Problems solved by technology

However, the disadvantage of this technology is that the current software authentication method is easy to imitate, and this vulnerability is also easy to be exploited by malicious attackers to launch PUE (Primary User Emulation) attacks, resulting in information leakage or long-term illegal use of spectrum. Brings great trouble to network management

Abstract

The invention discloses a mobile phone individual identification method based on bispectrum features and a boosted tree. After sampling and preprocessing all samples, four integral bispectrums are calculated to obtain a feature set for training a convolutional neural network. Then divide the feature set into training feature set YTrain and test feature set Ytest in proportion, then use Ytrain to train the boosting tree, and use the fitting residual of the boosting tree as the target of the next round of training, and finally use the trained boosting tree The classification decision is made on the test set YTest, and finally the mobile phone individual recognition result is output.

Description

technical field [0001] The invention belongs to the technical field of communication, and more particularly, relates to a mobile phone individual identification method based on bispectral features and boosting trees. Background technique [0002] The individual identification of the communication radiation source determines the individual radiation source that generates the signal by measuring the characteristics of the received signal, which is defined as "the ability to associate the unique electromagnetic characteristic of the radiation source with the individual radiation source". The individual characteristics of the radiation source are generally due to the slight differences between its internal components (such as the nonlinearity of the device, the instability of the frequency source, and the spurious output, etc.), which is also called the "fingerprint" of the communication signal. , refers to the feature in the communication signal used to identify the identity of...
