【摘要】 无线设备的接入安全是当今无线网络安全的一个严重挑战,尤其是RFID等计算能力有限设备,更受到有效高强度的安全挑战。射频指纹识别技术作为一种重要的非密码认证技术,因其充分利用不可模仿的射频特性实现认证,而越来越受到重视。因此,介绍射频指纹的产生机理和识别系统的基本模型,对国内外新近提出的射频指纹识别方法进行介绍和分析,指出了射频指纹识别技术现存的问题及后续改进研究的方向。更多还原

【Abstract】 Access security of wireless device is a great challenge to wireless communication networks, especially for 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 fingerprint recognition 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 several new methods for radio frequency fingerprint recognition also analyzed. In addition, the existing problems of radio frequency fingerprint recognition technology and the research direction of further improvement are pointed out.更多还原
