Karády, Gabriel ; Pavlíček, Luboš (advisor) ; Gála, Libor (referee)
The purpose of this thesis is to describe and compare password managers for users and small teams on different software and hardware platforms. It deals with the problem area of passwords in general, user habits, and comfort and password quality. It further introduces and categorizes password managers and compares a few of them by several criteria, from security -- used encryption and its cryptanalysis, user protection from malware -- through usability -- the abilities and ease of use of the tool, its integration with applications and the operating system -- up to teamwork enhancements -- synchronization abilities and sharing of both single passwords and password databases.

Internal Certification Authority
Kolb, Jiří ; Pavlíček, Luboš (advisor) ; Bumbala, Jan (referee)
With the rising number of internet users emerged the need for mutual authentication and secure communication. In the open environment of the Internet, this service is provided by a trusted third party using asymetric cryptography. This trusted third party - called Certification Authority - provides identification of the communication partners and the security of their communication through certificates it issues. Many large companies use certification authorities today. The goal of my thesis is the design and implementation of a CA for a small company, along with an evaluation of the benefits of introducing this new technology.

SAML and XACML as a New Way of Identity Management
Brechlerová, Dagmar
Today, the number of websites that are offering personalised web content ( some special information for somebody) are growing rapidly. To provide personalised content,websites require users to identify themselves, which is typically done by giving the user an account with an associated user name and password or other secure information. Security Assertion Markup Language (SAML) is an open standard defined by the OASIS. SAML provides a common language that online entities can use to universally share and exchange security information. Extensible Access Control Markup Language (XACML) is an XML based language for access control. The policy language is used to express acces control policies who can do what. SAML and XACML can be used for very complex identity management, for acces control policy. This paper is about the possibility how to use XACML and SAML for identity management. One model of authetication and authorization by XACML and SAML is presented here, too

Network access control
Kalina, Tomáš ; Pavlíček, Luboš (advisor) ; Knapovský, Miroslav (referee)
This bachelor's work discusses IT issues of network access control. The first part deals with the theoretical background of network access control. There are explained various ways of authenticating and authorization users. Thanks these function, it is possible to prevent unauthorized persons access to computer networks. Knowledge of these technologies is essential for understanding the next part of the work. The remaining part of the work is concerned with recommendations and draft network access control for various model situations, especially for the college of University of Economics, Prague. Specific examples are given for network infrastructure based on device of the 3com company.

Electronic signature for emails subscribing
Rychetský, Filip ; Toman, Prokop (advisor) ; Brechlerová, Dagmar (referee)
Práce se zabývá využitím elektronického podpisu k podepisování emailových zpráv a to přehlednou a jasnou formou s praktickými příklady. Zahrnuje obecnou charakteristiku elektronického podpisu jako takového, věnuje se kryptografickým základům, aby čtenář věděl, jakými metodami a principy je podpis zajištěn, a konkrétními možnostmi podepisování s důrazem na jednu variantu. Tato podrobněji popsaná varianta je konfrontována s dalšími možnostmi, zejména v oblasti výhod a nedostatků.

Comparsion of classic and modern authentication methods
Koudela, Radek ; Doucek, Petr (advisor) ; Cidlina, Jaroslav (referee)
Owing to the growing significance of data protection and informatics in general, the importance of information system security counts among the most actual topics at this time. The main goal of this work is to give a comprehensive overview of the issue of users' authentication, including current trends on this field. There are also described the principles and working methods of classic and modern authentication methods, and listed their pros and cons. The main benefit lies in the comparison of these methods as well as in the evaluation of their deployment. As a result of this are suggestions, which can managers take into account when deciding about the method of authentication, and a description of weak points that need an attention. One part of this work also includes a reliability and performance test of modern biometric device.

Autentizační metody - biometrie
Šlambor, Jan ; Doucek, Petr (advisor) ; Bébr, Richard (referee)
Práce sleduje a hodnotí různé metody autentizace. V práci je většina biometrických technologií uplatňovaných v současnosti. Sleduje biometrické technologie od svého počátku až po výhled do budoucnosti. Dále práce zahrnuje testování biometrických technologií podle vlastností jimiž disponují. V rámci testování biometrických technologií se objevuje multifaktorová analýza, která napomáhá určit podle přiřazených vah preferované biometrické technologie.
