Access control system using multilevel authentication
Cvrček, Tadeáš ; Člupek, Vlastimil (referee) ; Dzurenda, Petr (advisor)
The master's thesis focuses on authenticated key agreement protocols and their implementation on MultOS smart cards platform and devices running Google Android operating system. Implemented applications use NFC (Near Field Communication) interface for communication with cellphone, Bluetooth technology for communication with smart watch and smart card as SAM (Secure Access Module) module in a verifier role. The source code is universal, so it is possible to use it in other projects.

Strong Cryptography on Smart Cards
Konečný, Jakub ; Burda, Karel (referee) ; Malina, Lukáš (advisor)
The diploma thesis is focused on cryptography with smart cards. It describes smart cards from hardware and software side. The thesis compares well known operating systems used on smart cards. Specified operating systems are widely analyzed. There is introduction to password authenticated key establishment protocols. PACE protocol is described in details together with implementation proposal. The implementation on the Basic card platform follows. In the end there is the time analysis of the implementation and further improvements are suggested.

Implementation of cryptographic protocols on smart cards
Moravanský, Michal ; Hajný, Jan (referee) ; Dzurenda, Petr (advisor)
The bachelor thesis is focused on cryptographic schemes using Attribute-Based Credentials, which try to minimize the negative impact on the protection of a user's privacy when using authentication systems. The aim of the bachelor's thesis was the implementation of two specified schemes on smart cards as a device with limited performance. Schemes differ only in the ability to revoke user. The practical part of this paper contains the analysis and selection of smart card platform and cryptographic libraries depending on performance. The work also describes the architecture of both schemes and individual protocols, including ongoing communication. The implementation of the Attribute-Based Credentials scheme was performed on a programmable smart card Multos (user side) and Raspberry Pi 2 (issuer and verifier side). The time complexity of the selected algorithms was also compared. In the end, the dependencies affecting the resulting efficiency and speed of the protocol were formulated.

Application for programmable smart cards
Broda, Jan ; Dzurenda, Petr (referee) ; Hajný, Jan (advisor)
The theoretical part of the bachelor thesis deals with the issue of secure attribute authentication, which places great emphasis on the protection of privacy and digital identity. The next part of the work deals with chip cards with MultOS operation system. The practical goal of this work is to create authentication application in C language using the attribute scheme CDDH19 and revocation scheme CDH16. The attribute scheme is based on signature scheme weak Boneh Boyen and on algebraic MAC funcion. For development it was used an interface Eclipse IDE with development environment SmartDeck. The final application will allow the users secure attribute authentication without any risks of leak of sensitive information. This application is implemented on MultOS chip card and tested in cooperation with the student, who programmed the verifier side on the microcomputer Raspberry PI.

Identification and authentication technologies
Miklánková, Zuzana ; Lieskovan, Tomáš (referee) ; Dzurenda, Petr (advisor)
The bachelor thesis deals with the analysis of currently available RFID technologies and smart cards. Summarized are types of identification and authentication radio or contact systems. The practical part compares measured RFID functional outputs and describes the implementation of multi-attribute authentication system using RFID technology and smart cards. For example, the authentication system can provide employees with access to the building, necessarily demonstrated by both the smart card and RFID tags.The system also includes user privacy elements, where identity of the user cannot be detected by captured communication.

Šánek, Jaromír ; Malina, Lukáš (referee) ; Hajný, Jan (advisor)
This work is dedicated the security of Electronic identity card and the platform of Multos smart card. In the first part are descripted symmetric and asymmetric cryptographic algorithms which are used in the area of eID. The second part is engaged the solution of electronic identity cards in Belgium, Estonia and Germany and Czech Republic. In this part are specified the eID, chips and digital certificates and applications. The part contains standard CEN TS 15480 European Citizen Card and access control mechanisms BAC, EAC and EAC v2. Next section is dedicated to describing the specification of passports with a chip and security of data stored on the chip. Last section is dedicated the practical part. In this part is described smart card Multos and development of applications for this smart card. Created application demonstrates the basic cryptographic functions. Between implemented functions are functions for generating random number, hash algorithm SHA-1, modular exponentiation and modular multiplication.

Electronic geocaching
Pavel, Lukáš ; Babnič, Patrik (referee) ; Burda, Karel (advisor)
The goal is to design and implement a concept of electronic geocaching with contactless smart card and cell phone with NFC interface. In the first chapter I describe geocaching and try to familiarize the reader with this game. The second chapter deals with the issue of smart cards, I describe here the contact and contactless cards and their security. In the third chapter, I describe use and security of radio communication interface NFC. In the fourth chapter, I describe the principles of symmetric and asymmetric cryptography and selected cryptographic techniques. In the fifth chapter is description of proposed solution for electronic geocaching with digital signature. The last chapter describes all created applications.

Cryptographic support of current programmable smart cards
Vančo, Petr ; Hajný, Jan (referee) ; Dzurenda, Petr (advisor)
This bachelor thesis focuses on benchmark tests of the MultOS smart cards. The characteristics of the smart cards are described at the beginning of the thesis, next part is about smart card communication. Then there is a comparison of operating systems. Next chapter is about cryptographic support for smart cards. Here is also described, which tools are used to develop for operating system Multos. The system for management and testing smart cards with MultOS was implemented in this thesis. Whole development process is described in last chapter, for smart card application, and for PC application with user interface.
