Artificial noise-aided robust secure information and power transmission scheme in heterogeneous networks with simultaneous wireless information and power transfer by Bo ZHANG, Kaizhi HUANG, Zhou ZHONG, Yajun CHEN

“…A heterogeneous network with simultaneous wireless information and power transfer under the stochastic channel state information (CSI) error was considered.In this network,to guarantee the security and reliability of information and energy transmission,an artificial noise (AN)-aided robust secure information and power transmission scheme was proposed.By jointly designing the downlink information beamforming and AN matrix of macrocell base station and femtocell base stations,the eavesdroppers were jammed and the energy receiving performance of system was improved simultaneously.The problem of maximizing the energy receiving performance was modeled under the constraints on the base station power,the outage probability of information transfer and confidential information eavesdropped.Due to the probabilistic and rank-one constraints,this problem was non-convex.To obtain the solution,the original problem was first transformed into an equivalent form,which was easy to process.Then,the Bernstein-type inequality and the Large-deviation inequality was utilized to transform the outage probability limits into convex linear matrix inequalities,respectively.Finally,the rank-one beamforming constraints were processed with quadratic equality constraint procedure.Simulation results show that the proposed scheme has higher energy receiving performance and feasible performance in comparison with compared schemes,which validates the effectiveness and the robustness of our proposed scheme.…”

Indoor wireless signal coverage and enhancement based on passive reconfigurable intelligent metasurface by Haixia LIU, Hao YI, Xiangjin MA, Shuyao YUE, Xudong KONG, Pei MA, Yuxin ZENG, Long LI

“…Reconfigurable intelligent metasurface (RIS) is a new type of artificial electromagnetic metamaterial, which can control the frequency, amplitude, phase, polarization, propagation direction and wave type of electromagnetic wave flexibly.In the field of wireless communication, RIS can be used to reconstruct the wireless communication channel to achieve blind coverage of wireless signals and improve the communication quality.First, the development and research status of RIS, the key technologies and application scenarios of RIS were summarized and analyzed.Then, a new passive RIS was proposed to realize the characteristics of the aperture reconfiguration and beam reconfiguration through passive coding and splicing principle, which had the advantages of low cost, low power consumption and low complexity.Finally, the blind area coverage enhancement experiment of indoor wireless signal based on passive reflection metasurface was carried out.The effectiveness of passive splicing metasurface in wireless communication blind coverage scenarios was proved by comparison between simulation and field measurement.In addition, for 5G/6G millimeter wave communication, the passive RIS with double-layer cross dipole elements was designed and applied to typical indoor L-shaped corridor scene to verify the enhancement effect of indoor wireless signal coverage.…”

Blockchain-based and verifiable multidimensional data aggregation and sharing scheme for smart grid by Jianwei CHEN, Shuyu WANG, Meiping ZHANG, Zhenping ZHANG

“…Aiming at the problem that how to support lightweight multi-dimensional data aggregation, achieve double-end integrity verification of multi-dimensional data in the overall process of the system, and deal with the centralization of cloud servers, a blockchain-based and verifiable multidimensional data aggregation and sharing scheme for smart grid was proposed.Firstly, in order to meet the demand for fine-grained analysis of power data in smart grid, privacy-preserving multidimensional data aggregation was achieved by using masked values and Horner’s rule.On this basis, for the data integrity verification problem of the existing data aggregation scheme in the sharing of cloud storage data with the third party, a new signature algorithm was designed by borrowing the RSA-based multiplicative homomorphic commitment scheme and homomorphic hash function homomorphism, which enabled the cloud server to verify the integrity of aggregated data and be used for integrity verification in the data sharing phase, i.e., it achieved double-end verifiability of cloud storage data and was resistant to internal attacks.Meanwhile, an aggregated data sharing architecture based on federated chain multichain was proposed to effectively avoid centralisation problems such as single-machine processing bottleneck and vulnerability to attacks.The theoretical analysis proves the security of the scheme.Performance experiments show that the proposed scheme has lower computation and communication costs compared with existing schemes.…”
