In this letter, an intelligent spectrum control (ISC) scheme is proposed to enhance the communication security performance in heterogeneous networks (Het-Nets), where the available spectrum can be efficiently managed by avoiding interferences flexibly with the aid of spectrum sensing technique. We analyze the security performance for the Het-Nets, and derive the closed-form expressions for the reliable transmission probability and the secrecy probability of the authorized user. Our numerical simulation results validate the accuracy of the analytical expressions, and imply that the Het-Nets with the ISC scheme can achieve a high security performance.
