Authentication in Smart Grids
Janáč, Richard ; Šťastný, Ladislav (referee) ; Franek, Lešek (advisor)
This thesis is dealing with the possibilities of authentication of service engineers for Smart Grid network devices. The aim was to select the most appropriate type of authentication security token. Therefore, we examined the main principals of cryptography and described the algorithms used in the security token. At the end of the paper, the main three types of security tokens are compared. Further, the paper evaluates their use in equipment for the implementation of Smart Grid networks and token selection for subsequent processing demonstration applications.

Token based authentication
Loviška, Martin ; Šťastný, Ladislav (referee) ; Franek, Lešek (advisor)
Thesis is dealing with possibilities of user authentication using a security token to Linux console and web applications. Theoretical part of this work is devoted to cryptography basics, particularly asymmetric cryptography algorithms . Thesis generally describes aut- hentication methods and includes a brief categorization of smart card devices. The practi- cal part deals with SmartCard - HSM device setup for a client and creating own certificate authority using this device. Finally, it presents a demonstration deploying smart card login to Linux and web applications using tokens.

Lab of public key infrastructure
Slavík, Petr ; Lambertová, Petra (referee) ; Burda, Karel (advisor)
The aim of this thesis is to study and describe the theme of Public Key Infrastructure (PKI). Within the scope of minute PKI characterization there is a gradual depiction of particular structural elements, which are above all represented by cryptographic operations (asymetric and symetric cryptography, hash function and digital signature); then, there are also individual PKI subjects that are dealt with, like eg. certification authority, certificates, security protocols, secure heap etc. Last but not least there are a few complete Public Key Infrastructure implementation solutions described (OpenSSL, Microsft CA). The practical part of the thesis, a lab exercise, gives potential students the knowledge of installing OpenSSL system based certification authority. The next task educate students how to secure web server with certificate signed with own CA and also how to secure web server users‘ access control through certificates signed by the previously installed CA.

Možnosti implementace elektronického podpisu při víceúrovňové komunikaci v informačním systému
ŘEŘICHA, Jakub
This bachelor thesis deals with the use of the electronic signature for signing electronic documents in corporate practice. The theoretical part of the bachelor thesis introduces the problematics of electronic signature from the point of view of the new legislation of the European Union and the Czech Republic, outlines current technical possibilities and describes individual types of electronic signature. In the analytical part of the thesis, an overview of all evaluated means of the electronic signature was prepared, listing main advantages and disadvantages and their suitability for the communication levels given by the company information system. In addition, the thesis is focused on the mapping of current means and needs of electronic signature in the processing of documents in electronic form in the company information system environment. Further in the thesis a solution for identified needs of the company is also designed and this solution is demonstrated in the form of proof-of-concept.
