Metody přenosu a zabezpečení dat pro aplikace v mobilních zařízeních

Abstract

The dissertation deals with data transfer and security applications in mobile devices. After introduction, it is composed a description of wireless technologies. Specifically, it is GPRS, WiFi and Bluetooth Technologies. Subsequently, it is given attention to introduction of the global positional system which will be used in the application data transferring representing the power consumption and location electromobile. The next section describes the options for detection and removal errors data as well as familiarization with the asymmetric and symmetric encryption techniques and description of an implementation AES. Then it is summarized the safety of wireless communication and transmission technology. Part of this work consists of design of laboratory workplace, mobile systems and the description of hardware modules. Experimental results are pivotal and verify encrypted and unencrypted data transfer from a mobile system using pre-described wireless technology. Experimental results are rounded off by applications which monitor the power consumption of electromobile. Contributions and achievements of this work are in conclusion.
