Research Prospect of Anti-Jamming Strategy for the Satellite Internet by Chen HAN, Aijun LIU, Kang AN

“…As an important infrastructure of the national information system, the satellite internet is of great signifi cance to the national security.Thus, it needs to ensure the validity and reliability of the data transmission in the hostile jamming environment.The threat of smart jamming and the limitation of classical link-layer anti-jamming methods give rise to the new demand of intelligent and networked antijamming solutions.In view of the structural characteristics of the satellite internet and the development trend of modern communication jamming technologies, this paper analyzed the basic architecture of intelligent and networked anti-jamming.Based on the closed-loop strategic of sense-learn-prediction-decision-feedback, intelligent and active anti-jamming decision was made to realized self-confi guration and self-optimization.Based on the cooperative communication between nodes, networked anti-jamming ability was improved by the means of topology control and reconstruction, adjacent resources reallocation, and traffi c load balancing.It provided certain theoretical support for the construction of anti-jamming strategy system to achieved the cross-layer optimization, multi-domain combination, and adaptive intelligence.…”

Combined encryption method for CAN bus data based on periodic coupled processing by Wutao QIN, Peng WANG, Yufeng LI

“…In the intelligent connected age, CAN bus transmission faces the urgent demand of light weighted security encryption.Based on this, a fast response and high security CAN bus data encryption method was proposed.Since the 64 bit CAN packets were sent periodically, an online-offline block encryption algorithm coupled with message transmission cycle was proposed.In offline phase, the dynamic session key was generated by using advanced encryption standard.In online phase, the dynamic session key was used to quickly respond to encryption and decryption requests.The online computation delay was greatly reduced by the pre-encryption computation in offline phase, which helped achieving low latency and lightweight computation.At the same time, the ciphertext policy attribute based encryption was used to encrypt the block cipher.The access control policy made by the data sending OBU ensures that only the target OBU can decrypt the block cipher, so as to achieve targeted encryption.…”

Image encryption method based on multiple-order fractional discrete Tchebichef transform and generating sequence by Bin XIAO, Wenming SHI, Weisheng LI, Jianfeng MA

“…Fractional transform based image encryption methods have been widely studied in recent years.However,most of the existing fractional transform based image encryption methods are defined in the complex field.Thus,the encrypted images contain both phase and amplitude information,which is not conducive to transmission and storage.Moreover,some encryption methods that meet the requirements of reality-preserving have problems of relatively single keys,lacking of sensitivity and so on.An image encryption method was proposed based on multiple-order fractional discrete Tchebichef transform and generating sequence.The proposed method used randomly generated row and column vectors and generating sequence generated by Chaotic sequences as keys to encrypt images,which not only satisfied property of reality-preserving transmission but also greatly expanded the key space.The experimental results further demonstrate that the proposed encryption method can resist a variety of attacks,and decrypted images are almost non-distored,which indicate excellent encryption effect,sufficient security and robustness of the method.…”

State-of-the-art and trend of emergency rescue communication technologies for coal mine by Qingsong HU, Wei YANG, Enjie DING, Shiyin LI, Binghao LI

“…For the disaster area probing and emergency rescue in a mine,it is of great importance to employ the emergency communication system to communicate with each other,determine the places of trapped miners,and sense current status of disaster area.The hybrid emergency communication architecture model for coal mines was extracted,which was composed of one backbone,multiple branches,several special lines,and some wireless networks as assistance.Four types of emergency communication systems of coal mine were reviewed,namely through-the-air,through-the-wire,through-the-earth and mixed medium type.The key technologies and challenges of these four emergency communication types were analyzed.The research trend was discussed and a new emergency communication mode based on the reconstruction of mine Internet of things was proposed.The main enabling technologies of this new emergency communication mode were analyzed,namely post-disaster reconstruction of mine Internet of things,shifting nodes re-localization after mine disaster,status sensing method of mine disaster area,and data transmission method for post-disaster reconstruction network.…”

Research on PAPR reduction algorithm based on CWGAN-SLM for multi-wavelet OFDM system by Guang YANG, Zhaoyang WU, Min NIE, Xiaohong YAN, Fan JIANG

“…In order to meet the demand for low peak to average ratio (PAPR) of orthogonal frequency division multiplexing (OFDM) technology in the future 6G satellite-ground integrated system, an algorithm combining selective mapping (SLM) algorithm and multi-wavelet OFDM technology was proposed firstly.However, the PAPR reduction was limited and the computational complexity was high.To solve this problem, a multi-wavelet OFDM PAPR reduction algorithm based on conditional Wasserstein generative adversarial network (CWGAN) and SLM was proposed, which was called CWGAN-SLM algorithm.CWGAN was introduced to generate more time-domain alternative signals to reduce the PAPR in the CWGAN-SLM algorithm.Simulation results indicate that the CWGAN-SLM algorithm greatly reduces the PAPR of the system and the computational complexity, and has a lower bit error rate.Compared with the GAN and WGAN, the CWGAN has the advantages of easy training, strong stability and good PAPR performance.…”
