Survey on Giant Constellation Cloud Network Integration by Dan ZHANG, Jingjing LI, Tian LIU, Sunjie TAO, Ziping LYU

“…Thanks to the development of aerospace technology and the rise of concepts such as cloud computing and edge computing, cloud network convergence networks based on giant constellations are expected to become an important part of the integrated construction of star-ground and 6G global communication networks.Unlike terrestrial communication networks, constellation network topology is highly dynamic and time-varying, with strong resource and link heterogeneity, and other characteristics that pose challenges for cloud network convergence.The characteristics of giant constellations and the development status of terrestrial cloud network convergence was summarized, the urgent needs and challenges of cloud network convergence in giant constellations were analyzed, and the innovation of satellite internet cloud network convergence architecture, the use of resource virtualization technology, information sensing and routing path planning based on artificial intelligence algorithms, and cloud computing and edge collaborative computing were potential directions for future satellite-based cloud network convergence technology development direction were further pointed out.…”

EBS-based efficient and secure group key management in wireless sensor networks by WANG Wei1, ZHAO Wen-hong2, LI Feng-hua3.4, MA Jian-feng3

“…To achieve the secure group communication in wireless sensor networks（WSN）, a EBS-based group key management scheme was presented.First, the network topology was simplified by combining the chain-clusters and the star-clusters.Next, to prevent the adversary uncover all the administrative keys by a few colluding sensors, the number of sensors needed to capture WSN was increased.Then, the sensors of key combinations distribution were sorted through a coloring algorithm.Based on all these operations, the presented scheme distributed the administrative keys based on the hamming distance and EBS.Furthermore, the approaches handling the join event and leave event were described.Two experiments were performed to study the potential for collusions and the influence of size of compromised nodes on the effectiveness against collusions.Simulation results demonstrate that the presented scheme boosts the WSN’ resilience to attacks.The performance evaluation on join event and leave event shows that the number of key-updating messages and storage of sensors in the proposed scheme are fewer than those of SHELL.…”

Gamma-Ray Bursts as Multienergy Neutrino Sources by Katsuaki Asano, Kohta Murase

“…We also emphasize the importance of searches for GeV-TeV neutrinos, which are expected in the precursor/orphan or prompt phase, and lower-energy neutrinos would be more guaranteed and their detections even allow us to probe physics inside a progenitor star. Not only classical GRBs but also low-power GRBs and transrelativistic supernovae can be promising sources of TeV-PeV neutrinos, and we briefly discuss implications for the cumulative neutrino background discovered by IceCube.…”
