With the development of cloud computing, data security issues have become increasingly prominent. As an encryption method that can perform calculations in the ciphertext domain, homomorphic encryption technology provides an effective solution for data security in a cloud computing environment. data security technology based on homomorphic encryption is the main subject of this paper. First, the classification and characteristics of homomorphic encryption technology are introduced, as well as security analysis methods, and then a data security system based on fully homomorphic encryption is designed, including data acquisition and preprocessing modules. Then, the data analysis module adopts a model structure based on a neural network and provides the model training and parameter optimization process. Finally, experiments were conducted based on real data sets to verify the feasibility and effectiveness of the system, and the system was evaluated from the aspects of accuracy, time overhead, and storage overhead. This paper concludes that homomorphic encryption technology can guarantee data privacy and integrity in a cloud computing environment while also improving computing efficiency and scalability. © 2023 IEEE.

Firstly, this paper studies the overall structure, key technologies and core hardware design of the high-resolution satellite image data receiving and processing system. The system adopts a real-time parallel image data receiving and processing algorithm based on RS error correction coding. At the same time, according to the characteristics of a single chip, combined with software design, the system has made corresponding research on RS decoding, noise reduction and signal processing software, and has carried out effective scheme and simulation verification design for different needs. The system can provide users with an intuitive and accurate user experience by using real-time point to point data transmission and automatic analysis of processing results for calculation. Image signal has rich and bright color expression and clarity. Compared with similar data sources, the spatial resolution is greatly improved. In traditional image processing, channel coding is the simplest and most convenient coding method, but it is more serious for low noise and inter symbol interference;Now, the satellite image data processing is basically to compress and store the collected data, decode and compress them, and then upload them. In this way, the decoder and storage device do not need to work at the same time, and the computing resources are greatly increased. © 2023 IEEE.

Everyone comes under the problem, Security. Comparative to Wired network, wireless faces more problem and also it is inevitable. This paper deals how to reduce security issue and also to avoid traffic conjunction. Here, we explain how the misbehavior node is detected by the auditor in dynamic network. Auditing node is used to collect the information of each node and also used to select the trustworthy path to avoid the traffic conjunction and make the data more securable. To increase the security and speed we implement the clustering method. In that various types are used to increase the security, among those types fuzzy is one of them. In fuzzy we used binary method, which make more security in the wireless network.

In this paper, a compact size ultra-wide band pass and bandstop filter using composite right/left-handed (CRLH) transmission line loaded with complementary split ring resonators (CSRRs) in planar technology is presented. The bandpass filter resonating at two resonant frequency band is designed with transmission line loaded with short circuited stub is presented. The using resonant type CSRR metamaterial is implemented to convert the dual band to wide band is shown. Also a comparative study of different types of CSRR metamaterial with their equivalent circuit and their effect on the results is briefly discussed. The total dimension of Compact filter is 9.6x6.5 mm with microstrip line which is above the Roger 3010 substrate gives the passband from 5 GHz to 12 GHz with the return loss of 15dB which is 3GHz improvement in bandwidth comparing with the reference paper. Such small device with wide bandwidth can be easily integrated into the communication systems requiring high data rates.

At present, the fast transmission mechanism of weak signal data at distribution network terminals is mostly cross processing, and the transmission distance is limited, which leads to the increase of data transmission delay. Therefore, this paper proposes to design and verify the fast transmission technology of weak signal data at distribution network terminals based on carrier communication. According to the actual transmission requirements and standards, carry out distributed transmission data acquisition, use mapping standards as a guide, increase the transmission distance, design GOOSE mapping carrier transmission mechanism, and based on this, build a carrier communication weak signal data fast transmission model, and use UDP priority processing to achieve fast data transmission. The final test results show that: after three stages of measurement, the final data transmission delay is well controlled below 10ms, indicating that the control effect of this method is good. For weak signal data, the transmission speed is fast, and the data transmission delay is within a reasonable range, reducing delay jitter while strengthening the transmission effect, which has practical application value. © 2023 IEEE.

Ground Penetrating Radar(GPR) technology is a kind of rapid and continuous detection method with high precision and intuitive image. It is an electromagnetic wave technology used to determine the distribution of the underground media spectrum (1 MHZ - 3 GHZ). The applications of GPR is facing the influence of various interference in various complex environments and the main direction of GPR application research is how to remove interference and how to extract the useful information. The signal processing Is means of the radar to implement the signal retrieval and information extraction. Based on the analysis of the signal processing technology of GPR used commonly, the paper applies these methods to the processing and interpretation of GPR data in an engineering example and illustrates the purpose and the treatment manner of the various signal processing technology.

3rd international conference on Machine Vision and Information Technology (CMVIT)

作者： Qu, Yue Lu, Yunqing Changchun Univ Sci & Technol Changchun Jilin Peoples R China

In the wideband receiving system of radar, it is often necessary to process signals with high sampling rate and wide bandwidth. The sampling rate that the system can process is limited by the design structure of the whole system. Usually, the signal is processed by a polyphase filter bank composed of several low-order filters. The interpolation and decimation of signals are realized at the same time, which further reduces the sampling rate. However, the baseband signal data rate required by the signal processing system may not be obtained by integer decimation of the sampled signal. Therefore, a structure combining parallel polyphase interpolation filtering and parallel polyphase decimation filtering is designed to realize the decimation of L/M multiple of large bandwidth signals without improving the processing clock of the FPGA.

Railway detection task produces a large number of images, the lack of effective image classification method makes it difficult to analyze detection image deeply. Using convolutional neural networks (CNN) to realize railway image scene classification is an effective technical means. This paper propose a method to reduce the bias of database by Gradient-weighted Class Activation Mapping(Grad-CAM) to effectively improve scene classification accuracy, and achieve accuracy of 95.3%(top3) on Railway12 database. Our approach combines two insights: (1) Small quantity of railway scene database make it hard for CNN to achieve high performance, transfer pre-trained ImageNet-CNN to fine-tune on railway scene database (2)Introduce Grad-CAM visualization method to analyze model's classification pattern and intuitively show the possible bias of database, provide an intuitive way to reduce bias of dataset.
