Authentication using a device with OS Android

By Martin Smíšek


This thesis describes the basics of cryptography including symmetric and asymmetric cryptography. It also looks into methods of authentication, using knowledge of some information, having any object and user specific proportions. The thesis engage in description of modern technologies NFC and BLE and shows, how to develop applications, working with them. It deals with the way of storing data used for cryptography, in the safe way. The access system created in the scope of this thesis, which is using Android powered device as an authentication object and communicating over NFC is described. The system can be divided into two parts. The first part works on the device powered by Android. It creates, resets and saves secret data safely and communicate with the other part. The second part is working in a terminal with connected RFID/NFC card reader. The task of this part is to communicate with the part on the Android device, attached to the reader and saving data of users and chambers centrally on the web server. It also creates logs in the form of text files and upload it to the FTP server
