Recently, the security of Internet of Things (IoT) has been an issue of greatconcern. Physical layer security methods can help IoT networks achieveinformation-theoretical secrecy. Nevertheless, utilizing physical securitymethods, such as artificial noise (AN) may cost extra power, which leads to lowsecure energy efficiency. In this paper, the hybrid precoding technique isemployed to improve the secure energy efficiency of the IoT network. A secureenergy efficiency optimization problem is formulated for the IoT network. Dueto the non-convexity of the problem and the feasible domain, the problem isfirstly transformed into a tractable suboptimal form. Then a secure hybridprecoding energy efficient (SEEHP) algorithm is proposed to tackle the problem.Numerical results indicate that the proposed SEEHP algorithm achieves highersecure energy efficiency compared with three existing physical layer securityalgorithms, especially when the number of transmit antennas is large.
