Infrastructure of public keys
Bědajánek, Ondřej ; Malý, Jan (referee) ; Pust, Radim (advisor)
The subject of my thesis dscribes function and principles of the public key infrastructure as well as certificate authority. Under the operation system Linux was created self signed certificate authority. Web interface was devoloped in PHP for the purpose of the generation, distribution and rejection certificates. Configuration files for OpenVPN are included in the thesis and wireless security is achived by OpenVPN.

Certification authority
Herinek, Denis ; Sikora, Marek (referee) ; Zeman, Václav (advisor)
There is a lot of available services on the internet those need to be more secured and trusted. Public key infrastructure is used in sectors where are higher expectations in case of authentication, integrity and confidentality. It is almost impossible to imagine how internet banking or electronic signatures of important documents would work without PKI. There is a lot of open-source realisations of PKI created by users. Digital certificates as a part of PKI are issued by certificate authorities. This diploma thesis consists of open- source realisation of certificate authority and timestamping authority to demonstrate services which they provide.

Implementation of certification authority and digital signature
Troják, Martin ; Koutný, Martin (referee) ; Lambertová, Petra (advisor)
This master´s thesis deals with problems of certification authorities and digital signature. There are analyzed principles of digital certificates and certification authorities. It describes the the most widely used cryptosystems and hash functions, which are used in communications with certificates and digital signature. Analysis is focused on Public key infrastructure standard, which describes rules of creating of certification authority and digital signature. There is also described detailed principle of digital signature. Next chapters deals with studying of protocol SSL, principles of functions and usage of SSL. Practical part of this thesis realizes certification authority and information system. There is shown used software and configuration of it. Last part describes procedures during using aplication and her realization.

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.

Cryptography and implementation in Notes and Domino
Klusoňová, Eva ; Karakhalil, Mourad (referee) ; Ošmera, Pavel (advisor)
This bachelor's thesis deals with description of cryptography and Public Key Infrastructure in Lotus Notes/Domino. The goal of this thesis is to give a brief overview of cryptographic techniques including their implementation in Lotus Notes/Domino and to propose an appropriate examples for demonstration and education in cryptographic techniques. In order to demonstrate selected algorithms an open-source e-learning software CrypTool is used.
