Research on Dynamic Virtualization Distributed Mobility Management Method for LEO Satellite Network by Hongtao ZHU, Qing GUO

“…With the commercialization of 5G,the integration of satellite communication and ground 5G has become a key research direction in the industry.Low earth orbit satellite network can cover the whole world and communicate with anyone at any time and anywhere.It is an eff ective supplement and expansion of terrestrial cellular network.Especially,the deployment of low earth orbit (LEO) internet constellation such as OneWeb and Starlink accelerates the development of LEO satellite network.However,due to the high dynamic of LEO satellite and the fast change of its network topology,the network management problem caused by it has become the diff culty of LEO satellite application,and mobility management is one of the key technologies.How to build a mobility management mechanism suitable for high dynamic LEO satellite network is an urgent problem to be solved.Based on the idea of ground distributed gateway and satellite agent cluster,the dynamic virtualization distributed mobility management (DV-DMM) model was proposed,which was mainly used to solve the problems of poor scalability and single point failure of traditional mobility management.At the same time,it used satellite to build virtual gateway to solve the problem of building satellite ground station on the ground.…”

Super group peer selection algorithm in hybrid layered P2P streaming system based on evolutionary game by Jing CHEN, Bing ZHOU, Chen-shan REN, Xiao-she DONG

“…Due to high efficiency and good scalability,hybrid layered P2P architecture receives more and more impor-tance in P2P research and P2P streaming application fields recently.The blems about super peers selection are highly challenging because super peers must be selected from huge and dynamically changing network.A distributed super group peer(SGP) selection algorithm based on evolutionary game is proposed in this paper,in hich the SGP selection procedure is modeled based on evolutionary game framework firstly and its evolutionarily Moreover,a distributed Q-Learning algorithm (ESS-SGP) according to the mixed strategies by analysis is proposed for the peers to converge to the ESSs based on their own payoff history.Compared to the traditional random selected SGP P2P schemes,experiments results show that the proposed ESS-SGP algorithm achieves much better performance in terms of social welfare,average upload rate of SGPs,and keeps the upload capacity of the P2P streaming system increasing steadily with the number of peers increasing.…”

Survey of network-layer anonymous communication protocols by Liangmin WANG, Xiaoling NI, Hui ZHAO

“…An anonymous communication system is an overlay network built on the application layer and combining various privacy protection technologies such as data forwarding,content encryption,and traffic obfuscation to hide communication relationships between entities and forwarded contents.However,there is a deficiency in the balance between performance and security as an anonymous communication system operating over an overlay network.With the advance of the future internet architectures,it is possible to build an infrastructure-based anonymous communication system.Such anonymous communication systems design anonymity as network infrastructure services and provide encryption operations for routers,which can solve the part problem of scalability and performance limitations of anonymous network.They can also be called network-layer anonymous communication protocols.The existing network-layer anonymous communication protocols (LAP,Dovetail,Hornet,PHI and Taranet) were studied.The classification standard of network-layer anonymous communication protocols were introduced.Its innovation point and specific encryption ideas were briefly described,and how to keep balance between security and performance was analyzed.The shortcomings and advantages of these kinds of network anonymous communication protocols were also pointed out.Finally,the challenges faced in the development of anonymous communication systems and the problems that need to be studied in depth were proposed.…”

Research on Access Authentication and Re-Authentication Mechanism of User Devices in Terrestrial Default Scenario in Satellite Internet by Qiuyu BU, Jin CAO, Lifu CHENG, Ruhui MA, Hui LI

“…For the current user device access authentication mechanism requires ground participation to bring about large communication delays and poor scalability, a user device access authentication and re-authentication protocol in the ground default scenario in the space-ground integrated network was proposed, and further for the user device authentication process may occur in the power outage reconnection and AV asynchronization and other problems, a user device fast authentication mechanism and AV fast security synchronization mechanism under power failure reconnection scenario were proposed to ensured that users could safely accessed the satellite network and obtain related services.In the proposed scheme, the AV vector generated in the initial access authentication was used to assisted the re-authentication process to completed the authentication between entities without the involvement of the network control center, which guaranteed the communication system resilience.The formal verification tool Scyther showed that the proposed protocol was resistant to common protocol attacks, guaranteed the confidentiality and integrity of the communication process, and had a small signaling, computational, and bandwidth overhead, made it suitable for the satellite internet.…”
