Identification technology of mobile phone devices using RFF

The vulnerability of the device identifiers, such as IP and MAC addresses, IMEI and IMSI codes, etc. creates threat to the information security, integrity and reliability. One of the solutions of this threat is usage of Radio Frequency Fingerprinting (RFF) technology for identifying wireless devices based on their unique radiation ?fingerprint? as opposed to their addresses or codes. In this work identification problems of mobile radio stations (from here in ? mobile phones) are being analyzed and identification methodology for identifying them based on the mathematical processing of front and rear fronts is proposed. All of this provides new insight in the field of signal detection and identification, thus by using this method only the original data is received. The purpose of this work is identification of a mobile phone, working on the DCS (digital cellular service) frequency, based on the phone´s radiated signal time characteristics.
