Research on Physical Layer Security of Cognitive Radio Network Based on RF-DNA
Chao Wang, Yun Lin, Zhen Zhang · 2017
Cognitive radio (CR) is the enabling technology for supporting dynamic spectrum access. This sort of communication paradigm can utilize increasingly scarce spectrum resources more efficiently and has become one of the the hot issues of wireless communication in recent years. With in-depth research, some unique security risks of the CR network has been revealed. A new method named RF "Distinct Native Attribute"(RF-DNA) fingerprints can be used to address this problem. In this paper, We focus on the physical layer security of cognitive radio network and provide a summary of current techniques about RF fingerprinting.
