Media independent information service is one of the important parts of the IEEE 802.21 standard to optimize vertical handover in wireless heterogeneous networks. In this paper, an anonymous network information acquirement protocol is proposed for a mobile user, which can be used to establish a secure channel between the mobile user and the information server. Security and performance analysis shows that the proposed protocol is very suitable for mobile environments.

Quantum simulation promises to have wide applications in many fields where problems are hard to model with classical computers. Various quantum devices of different platforms have been built to tackle the problems in, say, quantum chemistry, condensed matter physics, and high-energy physics. Here, we report an experiment towards the simulation of quantum gravity by simulating the holographic entanglement entropy. On a six-qubit nuclear magnetic resonance quantum simulator, we demonstrate a key result of Anti-de Sitter/conformal field theory(AdS/CFT ) correspondence-the Ryu-Takayanagi formula is demonstrated by measuring the relevant entanglement entropies on the perfect tensor state. The fidelity of our experimentally prepared the six-qubit state is 85.0% via full state tomography and reaches 93.7%if the signal-decay due to decoherence is taken into account. Our experiment serves as the basic module of simulating more complex tensor network states that exploring AdS/CFT correspondence. As the initial experimental attempt to study AdS/CFT via quantum information processing, our work opens up new avenues exploring quantum gravity phenomena on quantum simulators.

We present the first results from an all-sky all-frequency (ASAF) search for an anisotropic stochastic gravitational-wave background using the data from the first three observing runs of the advanced LIGO and advanced Virgo detectors. Upper limit maps on broadband anisotropies of a persistent stochastic background were published for all observing runs of the LIGO-Virgo detectors. However, a broadband analysis is likely to miss narrowband signals as the signal-to-noise ratio of a narrowband signal can be significantly reduced when combined with detector output from other frequencies. Data folding and the computationally efficient analysis pipeline, PyStoch, enable us to perform the radiometer map-making at every frequency bin. We perform the search at 3072 HEALPix equal area pixels uniformly tiling the sky and in every frequency bin of width 1/32 Hz in the range 20–1726 Hz, except for bins that are likely to contain instrumental artefacts and hence are notched. We do not find any statistically significant evidence for the existence of narrowband gravitational-wave signals in the analyzed frequency bins. Therefore, we place 95% confidence upper limits on the gravitational-wave strain for each pixel-frequency pair, the limits are in the range (0.030−9.6)×10−24. In addition, we outline a method to identify candidate pixel-frequency pairs that could be followed up by a more sensitive (and potentially computationally expensive) search, e.g., a matched-filtering-based analysis, to look for fainter nearly monochromatic coherent signals. The ASAF analysis is inherently independent of models describing any spectral or spatial distribution of power. We demonstrate that the ASAF results can be appropriately combined over frequencies and sky directions to successfully recover the broadband directional and isotropic results.

DOAS: Efficient data owner authorized search over encrypted cloud data

Peer-to-Peer Networking and Applications 2016年第3期11卷 349-360页

Data outsourcing service can shift the local data storage and maintenance to cloud service provider (CSP) to ease the burden from data owner, but it brings the data security threats as CSP is always considered to honest-but-curious. Therefore, searchable encryption (SE) technique which allows cloud clients (including data owner and data user) to securely search over ciphertext through keywords and selectively retrieve files of interest is of prime importance. However, in practice, data user’s access permission always dynamically varies with data owner’s preferences. Moreover, existing SE schemes which are based on attribute-based encryption (ABE) incur heavy computational burden through attribution revocation and policy updating. To allow data owner to flexibly grant access permissions, we design a secure cryptographic primitive called as efficient data owner authorized search over encrypted data scheme through utilizing identity-based encryption (IBE) technique. The formal security analysis proves that our scheme is secure against chosen-plaintext attack (CPA) and chosen-keyword attack (CKA) without random oracle. Besides, empirical experiments over real-world dataset show that our scheme is efficient and feasible with regard to data access control.

As one of the most important deep learning models, convolutional neural networks (CNNs) have achieved great successes in a number of applications such as image classification, speech recognition and nature language understanding. Training CNNs on large data sets is computationally expensive, leading to a flurry of research and development of open-source parallel implementations on GPUs. However, few studies have been performed to evaluate the performance characteristics of those implementations. In this paper, we conduct a comprehensive comparison of these implementations over a wide range of parameter configurations, investigate potential performance bottlenecks and point out a number of opportunities for further optimization.

Attack on an ID-based authenticated group key exchange protocol with identifying malicious participants

引用

International Journal of Network Security 2016年第2期18卷 393-396页

作者： Wei, Fushan Wei, Yun Ma, Chuangui School of Computer Science and Technology Xidian University No. 2 South Taibai Road Xian Shanxi710071 China State Key Laboratory of Mathematical Engineering and Advanced Computing No. 92 Kexue Road Zhengzhou Henan450001 China

An authenticated group key exchange (AGKE) protocol allows a group of participants to establish a common session key and then provides secure group communications in collaborative and distributed applications. Recently, Wu et al. proposed an ID-based authenticated group key exchange protocol based on bilinear pairings. They claimed that their protocol can detect and identify the malicious participants, which means it not only can check whether malicious participants exist in the protocol or not, but also can find out who the malicious participants are. However, their protocol is not as secure as claimed. In this letter, we show that Wu et al.'s protocol is insecure against an insider colluding attack. Two malicious participants can collude to impersonate several honest participants to the rest participants in the group. In addition, we also figure out what has gone wrong with Wu et al.'s protocol and how to fix it.

Traditional Relation Extraction (RE) trains individual extractors for pre-defined relations. Open Relation Extraction (ORE) can eschew domain-specific training data, tackle an unbounded number of relations, and scale up to massive and heterogeneous corpus such as the web. However, It is difficult to process micro log texts: the genre is noisy, utterances are very short, and texts have little context. As such, conventional RE approaches fail when faced with micro log and other Web texts. In this paper, we present a gravitation-based Chinese ORE approach to extracting relations between entities by using the idea of the law of universal gravitation. GCORE produces heuristic rules to extract entity relations, and calculates a confidence score for each relational tuple, which is directly proportional to the product of the frequency of entity pairs and the frequency of relation words, and inversely proportional to the square of the distance between the relation word and the candidate entity pair. The confidence score can be used to show the reliability of relational tuples. The higher the score, the more reliable the candidate tuple is, and vice versa. The experimental evaluation over two data sets from ZORE demonstrates the correctness and effectiveness of our proposed approach, and empirical results on Weibo texts show the universality of GCORE. © 2015 IEEE.
