The anti-UAV equipment on the domestic market has a single function and a small number, and it is easy to cause secondary damage after countering low-altitude UAVs. There are many ways to counter drones, but the method of using pseudolite signals for electronic spoofing is relatively effective and minimizes damage. This paper proposes a countermeasure against low-altitude UAVs based on software radio emitting pseudolite signals, which can guide low-altitude UAVs to a set direction, which can effectively counteract low-altitude UAVs. The full text first gives the system flow chart, then uses software radio to transmit pseudolite signals, uses GNU Radio to construct the GRC flow chart and conducts signal testing, and finally builds the hardware platform and conducts outdoor testing.","PeriodicalId":403102,"journal":{"name":"2021 International Symposium on Computer Technology and Information Science (ISCTIS)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126760485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the era of 5G business and the Internet of Everything, high reliability and low delay of information on high-speed channels provide good basis for the application of fast image encryption algorithm. In this paper, a fast image encryption algorithm based on the improved chaotic model was proposed by using the multiplicative large integer modulo method to homogenize the Logistic map. In the encryption algorithm, the scrambling and diffusion are processed simultaneously, which makes this scheme own high speed.

The existence of security holes in the executable programs in the IoT devices has resulted in difficult to estimate security risks. For a long time, vulnerability detection is mainly completed by manual debugging and analysis, and the detection efficiency is low and the accuracy is difficult to guarantee. In this paper, the mainstream automated vulnerability analysis methods in recent years are studied, and a vulnerability detection algorithm based on symbol execution is presented. The detection algorithm is suitable for lightweight applications in small and medium-sized IoT devices. It realizes three functions: buffer overflow vulnerability detection, encryption reliability detection and protection state detection. The robustness of the detection algorithm was tested in the experiment, and the detection of overflow vulnerability program was completed within 2.75 seconds, and the detection of encryption reliability was completed within 1.79 seconds. Repeating the test with multiple sets of data showed a small difference of less than 6.4 milliseconds. The results show that the symbol execution detection algorithm presented in this paper has high detection efficiency and more robust accuracy and robustness.","PeriodicalId":403102,"journal":{"name":"2021 International Symposium on Computer Technology and Information Science (ISCTIS)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116839639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A monitoring method for tool wear degree based on the signals of sound and current is proposed in this paper, and five kinds of tools with different wear grades are analyzed by using this method. The statistical characteristics of the sound and the current in the time-frequency and psycho-acoustic domains are used to extract the features of drill bits in the proposed method, and the whale optimization algorithm (WOA) is used to optimize features. Finally, the five classifications of twist drill wear degree are realized by K-Nearest Neighbors (KNN).
