The laser interferometric gravitational wave detection in space is an important and realistic approach to studying some key problems of astronomy and cosmology, such as the stellar evolution and galactic formation in the early universe, the co-evolution of black holes and galaxies, etc. After performing two stages of the Advance Research Project of Space Science commissioned by the Chinese Academy of Sciences, and by weighing the feasibility of technology and the foresight of science, we have selected the gravitational wave sources including the high-redshift intermediate-and-large mass binary black hole mergers, and the intermediate-mass black holes in clusters and other dense dynamic environments, as the main scientific objectives, and given a preliminary design for the project of Chinese space gravitational wave detection in the frequency range from millihertz to hertz. Based on this, here we introduce briefly the science of the space gravitational wave detection, as a new measure of astronomical observations, as well as the scientific objectives and potential detectivity of the design for the Chinese space gravitational wave detection mission.

Adaptability of BFS algorithm and multicore processor

Dongbei Daxue Xuebao/Journal of Northeastern University 2014年 35卷 96-101页

The typical features of graph algorithm represented by breadth-first search (BFS) were investigated, and a lightweight heuristic switch strategy was designed and implemented by automatically switching through two basic search methods to improve search efficiency. Based on discrete and random data access characteristics of BFS algorithm and execution mechanism of multicore processor, an analytic model of multicore processor architecture was established to guide the research about the operating characteristics and performance trends on the typical multicore processors. The results showed that the lowest Cache hit ratio is about 85%, pipeline stall ratio is more than 50%, branch misprediction ratio reaches up to 14%, and pipeline total utilization efficiency is only 35%. So the current multicore processor can't support graph computing efficiently. ©, 2014, Northeastern University. All right reserved.

This Letter presents a search for new resonances with mass larger than 250 GeV, decaying to a Z boson and a photon. The dataset consists of an integrated luminosity of 3.2 fb⁻¹ of pp collisions collected at s=13 TeV with the ATLAS detector at the Large Hadron Collider. The Z bosons are identified through their decays either to charged, light, lepton pairs (e⁺e⁻, μ⁺μ⁻) or to hadrons. The data are found to be consistent with the expected background in the whole mass range investigated and upper limits are set on the production cross section times decay branching ratio to Zγ of a narrow scalar boson with mass between 250 GeV and 2.75 TeV. © 2016 The Author(s)

G Bytes Data Hiding Method Based on Cluster Chain Structure

引用

Wuhan University Journal of Natural Sciences 2013年第5期18卷 443-448页

作者： NIU Xiaopeng LI Qingbao WANG Wei WANG Yulong State Key Laboratory of Mathematical Engineering and Advanced Computing PLA Information Engineering University

Protecting the security of sensitive information has become a matter of great concern to everyone. Data hiding technique solves the problem to some extent, but still, some shortcomings remain for researching. To improve the capability of hiding huge data file in disk with high efficiency. In this paper, we propose a novel approach called CryptFS, which is achieved by utilizing the file access mechanism and modifying the cluster chain structure to hide data. CryptFS can quickly hide data file with G bytes size in less than 0.1s. The time used for hiding and recovering data is irrelevant to the size of data file, and the reliability of the hidden file is high, which will not be overlaid by new created file and disk defragment.

In this paper, we introduce a class of cubic rotation symmetric (RotS) functions and prove that it can yield bent and semi-bent functions. To the best of our knowledge, this is the second primary construction of an infinite class of nonquadratic RotS bent functions which could be found and the first class of nonquadratic RotS semi-bent functions. We also study a class of idempotents (giving RotS functions through the choice of a normal basis of GF(2n) over GF(2)). We derive a characterization of the bent functions among these idempotents and we relate their precise determination to a problem studied in the framework of APN functions. Incidentally, the proofs of bentness given here are useful for a paper studying a construction of idempotents from RotS functions, entitled "A secondary construction and a transformation on rotation symmetric functions, and their action on bent and semi-bent functions" by the same authors, to appear in the journal JCT series A. © Springer International Publishing Switzerland 2014.

Traditional multicast protocol forms multicast trees rooted at different sources to forward packets. If the multicast sources and receivers are in different domains, these trees will produce a great number of multicast states in the backbone, resulting in poor scalability. Therefore, we propose a one Wide-Sense Circuit Tree per Traffic Class based inter-domain multicast (WSCT-TC), in which a Wide-Sense Circuit Tree (WSCT) is established for a class of multicast traffic. The WSCT is established in the backbone, along which multicast packets are forwarded by label switching. The spec of WSCT can be reconfigured according to the QoS (Quality of Service) requirement of multicast applications, to provide preferable QoS. Simulating experiment shows that WSCT-TC behaves better scalability. © 2013 IEEE.

The design of secure password authenticated key exchange (PAKE) protocols with RSA is a nontrivial hard work. Until now there have been only a few secure PAKE protocols based on RSA and most of them work in the two-party setting. Although two-party PAKE protocols are quite useful for client-server architectures, they are very inconvenient in key management for client-client communications in large-scale communication environment. In this paper we present an efficient PAKE protocol using RSA in the three-party setting, called E3PAKE-RSA protocol. We also provide a formal security proof of E3PAKE-RSA protocol under the RSA assumption and the random oracle model. © 2013 IEEE.

IP multicast suffers from scalability and QoS provisioning problems when supporting large scale group communication cross domain. To solve the problems, we propose WSCT-PAN, a per-access-network based wide-sense circuit tree transmission scheme, in which one Wide-Sense Circuit Tree (WSCT) is established for a class of multicast traffic per access network. By using mapping and label switching, multiple multicast groups' traffic with the same traffic class from the same access network share only one dynamic reconfigurable wide-sense circuit tree in the backbone network. The WSCT branches extend only to the access networks the multicast receivers located in. So, the tradeoff between efficient multicast label switching and traffic redundancy in the backbone network is achieved. Compared with the traditional cross domain multicast, WSCT-PAN is more scalability, and suitable for large scale cross domain multicast deployment. © 2013 IEEE.

DDoS attack and defense is regarded as a multistage signaling game with observable actions. Its extensive form is given out, and its perfect bayesian nash equilibrium is solved. The current problems encountered by DDoS attack defense are discussed. Theoretical analysis proves the feasibility and effectiveness of the service hopping strategy. This paper draws a conclusion that adding service hopping strategy is superior to a pure filtering strategy, also provides beneficial reference on DDoS attack prevention. © 2013 IEEE.
