    Design of multi-key encryption method by Yuqing ZHONG, Hao WANG, Zebing LIN, Min WANG, Liye CHEN

    Published 2020-11-01
    “…In order to improve the security in the process of information transmission,the current encryption methods were studied,and the research status was reported which increased the security of encryption by processing the key.According to the principle of segmenting and grouping data in the process of sending and encrypting,a method of multi-key encryption was designed:the segmenting key group and grouping key group were generated by the source key and random number,and the corresponding key was selected for each segmented and grouped data by its sequence number according to the matching algorithm.This method realized the encryption of multi-key in the process of information transmission.Finally,on the one hand,MATLAB was used to test and verify the encryption efficiency of this method.On the other hand,the security of this method was analyzed from the theoretical and mathematical perspective,comparing with the traditional method.It is concluded that this method can increase the security of the traditional method without too much cost much cost.…”

    Fault Diagnosis of Vehicle Gearbox based on Support Vector Machine Optimized by Improved Beetle Antennae Search by Wenshan Qiao, Jin Hua, Meihong Chen

    Published 2022-05-01
    “…Aiming at the fact that the performance of support vector machine (SVM) in vehicle gearbox fault diagnosis is greatly affected by parameters,a new method of vehicle gearbox fault diagnosis based on improved SVM is proposed based on the research of beetle antennae search (BAS). Compared with BAS,IBAS modified the step size formula and added Gaussian variation behavior,so that the search ability of the algorithm in the early and late period is balanced and has the ability to jump out of the local optimal,and better SVM parameters could be obtained. …”
