Method for detecting collusion attack node in road condition information sharing based on reputation point by Shichang XUAN, Hao TANG, Wu YANG

“…Aiming at the problem that on occasion of the release of false road condition information by collusion nodes in the Internet of vehicles collaboratively, message authenticity could not be guaranteed in the process of road condition information sharing, a method for detecting collusion attack nodes in road condition information sharing based on reputation points was proposed.In the process of road condition information aggregation, a malicious information detection algorithm was designed to detect false messages issued by colluding nodes, which could ensure the authenticity and accuracy of messages delivered in the system.Experimental results show that the proposed method has higher detection efficiency for collusion nodes and adaption to a proportion of collusion nodes through security evaluation and experiments in comparison with the existing schemes.…”

Novel and effective secret sharing scheme by Run-hua SHI, Liu-sheng HUANG, Wei YANG, Hong ZHONG

“…A novel secret sharing scheme was proposed.This scheme consisted of two layer protocols:in the first layer,a larger secret was split into t smaller integers (sub-secrets) based on the Stern-Brocot tree; in the lower layer,t sub-secrets obtained from the first layer were regarded as t initial states in one-dimensional cellular automaton model,and then from the t initial states it could dynamic create all participants’ shares according to the simple fixed rule.This scheme could dynamic add new member,adjust the threshold value and renew the secret and the shares.Besides,there were still other advantages that the costs of the computation were very low and the size of the shares was very small.The results of analysis show that it was secure and very efficient.…”

Some key technical issues in the evolution from cloud network to computing network by Chang CAO, Shuai ZHANG, Ying LIU, Xiongyan TANG

“…Firstly, the development trend of cloud-network integration technology in recent years, the new problems and challenges it faces were analyzed.Then, based on the heterogeneous computing power, the sinking of computing power, and the new changes in computing-network linkage in business development, six major computing and network capabilities were proposed.Convergence requirements, combined with multi-cloud connection, differentiated bearer, and hierarchical security, discussed the case of building new capabilities and new business experience around the computing network.The analysis results show that it can be concluded that the computing network and the cloud network are closely related in the technical system, and the integration of the computing network is the inevitable result of the development and evolution of the integration of the cloud and the network, and it is also an inevitable choice for the development of the digital economy.…”

Measuring and analyzing node families in the Tor anonymous communication network by Xiao WANG, Bin-xing FANG, Pei-peng LIU, Li2 GUO, Jin-qiao SHI

“…Tor family was focused on design and given a family-level measurement of it.Based on Tor node families (over 3000) discovered from live Tor network data (from Jan.2011 to Dec.2012),a few characteristics of Tor node families were revealed,such as family size,bandwidth,geographical distribution as well as operators providing a few big families.The analysis validated the irreplaceable role played by family design in enhancing Tor’s anonymity.Based on the measurement,security analysis showed the serious availability threat a compromised node family can cause to the Tor network.Besides,It also discussed Tor hidden families and the potential anonymity risk caused by them.…”

Carrier-grade NTP clock synchronization scheme of SD-WAN network by Qiangen ZHAO, Yu WANG, Ling TANG, Yongming YAN

“…SD-WAN is developing rapidly, and telecom operators and Internet companies are constantly expanding their layout.As a technology with diverse forms, SD-WAN has not made a clear specification for clock synchronization.The importance of clock synchronization to SD-WAN technology implementation and business running was analyzed.The advantages and disadvantages of the clock synchronization scheme of Internet public NTP service widely used in SD-WAN realizations were sketched.Thus the clock synchronization scheme of self-built NTP service in different scenarios was discussed.Furthermore, a clock synchronization method using management tunnel to transmit encrypted NTP synchronization data was designed, which made SD-WAN platform and devices obtain higher security and stability in time synchronization.…”

Research and implementation of reconfigurable SM4 cryptographic algorithm based on HRCA by Xiao ZHANG, Qinglei ZHOU, Bin LI

“…For the application scenarios that require high throughput and high security at the same time,based on HRCA,a high-performance scalable SM4 implementation scheme was proposed.Firstly,SM4 was formed to different calculation units of different granularity,and a general coarse-grained reconfigurable calculation unit was designed.Then,various mapping strategies were given for the purpose of satisfying different encryption modes,and the algorithm was mapped to the reconstructed computing unit according to different strategies.Finally,the SM4 overall architecture was optimized by dividing the control plane and the data plane.The experimental results show that using the proposed method,the SM4 algorithm has a significant improvement in throughput under lower resource consumption.…”

Privacy protection key distribution protocol for edge computing by Jian SHEN, Tianqi ZHOU, Chen WANG, Huijie YANG

“…Aiming at the privacy protection problem in the multi-application scenarios of edge computing, two policy-based key distribution protocols were proposed.The proposed protocols are based on the concept of constrained pseudo-random functions to achieve efficient and flexible policy selection.Specifically, based on the GGM pseudo-random number generator, the key distribution protocol with a prefix-predicate is constructed, which can effectively support lightweight and efficient key distribution.Moreover, based on the multilinear pairing, the key distribution protocol with a bit fixing predicate is constructed.This protocol can support flexible and fine-grained strategy selection and is suitable for dynamic and flexible multi-device scenarios in heterogeneous networks.Finally, the security proof of the proposed protocols is presented.…”
