In this paper, we first give a new set of design goals for anonymous two-factor authentication scheme. The new set is a refinement of some previously proposed requirement sets;it not only eliminates the redundancies, conflicts and ambiguities of the old ones, but also provides more desired security properties. Then we demonstrate that both of Sun et al.'s scheme and Li et al.'s scheme fail to satisfy all the security goals we propose. Specifically, we point out that Sun et al.'s scheme still suffers from the smart card loss problem and fails to provide user untraceability. Li et al.'s scheme is vulnerable to desynchronization attack. In order to remedy these defects in their schemes, we propose a robust two-factor authentication and key agreement scheme with user privacy preservation achieving all the goals we present. Compared with the previous schemes, our scheme not only provides more security guarantees, but also is still efficient both in computation and communication cost.

Multi-threaded programs play an increasingly important role in current multi-core environments. Exposing concurrency bugs and debugging such multi-threaded programs have become quite challenging due to their inherent non-determinism. In order to eliminate such non-determinism, many approaches such as record-and-replay and other similar bug reproducing systems have been proposed. However, those approaches often suffer significant performance degradation because they require a large amount of recorded information and/or long analysis and replay time. In this paper, we propose an effective approach, ReCBuLC, to take advantage of the hardware clocks available on modern processors. The key idea is to reduce the recording overhead and analyzing events' global order by using time stamps recorded in each thread. Those timestamps are used to determine the global orders of shared accesses. To avoid the large overhead incurred in accessing system-wide global clock, we opt to use local per-core clocks that incur much less access overhead. We then propose techniques to resolve differences among local clocks and obtain an accurate global event order. By using per-core clocks, state-of-the-art bug reproducing systems such as PRES and CLAP can reduce the recording overheads by 1% ~ 85%, and the analysis time by 84.66% ~ 99.99%, respectively.

Research on a denoising smoothing algorithm for 3D scattered point cloud

引用

ICIC Express Letters 2014年第9期8卷 2403-2409页

作者： Gu, Xiaoying Liu, Yongshan Wu, Qiong Department of Information Science and Engineering China The Key Laboratory for Computer Virtual Technology and System Integration of Hebei Province Yanshan University No. 438 Hebei Ave. Qinhuangdao 066004 China Data Industry Research Lab Qinhuangdao 066004 China

In order to effectively eliminate outliers and noise points in 3D scattered point cloud, a denoising smoothing algorithm which is the combination of removing outliers algorithm and trilateral filter is proposed. This is accomplished by rejecting outliers, correcting the normal direction and moving noise points along the modified normal direction within local adaptive neighborhoods. First, the outliers are removed by the method of mathematical statistics, on this basis, estimating normal direction and curvature of point cloud by covariance analysis method. Then, correct the normal direction by combining trilateral filter weighting factor with adaptive optimal neighborhood function. Finally, calculate position offset of data points in the direction of normal amendment by trilateral filter weighting factor in order to smooth the point cloud. Experimental results show that the proposed method is simple and effective, successfully removing noise from point cloud while preserving inherent geometric features. © 2014 ISSN 1881-803X.

Effect of source tampering in the security of quantum cryptography

The security of source has become an increasingly important issue in quantum cryptography. Based on the framework of measurement-device-independent quantum key distribution (MDI-QKD), the source becomes the only region exploitable by a potential eavesdropper (Eve). Phase randomization is a cornerstone assumption in most discrete-variable (DV) quantum communication protocols (e.g., QKD, quantum coin tossing, weak-coherent-state blind quantum computing, and so on), and the violation of such an assumption is thus fatal to the security of those protocols. In this paper, we show a simple quantum hacking strategy, with commercial and homemade pulsed lasers, by Eve that allows her to actively tamper with the source and violate such an assumption, without leaving a trace afterwards. Furthermore, our attack may also be valid for continuous-variable (CV) QKD, which is another main class of QKD protocol, since, excepting the phase random assumption, other parameters (e.g., intensity) could also be changed, which directly determine the security of CV-QKD.

Radio Frequency IDentification (RFID) is a radio communication technique. It identifies specific targets and acquires related data from the backend database by using radio frequency signal and no physical touch needed. Because of its advantages of low cost and remote identity-recognition, this technology has been widely used in many applications. However, the information, which is transmitted via radio signal, is easily eavesdropped and traced by an attacker. Therefore, it is important to design a secure RFID protocol which can ensure the authentication of the origin and the integrity of the transmitted information. Researchers have put their efforts into this field and proposed many solutions to deal with these issues. In particular, in 2012, Bassil et al. introduced an ultra-lightweight RFID protocol based on a physical unclonable function (PUF), which means that the tags in the RFID architecture are unclonable. However, the insecurity of the scheme has been pointed out recently. In this paper, we will propose a new ultra-lightweight RFID protocol based on PUF that can overcome the security loopholes occurs in Bassil et al.'s protocol. © 2014 The authors and IOS Press.

