Abstract

Recent work in physical layer security focuses on the message transmission between legitimate nodes without revealing the transmitted data to the eavesdropper. However, this gives room for the eavesdropper to adapt its resources to combat with the legitimate nodes. Instead, in this article, we introduce a friendly spoofing aiming at misleading the eavesdropper with a falsifying message signal to mask the original message signal. The effect of such an attack on the legitimate receiver is analyzed. A joint power optimization algorithm is proposed to maximize the spoofing performance while maintaining the communication requirements of legitimate nodes. The numerical results indicate that the proposed system can work under favorable channel propagation cases, and we can provide 4 b/symbols with 99.9% coverage probability with both legitimate and misleading messages.
