Most physical-layer authentication techniques use hypothesis tests to compare the radio channel information with the channel record of Alice to detect spoofer Eve in wireless networks. However, the test threshold in the hypothesis test is not always available, especially in dynamic networks. In this letter, we propose a physical-layer authentication scheme based on extreme learning machine that exploit...
We propose a novel authentication method based on sparse representation for the reconciliation in physical layer key Generation. In order to protect the legitimation of the channel, sparse representation is considered to enhance wireless security by using the unique channel location information. In contrast to traditional approaches, in this paper, we consider that this reconciliation channel is unauthentic,...
