Access security of wireless device is a great challenge to wireless communication networks, especially for radio frequency identification (RFID) and some other devices with limited computing power, which are faced with effective high-strength security challenges, and as an important non-cryptographic authentication technology, radio frequency fingerprinting (RFF) technology, for its full use of non-imitation radio frequency characteristics, attracts more and more attention. The generation mechanism of radio frequency fingerprint and the basic model of recognition system are described, and A RFF access authentication technology based on k-nearest neighbor (kNN) approach also is analyzed. In addition, the existing problems of radio frequency fingerprint recognition technology and the research direction of further improvement are pointed out.
