Security analysis of public-key cryptosystems based on matrix action problem against quantum attack by Huawei HUANG

“…As a generalization of the discrete logarithm problem, semigroup action problem has important applications in the design of public-key cryptography.Public-key cryptosystems based on action problem of integer matrix semigroups on the direct product of commutative groups were analyzed.The matrix was regarded as the exponent of direct product elements, and this class of matrix action had the exponential rules similar to group.It was proved that if the matrix action was injective or the number of generators of the hidden subgroup was less than or equal to the square of the order of the matrix, the matrix action problem could be reduced in polynomial time to the hidden subgroup problem of the direct sum of the additive group of the matrices.And it was proved that commutative matrix action problem could also be reduced to hidden subgroup problem of the direct sum of the additive group of the matrices in polynomial time.The cryptosystems based on this class of matrix action problem cannot against quantum attacks.This conclusion has theoretical significance in the design of public-key cryptography against quantum attacks.…”

Research Progress of Treatment of Black and Odorous Water Bodies with Aeration Technology by WU Zuojingtong, DAI Xianpu, WU Hui, PAN Hongzhong

“…When treating black and odorous water bodies,the current aeration technology is faced with problems such as unscientific aeration design,unreasonable design of parameters such as aeration volume,aeration time,and influence radius,and unclear mechanism of coupling with other technologies.To solve these problems,this paper conducts a literature study of the effect of aeration in reducing common pollutants in water bodies and clarifies the effectiveness of aeration in the treatment of black and odorous water bodies.Then,factors affecting the aeration effect are comprehensively analyzed,and the following conclusions are drawn from the results.Bottom microbubble aeration has significant advantages in effect and energy consumption;clear correlations among aeration intensity,aeration time,and pollutant removal rate are observed;when energy consumption and effect are comprehensively considered,the room for optimization of aeration/non-aeration ratio remains large.Finally,an overview and prospects of the coupling study of aeration and other technologies are presented.This research is expected to provide a theoretical reference for the treatment of black and odorous water bodies with aeration technology.…”

Parallel orchestration and deployment system for scalable heterogeneous service function chain supporting polymorphic network by Hao CHEN, Yuan YANG, Mingwei XU, Dan PEI, Yilin YOU

“…Aiming at the problem of second-level service function chain orchestration and deployment in the polymorphic data center with the scale of 10 000 servers, a scalable heterogeneous SFC parallel orchestration and deployment (SHOD) system was proposed.The scale-out orchestration time of service chain was reduced to seconds by partitioning the data center and adopting a parallel orchestrator design that minimizes resource usage.Using a mediator design model that satisfies the single-responsibility principle, the heterogeneous equipment scalable orchestration and deployment were realized as well as service function chain building chain.Experimental results show that in a data center with 10 000 servers, the scale-out orchestration time of SHOD system is reduced to <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML"> <mfrac> <mn>1</mn> <mrow> <mn>12</mn></mrow> </mfrac> </math></inline-formula> of the existing system-Daisy, while only 1.5 times CPU utilization overhead is introduced.…”

Design Method of Crank-rocker Mechanism based on Maximum Value of Minimum Transmission Angle by Chen Haiwen, Wang Zhong, Zhao Fei

“…Under the conditions of giving the length of the rocker CD,swinging angle φ and advance-to return-time ratio K（extreme position angle θ）,in order to design crank-rocker mechanism with the maximum value of minimum transmission angle γmin,the supplementary angle β（be used to determine the position angle of the rotation center A of crank） is introduced,the function relation of minimum transmission angle γminand the supplementary angle β is established.Then the maximum value of minimum transmission angle γmincan be obtained by utilizing procedure of Matlab.At the same time,in view of the different K value,the mechanism of type selection is classified.Then,points out the typeⅠ and Ⅱmechanism can be used to design and typeⅠ mechanism is better in force-passing property when K ∈（1,3）.When K∈[3,+ ∞),if type Ⅱ mechanism is used to carry on the design,which will not be able to meet the requirement of the rocker swinging angle,if typeⅠ mechanism is used,which has low efficiency and is not conductive to transmission of the mechanism.…”

Survey on IPv6 address scanning technology based on seed sources by Guo LI, Lin HE, Guanglei SONG, Zhiliang WANG, Jiahai YANG, Zimu LI

“…Nowadays,the state-of-the-art technologies can spend a very short time to scan the whole IPv4 space,but these methods cannot be applied to the huge IPv6 space easily.Therefore,many researchers propose different heuristic algorithms for the sake of IPv6 scanning.The common way of these algorithms is to input collected IPv6 seed addresses and output new most likely active IPv6 addresses as candidates for later scanning.These methods greatly reduce the scanning range of the active address area.These technologies based on seed addresses were classified,analyzed and summarized,and detailed analysis of the advantages and disadvantages of each method was given.And the several challenges faced by the methods were discussed.73M seed addresses were collected in total from two sources,including published IPv6 datasets in papers and Beijing Node of China Education and Research Network.Through the proposed experiments,time performance and hit rate of four IPv6 address scanning technologies based on seed addresses was compared.Finally,the own thoughts on this field and some future research directions were proposed.…”
