    Wireless key generation system for internet of vehicles based on deep learning by Han WANG, Liquan CHEN, Zhongmin WANG, Tianyu LU

    Published 2024-02-01
    “…In recent years, the widespread application of internet of vehicles technology has garnered attention due to its complex nature and point-to-point communication characteristics.Critical and sensitive vehicle information is transmitted between different devices in internet of vehicles, necessitating the establishment of secure and reliable lightweight keys for encryption and decryption purposes in order to ensure communication security.Traditional key generation schemes have limitations in terms of flexibility and expandability within the vehicle network.A popular alternative is the physical layer key generation technology based on wireless channels, which offers lightweight characteristics and a theoretical basis of security in information theory.However, in the context of internet of vehicles, the movement speed of devices impacts the autocorrelation of generated keys, requiring improvements to traditional channel modeling methods.Additionally, the randomness and consistency of generated wireless keys are of higher importance in applications in internet of vehicles.This research focused on a key generation system based on the wireless physical layer, conducting channel modeling based on line-of-sight and multipath fading effects to reflect the impact of vehicle speed on autocorrelation.To enhance the randomness of key generation, a differential quantization method based on cumulative distribution function was proposed.Furthermore, an information reconciliation scheme based on neural network auto-encoder was introduced to achieve a dynamic balance between reliability and confidentiality.Compared to the implementation of Slepian-Wolf low-density parity-check codes, the proposed method reduces the bit disagreement rate by approximately 30%.…”

    Application of Improved Fisher Optimal Segmentation Method Based on Combined Weight Method in Reservoir Flood Season Staging by XIA Qingqing, LI Yinghai, LIU Fen, LAO Jiapeng, TIAN Lijuan

    Published 2024-01-01
    “…In Fisher optimal segmentation method,multi-index weighting only considers a single objective weighting method.To overcome the shortcoming,this paper introduces the entropy weight method based on information theory,the coefficient of variation method based on statistical principle,and the CRITIC weighting method in the calculation of index weight.It proposes the Fisher optimal segmentation method based on combined weight.Taking Shuibuya Reservoir as an example,five indicators are selected,including the average flow in ten days,the number of occurrences of the maximum peak flood flow,the maximum one-day flood volume in ten days,the maximum three-day flood volume in ten days,and the maximum seven-day flood volume in ten days.Then the Fisher optimal segmentation method is applied to divide the flood season,and the staging results are compared with the staging results by a single objective weighting method.It is determined that the flood season is divided into three optimal periods.The pre-flood season is from May 1 to June 10,the main flood season from June 11 to July 31,and the post-flood season from August 1 to September 30.The results show that the combined weight method takes into account the advantages of the entropy weight method,the coefficient of variation method,and the CRITIC weighting method.The method can intuitively distinguish the influence degree of different indexes on flood season staging and is suitable for determining multi-index weight in the Fisher optimal segmentation method.…”
