Abstract


Cognitive radio is an intelligent spectrum sharing technology, through its real-time awareness surrounding wireless environment , intelligently adjust the communication parameters , opportunistic access to the spectrum holes in the premise does not affect the work of the main user , in order to effectively alleviate the shortage of spectrum resources problems. Real - time sensing and smart regulation are two unique features of cognitive radio , which also makes it the security problems faced by traditional network did not appear . In the process of spectrum sensing in cognitive user perception to the main user , immediately exit the channel . Attacker to exploit this characteristic emission mimic the signal of the main characteristics of users , to prevent other secondary users compete this band , and even interference to the primary user communications , and serious damage to the network performance . Smart regulation , cognitive radio according to the external environment adaptively adjust the parameters, through the study of history and accumulated experience to help make decisions . By malicious users tampering with the corresponding parameters to prevent cognitive radio network adaptive adjustment tampering can affect the network memory , and thus be misleading for future decision-making . On the basis of in-depth study of cognitive radio security imitation of a resist attack by the main user program , the program uses the idea of ??matching based on Hash were identified by the transmitted signals , in order to effectively identify malicious users . In addition, analysis of attacks by the objective function of cognitive radio , this paper designed a quadratic programming model for the implementation of the detection objective function tampered PSO (Particle Swarm Optimization) algorithm to construct a tamper-proof objective function is moderately valued function simulation results show that this method can effectively prevent the attack of the target function under the premise of the optimal configuration of cognitive radio .
