Achieving resist against DHCP man-in-the-middle attack scheme based on key agreement by Zhiqiang YAO, Zhirong ZHU, Guohua YE

“…In order to deal with the issue of the man-in-the-middle attack in the process of using dynamic host configuration protocol, a lightweight scheme was proposed.A new key agreement algorithm was developed based on public key cryptography to generate relevant keys, reducing the key storage burden.On the basis, a secure scheme was proposed, where two-way authentication of participants was designed to prevent the man-in-the-middle attack and digital signatures conforming to protocol specifications was constructed to ensure the legitimacy of the message source.By security analysis, the proposed scheme was demonstrated to be secure and valid against the man-in-the-middle attack and other common attacks.Experimental results show that the proposed scheme has the better performance compared with the related schemes, and can be compatible with both DHCPv4 and DHCPv6.…”

PM2.5 concentration prediction model based on random forest regression analysis by Xu DU, Jingyu FENG, Shaoqing LV, Wei SHI

“…The random foreat regression algorithm was introduced to solve the shortcomings of neural network in predicting the PM2.5 concentration,such as over-fitting,complex network structure,low learning efficiency.A novel PM2.5 concentration prediction model named RFRP was designed by analyzing the 22 characteristic factors including the meteorological conditions,the concentration of air pollutants and the season.The historical meteorological data of Xi’an in 2013—2016 were collected to verify the effectiveness of the model.The experimental results show that the proposed model can not only predict the PM2.5 concentration effectively,but also improve the operating efficiency of the model without affecting the prediction accuracy.The average run time of the proposed model is 0.281 s,which is about 5.58% of the neural network prediction model.…”

Architecture and practice of BGP internet routing visibility and security detection by Chaoyang YE, Chen SHEN, Mingqing HUANG, Shicong ZHANG, Yisha LIU

“…Border Gateway Protocol (BGP) is the de facto inter-domain routing protocol of today’s global internet for exchanging routing information.However, it was supposed that all participants were reliable without generating routing security issues by mistakes or on purpose when BGP was designed 50 years ago.As Internet is getting involved in all aspects of our society, internet routing security is becoming the problems that couldn’t be ignored anymore.A general architecture was proposed which coved inference of BGP routing knowledge database and provided visibility of global internet routing.Detection of route security events such as routing hijacks and routing leaks were realized.The deployment shows that the system can provide good visibility of internet routing and precise detection of routing security events.…”

Analysis of the throughput in full-duplex WLAN by Chen ZHAO, Yunzhou LI, Xibin XU, ANGJing W

“…WLAN is one of the important ways of accessing mobile internet.However，the performance of WLAN declines rapidly as the number of users increases.Improving the performance of WLAN with high density deployment is an important research direction of WLAN technology.Distributed coordination function（DCF）which was the basic media access method of IEEE 802.11 in infrastructure-based networks was modeled and the bottleneck of downlink throughput was pointed out.Taking advantage of full-duplex technology where there was a breakthrough in recent years，a new MAC protocol was designed and analyzed.By providing the AP full-duplex transmitting ability and simple modifications to traditional DCF protocol，the new protocol made the downlink throughput breaking through the bottleneck in infrastructure-based WLAN and increased the total throughput by more than 60%.…”

Research on secret key generation based on wireless channel characteristics in body area network by Jingjing HUANG

“…Wireless body area network (WBAN) is a human-centered wireless network.With limitations of power and computation capabilities of WBAN, the significant challenge of ensuring security is how to generate a shared key between two entities based on a lightweight symmetric cryptography.To investigate this issue, a secret key generation scheme in ultra-wideband (UWB) WBAN was designed.In this scheme, the difference of multipath relative delay and its average value were chosen as common random source to reduce key mismatch probability.Furthermore, with the aid of relay, secret key generation rate could be increased.Simulation and test results demonstrate that the proposed scheme can achieve a good tradeoff between key match probability and key generation rate.Furthermore, security analysis of the scheme was also provided to validate its feasibility.…”

Estimation scheme for parameters of wireless channel model in OFDM communication systems by WANG Yong, GE Jian-hua, WU Xiao-li

“…The conventional channel estimator in OFDM system was designed to cope with the worst-case channel condi-tion,thus performance degradation can be induced due to the imperfect channel estimation.Though wiener filter based on the minimum mean-squared error（MMSE） is the optimal linear estimator,it requires the prior information of transmis-sion channel.In order to select the near optimal prestored channel interpolation filter coefficients,three channel parame-ters detecting methods including maximum multipath delay,Doppler frequency and SNR based on the time and fre-quency correlation functions of the channel,the Euclidean distance of hard-decision in pilots position respectively,were proposed.The method proposed with low complexity allows an efficient implementation for adaptive channel estimation algorithm as well as multi-user OFDM systems.…”

Efficient and privacy-preserving profile matching protocols in opportunistic networks by Yong-kai LI, Shu-bo LIU, Zhao-huan YANG, Meng-jun LIU

“…In opportunistic networks,users can take the advantage of parallel opportunistic contacts with other mobile users and find the appropriate helpers to forward the messages or share the contents.Most of the existing profile-matching protocols were designed on the basis of homomorphic cryptosystem and were not quite efficient in encryption and decryption.Three efficient and privacy-preserving profile matching protocols were proposed to deal with different privacy requirements in opportunistic networks,which do not use any homomorphic encryption.The proposed protocols were proved to be privacy-preserving and correct.The performances of the protocols are thoroughly analyzed and evaluated via real smartphone experiments,and the results show that the proposed protocols can decrease encryption and decryption time by at least an order of magnitude than the Paillier cryptosystem based protocol.…”

Security mechanism in access control based on non-cooperative game by Yi-xuan ZHANG, Jing-sha HE, Bin ZHAO

“…Access control technology is an important information security technology to protect the sensitive information and critical resources in computer system and network.But traditional access control methods could only respond to access requests of users passively and can’t meet the changing dynamic network environment.In order to improve the ability to respond to malicious attacks and threats in access control system,a security mechanism is designed,which is suitable for access control,based on non-cooperative game theory in the game.When the subject makes an access request to the object,there will be a non-cooperative game between them to get Nash equilibrium.Then the security mechanism will compare the probabilities in the Nash equilibrium to the setting thresholds to get the conclusion that whether to authorize the subject or not.Experiment proves the effectiveness of the security mechanisms.…”
