On-demand key management based on social attribute for opportunistic networks by Xi CHEN, Guang-song LI, You-liang TIAN, Jian-feng MA

“…An on-demand key management scheme was proposed based on social attributes,which could conform to the characteristics of intermittent connectivity,high mobility and self-organized management in opportunistic networks.By utilizing the identity-based threshold signature scheme,the authentication of nodes’social attributes was realized.Due to the specialty of the opportunistic routing protocols,nodes selectiv ly issued the identity certificates for each other to establish the Web of trust based on the matching of social attributes.Consequently,the performance of certificate graph was efficiently optimized comparing to the traditional met .Meanwhile,thanks to checking the social attribute evidences,the invalid certificate chains caused by malicious nodes were avoid to be built.Simulation result shows that,the scheme can provide high success ratio for reconstruction of certificate chains and high user reachability through low network costs in opportunistic networks.…”

Spatio-temporal aware privacy-preserving scheme in LBS by Weihao LI, Sheng DING, Jiajie MENG, Hui LI

“…Location-based service (LBS) brings a lot of conveniences in people’s daily life,but the conveniences are accompanied with the leaking of privacy.A dummy-based location-preserving scheme was proposed,which took the correlation between spatial issues and temporal issues into account.Two algorithms were included in this scheme,map dividing algorithm and dummy contents determining algorithm.The map dividing algorithm divided the map into discrete location cells by Voronoi Diagram to ensure these discrete location cells were not adjacent to each other.The dummy contents determining algorithm replaced the query content in previous moment by the intending location in next moment,which efficiently avoided the adversary inferring mobile users’ sensitive information according to the correlation between spatial issues and temporal issues.The simulation experiments show that the proposed scheme is effective and efficient.…”

Review on unmanned aerial vehicle covert communication network by Hengzhi BAI, Haichao WANG, Guoxin LI, Yuping GONG

“…Unmanned aerial vehicle (UAV) communication network is an important part of the future integrated space-aerial-ground network, and an effective support to achieve the global three-dimensional coverage of the communication network.The open characteristics of wireless channels make UAV communication vulnerable to malicious attacks by illegal users.Covert communication provides a promising solution for improving the security defense and privacy protection capabilities of UAV communication.However, the overlapping characteristics of the mobility of UAV systems and the requirements of covert communication scenarios bring severe challenges to the collaborative optimization of network resources.The UAV covert communication network was investigated from requirements, challenges, framework and main technologies perspectives.The architecture and model, performance characteristic, as well as potential candidate technologies were analyzed and discussed, in an attempt to outline the overall framework of UAV covert communication, and provide guidance for the subsequent research on UAV covert communication.…”

An incentive mechanism with bandwidth allocation for federated learning by Yingyun GUO, Bo GAO, Zhifei ZHANG, Yu ZHANG, Ke XIONG

“…Federated learning (FL) is an emerging machine learning paradigm that can make full use of crowd sourced mobile resources for training on decentralized data.However, it is challenging to deploy FL over a wireless network because of the limited bandwidth and clients’ selfishness.To address these challenges, an incentive mechanism with bandwidth allocation (IMBA) was proposed.Considering the difference between clients' data quality and computing power, IMBA designs a payment scheme to incentivize high-quality clients to contribute their computing resources, thus improving the training accuracy of the model.By minimizing the weight sum of training time and payment cost, the optimal payment and bandwidth allocation scheme was determined, and the training delay was reduced by optimizing bandwidth allocation.Experiments show that IMBA effectively improves training accuracy, reduces the training delay and helps the server flexibly balance training delay and hiring payment.…”
