Abstract:

The authentication method of traditional wireless communication mainly depends on the upper layer encryption mechanism, which cannot guarantee the real-time processing of the system and the security of the physical layer. This paper presents a physical layer security authentication method based on physical unclonable function(PUF), generating authentication labels in real time by using the uniqueness of challenge-response pairs (CRP), which is the intrinsic hardware feature, and the randomness of information. In the receiving end, the received signal and the transmitter are identified by comparing the received and generated tags, which provides effective protection for the information security of the physical layer. This method does not need complex cryptographic algorithm and reduces the calculation in the communication process. Simulation results show that this method has high use value.
