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.…”

Vers une modernisation énergétique : territorialisation conflictuelle et gouvernement de la critique des nouvelles infrastructures énergétiques en moyenne montagne by Jimmy Grimault

“…Opponents to infrastructure which symbolises ecology for the sake of ecology are picking back up the gauntlet of environmental protest and proposing new, competing technological trajectories (Fressoz, 2012). To ensure the smooth deployment of energy infrastructure, eco-modernisers therefore need to rethink their acceptability strategies (Oiry, 2017). …”

Multi-User Detection Algorithm for Asynchronous Non-Orthogonal Multiple Access Based on Gaussian Approximation by Peisen WANG, Yueneng WANG, Boming CHENG, Yue YANG, Neng YE

“…Code domain non-orthogonal multiple access (NOMA) is one of the potential technologies to realize ubiquitous access in the future satellite internet.Considering that satellite-to-ground transmission has the characteristics of large propagation delay and high channel dynamics, strict timing synchronization between ground devices will lead to unbearable time resource overhead.Loosed synchronization relationship are required to achieve multi-user access in satellite internet.However, most of the existing multi-user detection algorithms in code domain NOMA are based on the assumption of synchronous transmission, which cannot accurately model and eff ectively alleviate the complex interference introduced by asynchronous multi-user transmission.Therefore, a novel multi-layer factor graph model by introduced the relative delay among users into the traditional two-part factor graph was constructed, and a low-complexity asynchronous multi-user detection algorithm based on gaussian approximation was proposed.The proposed algorithm iterated between each user's estimates and propagated the estimated information between users to improved the approximation.Simulation results showed that in high SNR region, the performance of the asynchronous code-domain NOMA with the proposed algorithm even outperforms its synchronous counterpart.…”

Ecological Sensitivity Analysis of Beihai City Based on GIS and RS by LI Xiaorong, XIE Yuting, LIU Ping

“…In this paper,five factors influencing ecological sensitivity were selected by using GIS and RS technologies,including land use/cover change (LUCC),normalized difference vegetation index (NDVI),elevation,aspect,and water buffer in land area of Beihai City,and the ecological sensitivity evaluation of single factor in the study area was carried out by using the ecological factor scoring method.The weighted superposition method was used to comprehensively evaluate the ecological sensitivity,and the study area was divided into the non-sensitive area,slightly sensitive area,moderately sensitive area,and highly sensitive area.The results show that the ecological sensitivity of the study area decreases from east to west and from north to south.The sum of the non-sensitive area and the slightly sensitive area is 64.30%,and the two areas are mainly distributed in the southwest,with an elevation below 30 m and relatively underdeveloped river networks.The moderately sensitive area accounts for 29.88% and is mainly distributed in Hepu County;the highly sensitive area accounts for 5.82% and is mainly distributed in the northeast mountainous area.The research results can provide a theoretical basis for ecological environment protection,green development,and rational land use planning in Beihai City.…”
