NFC technology and its security
Mertlík, Tomáš ; Babnič, Patrik (referee) ; Rosenberg, Martin (advisor)
The first objective of this paper is to describe the Android operating system. The chapter presents history and architecture regarding to all versions of the operating system. The significant part of chapter is focused on security. The second main topic of this paper is analysing the NFC (Near Field Communication) technology. This technology is based on an older contactless system RFID (Radio Frequency Communication), so RFID is described either. The NFC technology chapter contains the description of usability, history and the definitions of physical layer, link layer and NDEF (NFC Data Exchange) data format, used for data transmitting. The next chapter is focusing on the analysis of the NFC vulnerability. It contains a possible attacks methods and solutions how to prevent them. The output of this paper is the projection and creation of an application, which allow sending an arbitrary data between two devices using the NFC technology. Additional Bluetooth technology can be used for larger files. In this case, NFC helps to create Bluetooth communication channel which is utilized for data transfer.

Android App for Security Monitoring of Communication
Klepáčková, Karolína ; Dobeš, Petr (referee) ; Herout, Adam (advisor)
This diploma thesis is focused on implementation of application for security monitoring of network communication of other applications in mobile device with Android platform. Provides users information about security risks that may harm his/her privacy or device. It uses a local VPN to tunnel all data sent to the wireless network. These can be linked to an application that has sent them because the Android kernel is derived from the Linux kernel and can be used to retrieve information about established network connections and the application identifier associated with the connection. This mapping allows to get more information about an app that is potentially dangerous for your mobile device.

Dynamic Security Policy Enforcement on Android
Vančo, Matúš ; Malinka, Kamil (referee) ; Aron, Lukáš (advisor)
This work proposes the system for dynamic enforcement of access rights on Android. Each suspicious application can be repackaged by this system, so that the access to selected private data is restricted for the outer world. The system intercepts the system calls using Aurasium framework and adds an innovative approach of tracking the information flows from the privacy-sensitive sources using tainting mechanism without need of administrator rights. There has been designed file-level and data-level taint propagation and policy enforcement based on Android binder.

Security mechanisms of OS Android utilizing the Kotlin language
Balaževič, Lukáš ; Mašek, Pavel (referee) ; Zeman, Kryštof (advisor)
Mobilné zariadenia sú v rámci technologickej histórie novinka a pri technológii, ktorá sa vyvíja tak rapídnym tempom a rastom používania je nutné dbať na zabezpečenie. Táto diplomová práca sa zaoberá rozborom bezpečnostných mechanizmov používaných v Android OS a komunikáciou medzi OS Android a vzdialeným serverom. Cieľom je preskúmať tieto mechanizmy a otestovať aké kryptografické metódy a postupy je najvýhodnejšie používať z hľadiska bezpečnosti s ohľadom na efektivitu. Tieto znalosti boli použité pre vytvorenie demonštračného systému, ktorý využíva vybrané zabezpečovacie mechanizmy a kryptografické postupy.
