One of the goals of sixth-generation mobile networks(6G) is to achieve a larger network coverage area. Satellite networks enable global coverage and aerial nodes such as Unmanned Aerial Vehicle(UAV) can serve as a supplement to ground networks in remote environments. Therefore, 6G networks are gradually evolving towards Space-AirGround integrated networks. The combination of UAV networks and satellite networks is a research hotspot in the field of Space-Air integrated networks. However, the combination of UAV networks and satellite networks currently faces many challenges in terms of security. The characteristics of large propagation delay and unstable communication links in satellite networks make them vulnerable to various attacks, including eavesdropping, tampering, and impersonation. Meanwhile, existing research on UAV networks mainly focuses on UAV-Ground networking authentication mechanisms, which are not suitable for resourceconstrained nodes in the Space-Air integration scenario. Therefore, based on elliptic curve public key cryptography and Chebyshev polynomial, we propose a secure networking authentication scheme for satellite nodes and UAV nodes in the Space-Air integration *** security analysis indicates that our scheme possesses security attributes such as mutual authentication, key agreement, identity anonymity, unlinkability, perfect forward-backward security, and resistance against various protocol attacks, among other security *** analysis also indicates certain advantages of our scheme over existing schemes in terms of signaling, bandwidth, and computational overhead.

A dynamical model is constructed to depict the spatial-temporal evolution of malware in mobile wireless sensor networks(MWSNs). Based on such a model, we design a hybrid control scheme combining parameter perturbation and state feedback to effectively manipulate the spatiotemporal dynamics of malware propagation. The hybrid control can not only suppress the Turing instability caused by diffusion factor but can also adjust the occurrence of Hopf bifurcation induced by time delay. Numerical simulation results show that the hybrid control strategy can efficiently manipulate the transmission dynamics to achieve our expected desired properties, thus reducing the harm of malware propagation to MWSNs.

对某新型160型模数式桥梁伸缩装置车辆行驶噪声进行了研究。为获得不同工况车辆驶过时系统响应规律,通过ANSYS分别对整体结构做瞬态分析、对中梁、边梁型钢做模态分析进行确定;之后将响应规律转化为声学激励。联合有限元法以及边界元法,利用ANSYS Workbench中Harmonic Acoustic模块进行声学分析,得到人耳敏感频率段不同远场处A声级曲线,最大A声级出现频率以及伸缩装置适宜安装位置。为验证仿真结果可靠性,与文献试验结果进行对比。结果表明,上述方法可以有效地评估伸缩装置车辆行驶噪声,结果具有较高可靠性。
