Web applications for user authentication
Vybíral, Petr ; Dzurenda, Petr (referee) ; Hajný, Jan (advisor)
The thesis deals with the problems of user authentication. The first chapter analyzes the problem of authentication, its methods and its utilization. The second chapter presents the different security options for communication. The chapter describes security, communication and authentication protocols. There is the 2D barcode QR Code described at the end of the chapter. The third chapter is devoted to ASP.NET technology, its development and possibilities of utilization. Attention is focused on web form and server controls. There is an analysis of elements of cookies and possibilities of their use. The last chapter consists of a practical part, which describes the development of a web application. There is a description of the parts of application, such as the database, the Web navigation, master pages and etc. in the following chapter. The cardinal part of the chapter consists of an analysis and implementation of forms authentication, the attribute authentication and authentication with QR code. Finally, there is a description of way how to secure the communication by using a certificate.

Applications for parallel processing in cryptography
Šánek, Jaromír ; Martinásek, Zdeněk (referee) ; Hajný, Jan (advisor)
This thesis is about parallel programming. In the first part of the thesis is compared speed of functions modular exponentiation from various C/C++ libraries for CPU. In the second part is transformed the LibTomMath library from CPU to GPU CUDA technology. For devices CPU and GPU is compared speed of processing the operation of modular exponentiation from modified library. In conclusion are created two applications “Client –Server” for computing the revocation function of the protocol HM12.

Web visualisation of cryptographic systems
Sikora, Marek ; Dzurenda, Petr (referee) ; Hajný, Jan (advisor)
This thesis deals with web technologies for interactive visualization of content. It discusses the new HTML5 specification, its animation possibilities using Javascript and their practical application for creating web pages. Furthermore, the work focuses on the development tool Adobe Edge Animate, through which we realize page design. The study also discusses cryptographic systems and protocol HM12. It displays a basic overview of the functionality of this Protocol. In the last part of the thesis describes the actual implementation of these two topics, namely the creation of web visualization – demonstrator of the cryptographic system including a fully operational model.
