Physical Layer Authentication Algorithm Based on SVM

The diversity of physical layer resources in wireless communication system provides a broad space for the research of physical layer information security technology. For the single judgment mechanism of cell reselection\cell handover, this paper makes full use of wireless physical layer channel characteristics, combined with SVM algorithm, a new physical layer channel authentication algorithm is proposed. The specific scheme is that according to the essential characteristics of 4G wireless channel and cell reselection\cell handover, combined with the hypothesis testing, using SVM to dig the channel index, so as to enhance the security of cell reselection\cell handover.
