The security risks of authentication methods
Dzurenda, Petr ; Babnič, Patrik (referee) ; Rosenberg, Martin (advisor)
Master's thesis deals with the security risks of current authentication methods. There are described methods which are based on user's knowledge and ownership of authentication object and biometric authentication method. The practical part of this Master's thesis deals with a specific design of authentication system based on protocol ACP, when the user proves his identity by smart card on provider assets, which is represented by ACP portal on the user's computer.

Security of authentication protocols
Tran, Minh ; Člupek, Vlastimil (referee) ; Dzurenda, Petr (advisor)
This thesis deals with the security of authentication protocols. The aim of the thesis is to analyze current security threats and attacks on current card systems mainly JavaCard and Mifare. And then to create a mobile application using Android platform with NFC and HCE functions, which realises the founded attacks. These attacks are relay attack and card cloning. Mobile side of the application is written in Kotlin programming language and server side in JavaScript, EJS and CSS. In the end attacks on EMV and access system of an unnamed university are demonstrated.

Contactless microcomputer card as a hiding place for geocaching
Vertaľ, Damián ; Dzurenda, Petr (referee) ; Burda, Karel (advisor)
This master’s thesis focuses on the possibility of using contactless smart cards as an electronic hiding place in an activity known as Geocaching. The first part explains the theoretical knowledge about cards, smart card programming, the development of android applications for communication with the smart card using the NFC interface and usage of eliptic curves to sign digital messages. The second part is dedicated to the design of a Java card application and an Android application, which are able to communicate

Modern access control system
Vomáčka, Martin ; Hajný, Jan (referee) ; Malina, Lukáš (advisor)
The thesis describes the design of scheme for access system with user authentication via smart cards. The first chapter explains various types of identification items used for authentication of users and different types of readers and terminals, followed by chapter 2 with a deeper insight on smart cards with focus on their types, what internal structure and principle of communication with card readers are used, etc. with primary focus on Java cards. The third chapter describes Java Card cryptography - especially elliptic curve cryptography used on this platform. The fourth part focuses on PACE protocol with subsections dedicated to the individual parts of the protocol and its applicability to smart cards environment. Chapter 5 explains the proposed design of the authentication scheme elaborated in the thesis, including a detailed description of specific parts, their funcionality and exemplary usage in the created applications.

Mobile Application for Encrypted Calls
Jonáš, Jiří ; Malina, Lukáš (referee) ; Hajný, Jan (advisor)
The thesis is focused on implementation of aplication for secure telephone communication on data network. Application is developed for operating system Android. For call management is responsible signaling protocol SIP and for transfer of voice data is used protocol RTP. For security of call is first created cryptografic key for symetric cryptography. After generating key is established call, which is encrypted by symetric cipher AES. Encrypting between communicating sides is provided in application or on microSD card. Part of solution is measurement of speed of cryptographic primitives, which are used for secure call.

Multiaplication smart cards
Meluzín, Ivo ; Malina, Lukáš (referee) ; Sobotka, Jiří (advisor)
The goal of the first part of the thesis is to describe the options of wide usage of chip cards in different segments of our life. Consequently it is necessary to mention hardware and software equipment of smart card, its communication with terminal and data security. In this thesis we focus on Java Card environment in which we will try to create two applications, one for electronic purse and the second for user identification. Basically, we need to mention multiapplicational rules of sharing data and objects. At the end of the thesis we are focusing on the possibility of mutual interference between the applications and on protection against attacks. Also future applications of this technology are described.
