Physical layer authentication system security detection method

Abstract

The invention discloses a physical layer authentication system security detection method which comprises the following steps: transmitting a first carrier signal by a transmitting end, and obtaining asecond carrier signal from the first carrier signal through a channel; receiving the second carrier signal by a hostile terminal, obtaining the first false alarm probability based on the second carrier signal and the first hypothesis test condition, and obtaining the first optimal threshold value when the first false alarm probability is less than or equal to the corresponding upper limit based on the Neyman-Pearson theory to determine the first detection probability; receiving the second carrier signal by the receiving end, obtaining the second false alarm probability based on the second carrier signal and the second hypothesis test condition, and obtianing the second optimal threshold value when the second false alarm probability is less than or equal to the corresponding upper limit respectively based on the Neyman-Pearson theory to determine the second detection probability; And the receiving end obtains a security authentication probability based on the first detection probability and the second detection probability to detect the security of the physical layer authentication system.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication, in particular to a security detection method of a physical layer authentication system. Background technique [0002] Verifying the authenticity of the transmitter is a basic security requirement. The traditional authentication technology is based on the encryption mechanism and performs identity authentication on the upper layer. Compared with the traditional authentication technology, the physical layer authentication technology has two main advantages: First, the physical layer authentication technology obtains higher information theory security by introducing noise interference to the hostile end. Secondly, physical layer authentication can avoid any operation on the upper layer of the computer to obtain higher efficiency and better compatibility. [0003] The performance evaluation of physical layer authentication technology is mainly based on three characteristics: ...

Problems solved by technology

[0004] However, current research on the performance analysis of physical layer authentication is far from perfect

Since these three characteristics are usually discussed separately, it is difficult to systematically analyze the influence of parameters on the final performance in a specific physical layer authentication technology, and to compare the performance of different physical layer authentication technologies fairly under the same channel conditions. Performance also becomes difficult