Jet energy scale measurements and their systematic uncertainties are reported for jets measured with the ATLAS detector using proton-proton collision data with a center-of-mass energy of s=13 TeV, corresponding to an integrated luminosity of 3.2 fb−1 collected during 2015 at the LHC. Jets are reconstructed from energy deposits forming topological clusters of calorimeter cells, using the anti-kt algorithm with radius parameter R=0.4. Jets are calibrated with a series of simulation-based corrections and in situ techniques. In situ techniques exploit the transverse momentum balance between a jet and a reference object such as a photon, Z boson, or multijet system for jets with 200.8) is derived from dijet pT balance measurements. For jets of pT=80 GeV, the additional uncertainty for the forward jet calibration reaches its largest value of about 2% in the range |η|>3.5 and in a narrow slice of 2.2<|η|<2.4.

New identity-based key-encapsulation mechanism and its applications in cloud computing

Identity-based encryption (IBE) is an important primitive of identity-based cryptography. As such, it is a type of public-key encryption in which the public key of a user is some unique information about the identity of the user (e.g., a user's e-mail address). As a special form of IBE, identity-based key encapsulation mechanism (IB-KEM) can be used to create a random session key for encrypting messages. Any IB-KEM can be updated to a full IBE scheme by adding a symmetric encryption scheme with appropriate security properties. Currently, IB-KEM is a fundamental primitive of cryptography, and can be used to protect information system security, network security, cloud security, etc. In this paper, we construct a new IB-KEM in a generic levelled multilinear map setting and prove its security under multilinear decisional Diffie-Hellman assumption in the selective-ID model. Then, we make our IB-KEM translated to the GGH framework, which is proposed by Garg et al. (2013a). This framework defines an approximate version of a multilinear group family from ideal lattices. Finally, as an application of our new scheme, we introduce how to achieve secure transmission in the hierarchical architecture for cloud computing (HACC).

Legged robots have better performance on discontinuous terrain than that of wheeled robots. However, the dynamic trotting and balance control of a quadruped robot is still a challenging problem, especially when the robot has multi-joint legs. This paper presents a three-dimensional model of a quadruped robot which has 6 Degrees of Freedom （DOF） on torso and 5 DOF on each leg. On the basis of the Spring-Loaded Inverted Pendulum （SLIP） model, body control algorithm is discussed in the first place to figure out how legs work in 3D trotting. Then, motivated by the principle of joint function separation and introducing certain biological characteristics, two joint coordination approaches are developed to produce the trot and provide balance. The robot reaches the highest speed of 2.0 m.s-1, and keeps balance under 250 Kg.m.s-1 lateral disturbance in the simulations. The effectiveness of these approaches is also verified on a prototype robot which runs to 0.83 m.s-1 on the treadmill, The simulations and experiments show that legged robots have good biological properties, such as the ground reaction force, and spring-like leg behavior.

Applying system Thinking to Learn from Accident of Modern Automatic Control systems

Chinese Journal of Electronics 2014年第2期23卷 409-414页

Modern societies increasingly rely on automatic control systems. These systems are hardly pure technical systems; instead they are complex socio-technical systems, which consist of technical elements and social components. It is necessary to have a systematic approach to analyze these systems because it is growing evidence that accidents from these systems usually have complex causal factors which form an interconnected network of events,rather than a simple cause-effect chain. We take railway Train control systems(TCS) as an example to demonstrate the importance of the socio-technical approach to analyze the system. The paper presents an investigation of recent high-speed railway accident by applying STAMP – one of the most notable socio-technical system analysis techniques, outlines improvements to the system which could avoid similar accidents in the future. We also provide our valuable feedback for the use of STAMP.

A search is presented for anomalous quartic gauge boson couplings in vector-boson scattering. The data for the analysis correspond to 20.2 fb−1 of s=8 TeV pp collisions and were collected in 2012 by the ATLAS experiment at the Large Hadron Collider. The search looks for the production of WW or WZ boson pairs accompanied by a high-mass dijet system, with one W decaying leptonically and a W or Z decaying hadronically. The hadronically decaying W/Z is reconstructed as either two small-radius jets or one large-radius jet using jet substructure techniques. Constraints on the anomalous quartic gauge boson coupling parameters α4 and α5 are set by fitting the transverse mass of the diboson system, and the resulting 95% confidence intervals are −0.024<α4<0.030 and −0.028<α5<0.033.
