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.

Wireless technology NFC
Junga, Tomáš ; Fortinová, Jana (advisor) ; Pavlíčková, Jarmila (referee)
The paper deals with NFC technology. The thesis is divided in theoretical and practical part. Theoretical part focuses on NFC technology and Bluetooth supported by basic definitions. It also provides NFC's brief history, its advantages as well as disadvantages and utilization of this technology. In the next part, thesis examines safety of such technology with focus on potential attacks. Furthermore paper contains comparison of NFC and Bluetooth technologies. Practical part of the thesis aims at showing real example of how the NFC tag works with NFC device, which is also one of the main objectives of this work. In the latter part, paper deals with future development of this technology with possible real life applications. The main contribution of this work is represented not only by the pure introduction of NFC technology as a way of accelerating data interchange but also by the possibility of wide adoption of this system in society in form of its everyday use.
