| 针对当前LTE-5G网络防御算法需要预设先决条件，且在多维攻击环境下难以实现防御行为自收敛等难题，提出了一种基于多维攻防博弈机制的LTE-5G网络防御算法。首先，对攻击行为进行大数据建模，综合考虑攻击行为数学分布特性，即DDos攻击特性，并精确匹配DDos攻击带宽，实现对攻击危害行为的确定性分析，提高网络主动防御性能，达到对攻击行为预分析的目的；随后，考虑到传统算法的网络收敛概率评估较差的问题，采取Q分析方式进行随机博弈，构建了Q博弈-单向数据攻击模型，成功获取单向数据攻击集合，并进行了攻击行为持续期间的纳什均衡，改善算法的网络防御效果。仿真实验证明：与当前LTE-5G网络中广泛使用的次高频载波指纹网络过滤防御算法（Secondary High Frequency Carrier Fingerprint Network Filtering Defense Algorithm，SHFCF-FD算法）、带宽峰值匹配过滤防御算法（Bandwidth Peak Matching Filtering Defense Algorithm，BPMFD算法）相比，所提算法具有更大的抗攻击带宽强与网络传输带宽，以及更低的裁决错误率低与信道误码率，具有很强的实际部署价值。 |
| 英文摘要: |
| In order to solve the problem that current LTE-5G network defense algorithms need presupposition preconditions, and it is difficult to achieve self-convergence of defense behavior under multi-dimensional attack environment, a LTE-5G network defense algorithm based on multi-dimensional attack-defense game mechanism was proposed. Firstly, the large data model of the attack behavior was built, and the mathematical distribution of the attack behavior, i.e. DDos attack characteristic was considered and matched accurately. Then the deterministic analysis of the attack damage behavior was realized, which greatly improves the network active defense performance and achieves the purpose of pre-analysis of the attack behavior. In order to solve the problem of poor network convergence probability evaluation, a Q-game-one-way data attack model was constructed by using Q-analysis method. The set of one-way data attack modes was successfully obtained and Nash equilibrium was carried out for the duration of the attack, which further enhances the network defense effect of this algorithm. Simulation results show that,compared with the secondary high frequency carrier fingerprint network filtering defense algorithm, and the bandwidth peak matching filtering defense algorithm, this algorithm has larger anti-attack bandwidth, network transmission bandwidth, as well as lower decision error rate and channel error rate, which has good practical deployment value. |
