Research on safety supervision data sharing of railway construction projects based on edge computing by Liang YANG, Chunhui PIAO, Yuhong LIU, Meimei JI

“…Information security monitoring system is widely used in railway construction projects,but the existing safety supervision model has problems such as high server load,heavy network bandwidth pressure,monitoring data can’t be effectively shared,key monitoring data may be tampered,and security accident responsibility is difficult to determine.A credible sharing model of safety supervision data for railway construction projects based on edge computing was proposed.On one hand,the construction of a safety monitoring edge computing framework for construction projects was constructed,and the data processing flow of edge nodes was described; on the other hand,a trusted data sharing framework based on blockchain was established,and a safety supervision data sharing process was designed and trusted sharing data was implemented through smart contracts.The proposed solution combined with edge computing and blockchain technology,which not only could strengthen the safety supervision of railway construction projects by industry authorities,but also provide new opportunities for stakeholders to share safety monitoring data in real time.…”

Dynamic switching based real-time routing in low-duty-cycle wireless sensor networks by Quan CHEN, Hong GAO

“…The dynamic switching based real-time(DSRT)routing protocol was proposed to handle the arbitrary end-to-end(E2E)real-time communication in the low-duty-cycle wireless sensor networks.Firstly,the concept of available speed was designed to compensate for the big sleep latency and facilitate discovering the routes with less latency based on two-hop neighbors’ information(at lease about 20% routing path with less latency was discovered by DRST in the experiments).Moreover,it was noticed that the congestion extent in the low-duty-cycle network was determined not only by the number of packets in the network output queue,but also the destination of the packets.However,the traditional method with one-hop neighbors’ information cannot differentiate this kind of congestion.Therefore,combined with the dynamic switching mechanism,the DSRT proposed a congestion avoiding algorithm by classifying the packets in the queue.Through comprehensive experiments,the efficiency of routing discovering and congestion avoiding of the DSRT protocol is demonstrated,and the E2E delay is decreased by at least 200% when the traffic was high.…”

Towards edge-collaborative, lightweight and privacy-preserving classification framework by Jinbo XIONG, Yongjie ZHOU, Renwan BI, Liang WAN, Youliang TIAN

“…Aiming at the problems of data leakage of perceptual image and computational inefficiency of privacy-preserving classification framework in edge-side computing environment, a lightweight and privacy-preserving classification framework (PPCF) was proposed to supports encryption feature extraction and classification, and achieve the goal of data transmission and computing security under the collaborative classification process of edge nodes.Firstly, a series of secure computing protocols were designed based on additive secret sharing.Furthermore, two non-collusive edge servers were used to perform secure convolution, secure batch normalization, secure activation, secure pooling and other deep neural network computing layers to realize PPCF.Theoretical and security analysis indicate that PPCF has excellent accuracy and proved to be security.Actual performance evaluation show that PPCF can achieve the same classification accuracy as plaintext environment.At the same time, compared with homomorphic encryption and multi-round iterative calculation schemes, PPCF has obvious advantages in terms of computational cost and communication overhead.…”

Game-theoretical analysis of mobile contributors in mobile crowd sourcing network with word of mouth mode by Feng ZENG, Runhua WANG, Jia PENG, Zhigang CHEN

“…The crowdsourcer who calls for sensing service can recruit enough mobile contributors quickly with the word of mouth mode,improving the quality of sensing tasks.The behavior of mobile contributors in mobile crowdsourcing with the WoM was investigated.It was supposed that each mobile contributor was rational,seeking for the highest utility.The behavior of mobile contributors with a two-level Stackelberg game was formulated.In the first-level game,a mobile contributor who directly worked for the crowdsourcer acted as the leader,while contributors invited by first-level contributors were followers called the second-level contributors.In the second-level game,the second-level contributors were the leaders and contributors invited by them were followers.The Nash equilibrium for each Stackelberg game was proved was existed and unique,and designed an algorithm to reach the equilibrium.Backward induction approach to compute the best response of each game was adopted,and the simulation results show the correctness of theoretical analysis for the interaction among contributors in crowdsoucing with WoM.…”

Coding-aware secure routing for multi-hop wireless networks by Xian GUO, Tao FENG, Zhan-ting YUAN

“…To address security issues of DCAR in“coding+routing”discovery,a new security destination was proposed and a distributed coding-aware secure routing(DCASR)was designed.DCASR guarantees discovery of correct coding opportunity and establishment of trusted routes by using cryptography.To analyze the properties of DCASR,LS2(logic of security systems)was extended,and a new logic LS2-RP(LS2 for routing protocol)was proposed.In LS2-RP,the concepts of location and neighboring location of thread were introduced.The dynamic topology of multi-hop wireless networks was described by the set of neighbors for thread.The broadcast rule of neighboring location threads modeled the feature of wireless broadcast communication.Finally,DCASR was described by programming language of LS2-RP and security properties were defined by predicates and modal formulas of LS2-RP.Security of DCASR was analyzed by using the proof system of LS2-RP.DCASR can satisfy our secure destination.…”
