disease diagnostics. Respondents answerred on the basis of own knowledge and acquired experience. The conversations were processed using open coding technique method pencil and paper. The categories and codes were processed into thought maps representing also respondents answers. The research investigation was added by semi-structured talk with the child´s gastroenterologist ensuring the biological care. The hidden participated monitoring was other used method taken at the same research file during the biological treatment application with focus on nursing care. Under the bachelor´s work will be organized the course on the basis of theoretical part and acquired results in the children´s ward of the České Budějovice hospital with orientation on nurses applying biological treatment and also on nurses unknowing in this problems.
