| 2 | 认知无线网络中收敛感知算法安全性检测显示文摘分布式认知无线网络中,攻击者通过篡改本地频谱感知数据发起频谱感知数据篡改攻击,影响网络中其他节点的数据更新,导致频谱决策的错误.针对分布式认知无线网络中的收敛感知算法进行安全性检测.仿真数据表明,如果网络中存在攻击者在数据收敛后期开始发起频谱感知数据篡改攻击,将会诱使收敛感知算法最终收敛于攻击者提供的感知数据,使局部网络中所有认知用户对频谱感知数据做出错误的判断.最后,针对认知无线网络中频谱感知的特点,考虑影响感知数据更新的因素,给出了分布式认知无线网络中频谱感知的安全补充建议. | 李红宁 裴庆祺 李子 | 2014 | 西安电子科技大学学报2014,41,3: | 3 |
| 3 | A Differential Game Based Approach Against Objective Function Attack in Cognitive Networks显示文摘We study the problem of defense strategy against Objective function attack(OFA) in Cognitive networks(CNs), where the network can be operated at the optimal state by adapting the parameters of its objective function. An OFA attacker can disrupt the parameter adaptation by interfering measures, which results in some operating parameters of the objective function deviating from their optimal settings. We first model the interactive process between the OFA attacker and defense system using differential game theory, and propose a defense strategy by introducing a new metric, namely, threat factor. Then,we obtain the optimal defense strategy by proving the existence of the saddle point of the proposed model. Moreover,this defense strategy is scale-free such that it can conquer a large number of OFAs in a decentralized way. Finally, we conduct extensive simulations to show that the proposed approach is effective. | FENG Guangsheng LIN Junyu ZHAO Qian WANG Huiqiang LYU Hongwu ZHAO Xiaoyu HAN Jizhong LI Bingyang | 2018 | Chinese Journal of Electronics2018,27,4: | 2 |

| 7 | A Distributed Strategy for Defensing Objective Function Attack in Large-scale Cognitive Networks显示文摘Most of existed strategies for defending OFA (Objective Function Attack)are centralized, only suitable for small-scale networks and stressed on the computation complexity and traffic load are usually neglected. In this paper, we pay more attentions on the OFA problem in large-scale cognitive networks, where the big data generated from the network must be considered and the traditional methods could be of helplessness. In this paper, we first analyze the interactive processes between attacker and defender in detail, and then a defense strategy for OFA based on differential game is proposed, abbreviated as DSDG. Secondly, the game saddle point and optimal defense strategy have proved to be existed simultaneously. Simulation results show that the proposed DSDG has a less influence on network performance and a lower rate of packet loss.More importantly, it can cope with the large range | Guangsheng Feng Junyu Lin Huiqiang Wang Xiaoyu Zhao Hongwu Lv Qiao Zhao | 2015 | 国际计算机前沿大会会议论文集2015,,1: | 0 |
