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.

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.

Public Key Infrastructure audit approaches
Pěnka, Michal ; Doucek, Petr (advisor) ; Červený, Vlastimil (referee)
The aim of this work is to introduce fundamental concepts of public key infrastructure. Basic requirements for communication and related problems are presented. The solution of these problems can be found in cryptography. Different types of cyphers and infrastructures based on assymetric cryptography are described. The infrastructure types involve hierarchical system of certificate authorities and the web of trust. Furthermore, there is a list and description of cryptography software which can be used in the field of public key infrastructre. The main topic of this thesis is the audit of public key infrastructure. Audit can be supported by several available standards, e.g. WebTrust for Certificate Authorities, ETSI TS 101 456, ETSI TS 102 042 and ISO 21188:2006. This paper systematically describes these standards and using statistical methods compares and evaluates their complexity.
