By offering indisputable advantages over traditional grid including remote readings and load balancing, smart grid is regarded as the modernization of the electricity delivery system. In this paper, we propose a privacy-preserving and secure multi-dimensional aggregation scheme for smart grid communications in digital communities. By integrating privacy homomorphism encryption with aggregation signature scheme, data authentication and integrity protection are performed and proved without disclosing any fine-grained user consumption data. The construction of member list allows the fault tolerance of our scheme against accidental errors. In addition, the batch verification technique is adopted to reduce the computation cost of the operation center, and each user's computation cost is independent of the number of collected data types. security analysis and performance evaluation demonstrate that the proposed scheme can resist various security threats and preserve identity privacy and has significantly less communication overhead and computation cost than other existing approaches.

Automatic classification of the modulation format of a detected signal plays an important role in cognitive radio system and several military and civilian applications. Without previous knowledge of the received data, automatic modulation classification (AMC) becomes a difficult task. This paper discusses AMC of digital schemes which are commonly used in today's communication systems. Several statistical features are extracted to represent signals and Support Vector Machines (SVMs) are then applied to classify the unknown modulation schemes. Experiment results demonstrate that the proposed AMC algorithm is a practical algorithm and it has high robustness in a wide range of SNR.

Models of quantum systems on curved space-times lack sufficient experimental verification. Some speculative theories suggest that quantum properties, such as entanglement, may exhibit entirely different behavior to purely classical systems. By measuring this effect or lack thereof, we can test the hypotheses behind several such models. For instance, as predicted by Ralph and coworkers [T C Ralph, G J Milburn, and T Downes, Phys. Rev. A, 79(2):22121, 2009;T C Ralph and J Pienaar, New Journal of Physics, 16(8):85008, 2014], a bipartite entangled system could decohere if each particle traversed through a different gravitational field gradient. We propose to study this effect in a ground to space uplink scenario. We extend the above theoretical predictions of Ralph and coworkers and discuss the scientific consequences of detecting/failing to detect the predicted gravitational decoherence. We present a detailed mission design of the European Space Agency's (ESA) Space QUEST (Space - Quantum Entanglement Space Test) mission, and study the feasibility of the mission scheme.

IEEE Asia-Pacific Conference on Antennas and Propagation (APCAP)

作者： Jun Hua Science and Technology of Communication and Information Security Control Laboratory Jiaxing Zhejiang Province China

A new fast numerical algorithm for the double-order double-argument Hankel transformation is proposed in this article. Due to the fact of rapid oscillation and slow attenuation of the kernel function, it is difficult to compute numerically. The New Algorithm break up the infinite integral interval into two subintervals. For the infinite subinterval, the integral can be calculated by Fast Fourier Transformation (FFT) efficiently; For the other finite integral, there has two choice, the one is ordinary quadrature algorithm which is simple but no efficient enough, the other is to express the integral as a summation series of the Bessel function integral, and then the calculus can be done with more efficient manner.

General Assembly and Scientific Symposium, URSI

作者： Hua Jun Science and Technology of Communication and Information Security Control Laboratory Jiaxing Zhejiang Province P.R. China

A new proper integral representation of the first order Marcum Q-function Q(a, b) is derived and proved in this article. The most special feature of this form is that it holds the same representation for any value of arguments ratio a/b, meanwhile, it is can be used for stable numerical quadrature directly, and furthermore, it is also useful in the performance analysis of radar detection and digital communication systems analytically. The correctness of this new form is checked by the numerical comparison with the definition form of Marcum Q-function over a small and large domains in its two arguments.

A game model is proposed for the indirect trust information obtaining process. A suitable punishment mechanism and design the utility function for nodes in a MANET is given. Moreover, with evolutionary game theory, the trust evolution of nodes using replicator dynamic equation is analyzed and several theorems toillustrate preconditions under which each evolutionarily stable strategy can be achieved are proposed. Experiments verified the correctness and effectiveness of proposed method and simulated the dynamic evolutionary trend of the nodes under different parameters which experimentally proves the proposed theorems. ©, 2014, Editorial Board of Journal on communications.

The routing protocol is the core of the Ad Hoc network protocols, which largely determines the performance and features of an Ad Hoc network. Aiming at the characteristics of the Mobile Radio Ad Hoc network, this paper is to design a low-rate mobile Ad Hoc network routing protocols WLRP (Wireless Low-Rate Ad Hoc security Routing Protocol), using the trust evaluation mechanism between neighbour nodes which can effectively prevent attacks from inside the network, to greatly enhance the Ad Hoc Network security. Simulation results show that in low-Rate link environment, the WLRP protocol performs better than AODV.

A wideband spectrum sensing procedure based on the idea of group testing is proposed in this paper. A new polyphase filter bank (PFB) for which the output subbands have the same bandwidth and contain continuous frequency components is proposed. This PFB is utilized to form a two-stage wideband spectrum sensing method. The simulations show that the proposed method can reduce the number of binary tests greatly when the number of occupied primary channels is low.
