Security design for system of remote quality measurement of electric power
Jakubíček, Michal ; Koutný, Martin (referee) ; Mlýnek, Petr (advisor)
Bachelor thesis in the first chapter deals with the concept of quality of electric power and its parameters. The next chapter is focused on systems that used remote data collection and the current direction of evolution of these systems. The third of the thesis discusses the symmetric and asymmetric cryptographic systems and their main representatives. The asymmetric system is described by the principle of calculating RSA and Diffie–Hellman. The next part deals with selected libraries that can count large numbers. Through the establishment of key using the Diffie–Hellman with these libraries and the subsequent measurement should be proved whether optimized library is faster than the other libraries. The evaluation of the used library in terms of speed and memory consumption is inculded in the final chapter. The appendix include installation instructions for the libraries BigDigits, GMP and OpenSSL in Visual Studio 2010.

OpenSSL-based client-server system
Kohout, Jaroslav ; Janovič, Filip (referee) ; Malý, Jan (advisor)
Aim of this diploma thesis is study of possibilities of OpenSSL extension in PHP environment and its implementation in securing client-server system example. This system will be use to store confidential data. Whole system will be exemplar of securing against scale of attacks leads to gain private data.
