At Eurocrypt 2010, van Dijk et al. described a fully homomorphic encryption scheme (abbreviated as DGHV) over integers. It is conceptually simple but the public key size is large. After DGHV scheme was proposed, many variants of DGHV schemes with smaller public key size were proposed. In this paper, we present a multi-ciphertexts attack on a variant of the DGHV scheme with much smaller public key (abbreviated as HERK), which was proposed by Govinda Ramaiah and Vijaya Kumari at CNC 2012. Multi-ciphertexts attack considers the security of the schemes when the attacker captures a certain amount of ciphertexts. It is a common phenomena that the attacker can easily obtain enough ciphertexts in most of practical applications of fully homomorphic encryptions (even for public-key schemes). For all the four groups of the recommended parameters of HERK, we can recover the plaintexts successfully if we only capture five ciphertexts. Our attack only needs to apply LLL algorithm twice on two small dimension lattices, and the data show that the plaintexts can be recovered in seconds. © Springer International Publishing AG 2017.

In article number https://***/10.1002/advs.201900460 , Hua Li, Juncheng Cao, Kai Zhang, Heping Zeng, and co‐workers report a graphene‐based approach for enhanced passive frequency comb operation and pulse generation in terahertz semiconductor lasers. The saturable absorption and group velocity dispersion compensation provided by a multi‐layer graphene sample result in a laser frequency comb operation with highly stabilized frequency lines and optical pulse generation (16 ps) in the terahertz regime.

Polymorphic transitions in layered transition metal dichalcogenides provide an excellent platform for discovering exotic phenomena associated with metastable states, ranging from topological phase transitions1 to enhanced superconductivity2. In particular, the transition from 2H to 1T0-MoTe2, which was thought to be induced by high-energy photon irradiation3–5 among many other means6–9, has been intensely studied for its technological relevance in nanoscale transistors3. Despite the remarkable electrical performance arising from this 2H-to-1T0 transition, it remains controversial whether a crystalline 1T0 phase is produced because optical signatures of this putative transition are found to be associated with the formation of elemental Te clusters instead10,11. Here, we demonstrate the creation of an intrinsic 1T0 lattice after irradiating a mono- or few-layer 2H-MoTe2 with a single field-enhanced terahertz pulse, whose low photon energy limits possible structural damage by optical pulses. To visualize the temporal evolution of this irreversible transition, we further develop a single-shot terahertz pump-second harmonic probe technique, and we find that the transition out of the 2H phase occurs within 10 ns after photoexcitation. Our results not only resolve the long-standing debate over the light-induced polymorphic transition in MoTe2, they also highlight the unique capability of strong-field terahertz pulses in manipulating the structure of quantum materials.

Well logging data are important to evaluate rock and fluid properties underground. Many well logging data, as functions of well depth, are conserved as figures in the literature. Digitizing technics should be applied when utilizing the well logging data. In order to address this problem, a method was proposed to automatically identify and acquire the well logging data from well logging curves. Based on the color recognition, this algorithm is able to extract curve features based on pixels. Comparing to other data digitizing methods, the background grid lines could be easily filtered and removed. The algorithm is verified by digitizing some typical well logging curves. This main contribution of this work is to provide a new and efficient way for data digitizing from well logging curves.

Rectangle transformation problem

In this paper, we propose the rectangle transformation problem (RTP) and its variants. RTP asks for a transformation by a rectangle partition between two rectangles of the same area. We are interested in the minimum RTP which requires to minimize the partition size. We mainly focus on the strict rectangle transformation problem (SRTP) in which rotation is not allowed in transforming. We show that SRTP has no finite solution if the ratio of the two parallel side lengths of input rectangles is irrational. So we turn to its complement denoted by SIRTP, in which case all side lengths can be assumed integral. We give a polynomial time algorithm ALGSIRTP which gives a solution at most q/p + O(√p) to SIRTP(p,q)(q ≥ p), where p and q are two integer side lengths of input rectangles p×q and q×p, and so ALGSIRTP is a O(√p)-approximation algorithm for minimum SIRTP(p,q). On the other hand, we show that there is not constant solution to SIRTP(p,q) for all integers p and q (q > p) even though the ratio q/p is within any constant range. We also raise a series of open questions for the research along this line. Copyright © 2017, The Authors. All rights reserved.

Find out the potential favorite data is the essence of recommendation techniques, which facilitates the recommendation techniques become a vital issue in the big data researches and applications. The traditional recommendation research and application centers on the commercial items and resources. We apply the recommendation to social relationships in social networks. We design a framework which can analyze and recommend various types of relationships. The framework has four modules and three work modes. Furthermore, we design a hybrid recommendation approach in the framework for the balancing between accuracy and efficiency. The framework can recommend the social relationships with high accuracy and low cost.

An intra-body communication (IBC) research platform based on virtual instrument was established for the hardware design of IBC transceiver. Firstly, the feasibility of constructing IBC research platform using optic-coupling circuit was verified via comparison of three kinds of measurement methods based on virtual instrument. Then, ASK, FSK and BPSK modulation-demodulation were realized via labVIEW programming, and user interface of the platform was also designed. The platform could achieve signal transmission or recover under different coupling type, different channel distance and different modulation-demodulation method, etc., by means of dynamic adjusting of platform parameters. Experiment results of capacitive-coupling under the platform indicated the authenticity and feasibility of signal transmission. Finally, a full-floating IBC transceiver was designed aided by the parameters provided by the research platform under the scene of capacitive-coupling, FSK modulation and 180 cm channel distance. Moreover, Bit Error Rate (BER) of the transceiver was less than 1e-5, which meant that it is effective and convenient for the design of IBC transceiver aided by virtual instrument platform. © 2017 IEEE.
