Rapid responsive and efficient multi-valued Byzantine consensus scheme by Wang ZHOU, Honggang HU, Nenghai YU

“…Due to the increase of network equipments and the uncertainty of the transmission environment, the message delay is also uncertain, and the asynchronous consensus protocol possesses more advantages.Miller et al proposed the first asynchronous consensus protocol HoneyBadgerBFT in 2016, but its transmission efficiency can be optimized furthermore while achieving high throughput.The broadcast protocol in HoneyBadgerBFT was improved by reducing the message complexity in the broadcast process, and adding optional message request process to achieve rapid response and efficient transmission.…”

Research on IPv6+ intelligent backbone network technology by Jianguo LIU, Hao QU, Hongming HUANG, Zhidan ZHU

“…The China Media Group backbone network is a key infrastructure that connects the headquarters, data centers, hubs/journalists at home and abroad, and “hundreds cities and thousands of screens” across the country, and IPv6+ is the main technical route of the next-generation IP network.The present situation and challenges of the backbone network of the headquarters were mainly analyzed, the principle, advantages and technical characteristics of the core of IPv6+ were introduced, and how IPv6+ technology adapts to the development of broadcast and television services was discussed.Finally, the conception and suggestion of constructing and deploying the next generation broadcast TV backbone network based on IPv6+ were put forward.It provided a new idea to simplify the protocol and speed up the service opening for the future construction of backbone network of radio and television stations.…”

An energy balance AODV protocol with multicast route discovery for wireless body area networks by Jin TAN, Yujuan ZHANG

“…In AODV protocol with the dynamic topology networks，the source node S requests a route to an arbitrary destination node D with flooding broadcast the RREQ message，but there is only one destination node sink in a WBAN，other nodes involved in receiving and forwarding RREQ have wasted energy except the nodes on minimum hop count routing.An energy balance AODV protocol with multicast route discovery for wireless body area networks was proposed，it increased the minimum hop count to sink hops，the next hop node to sink next and the node itself has the forwarding capability isforward three parameters in a hello message，and selects neighbors which could reach the sink only to participate in forwarding the RREQ message.This protocol effectively reduces the energy cost of the routing discovery through changing the broadcast to multicast，and prolongs the service life of WBAN with energy balance.The performance analysis and simulation experiment indicate that the proposed protocol is more advantaged than similar EAAODV in the number of RREQ，packet delivery ratio and energy consumption.…”

PKI cross-domain authentication scheme based on advanced PBFT algorithm by Sijie QIAN, Liquan CHEN, Shihui WANG

“…In order to solve the efficiency problem of the existing public key infrastructure cross-domain authentication scheme,a cross-domain authentication model based on the consortium blockchain which has the advantages of distributed and difficult to be tamperd with was proposed.On the one hand,the dynamic join and exit function was added to the practical Byzantine fault tolerant (PBFT) algorithm,the primary node election mode was improved,and the three-stage broadcast was reduced to two-stage broadcast for the reducation of communication overhead.On the other hand,the cross-domain authentication system architecture based on consortium chain was designed,the blockchain certificate format and the cross-domain authentication protocol were presented,the security and efficiency were analyzed.The results shows that in term of security,the proposed model has security attributes such as resisting distributed attacks.In terms of performance,the proposed model has advantages in both computational overhead and communication overhead when it was compared with the existing cross-domain authentication schemes.…”

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.…”

Bus cache-based location privacy protection scheme in the Internet of vehicles by Jie CUI, Xuefeng CHEN, Jing ZHANG, Lu WEI, Hong ZHONG

“…To solve the problem of real location leakage when vehicles use location-based service (LBS) on the Internet of vehicles, a location privacy protection scheme based on bus cache was proposed.Firstly, a point of interest (POI) pool was obtained from the LBS provider based on its route information.Then the data in the POI pool was selected form a POI list while driving.Finally, the POI list was broadcast to surrounding private vehicles.After the private vehicle received the broadcast data, it verified the identity of the bus and then stored the POI list in the vehicle’s local cache.When a private vehicle needed to query POI information, it would first retrieve it in the local cache, and if the cache was missed, it would send a query request to the LBS provider using the k-anonymity method.The simulation experiment results show that the proposed scheme can reduce the possibility of leakage of the real location of the private vehicle by reducing the number of communications between the private vehicle and the LBSP, thereby effectively improving the privacy protection level of the private vehicle.…”
