The algorithm first detects noise, introduces the minimum absolute brightness difference to reflect the difference between candidate noise pixels and surrounding non-noise pixels, and innovatively sets a linear threshold, which is adapted to the local noise density and compared with the minimum absolute brightness difference to distinguish noise pixels. When removing noise, the window size used is determined by the extreme pixel density in the window, and the median of the non-extreme pixel in the window is used for replacement. The methods mentioned in this paper are compared with Standard Median Filter (SMF), Adaptive Median Filter (AMF), Modified Adaptive Median Filter (MAMF), Switching Median Filter (SWMF), Adaptive Switching Median Filter (ASMF), the Decision Based Algorithm (DBA), and the Modified Decision Based Algorithm (MDBA). The experimental results show that, compared with the existing methods, the method proposed in this paper better considers the local characteristics of the image, and has better processing effect under various noise densities.","PeriodicalId":325919,"journal":{"name":"2022 21st International Symposium on Communications and Information Technologies (ISCIT)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124504742","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 order to make better use of the adversarial examples, rather than just taking it as the defects of neural network, a covert communication method based on adversarial examples is proposed in this paper. Using the characteristics that adversarial examples can carry information, we combine it with specific coding rules to develop a covert communication algorithm. Unlike the traditional steganography, the secret information is not contained in the communication content of the sender and the receiver itself in the proposed scheme. The mapping relationship between adversarial examples and secret information is hidden in the neural network model, so as to realize the hidden transmission of information and improve the concealment and security of communication. At the same time, the tamper identification is embedded in the tensor of adversarial output. When the image is modified during transmission, the tamper identification will also change, so that the image can be authenticated. Experiments show the feasibility of the algorithm and verify that it can completely extract secret information from the encrypted image adversarial example and authenticate the integrity of the image.","PeriodicalId":325919,"journal":{"name":"2022 21st International Symposium on Communications and Information Technologies (ISCIT)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125276041","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}

It is also necessary to design how to work the instructions in hardware circuits of the MPU. As a solution to these, we previously proposed a method of expressing the instruction in two ways of semantic expression and functional expression. We also developed a tool that can visualize the instruction. In this paper, we have improved this method by extending a usual MPU to a meta-instruction for any MPU. We have also developed a conversion method for the meta-instruction using a relationship between the semantic and the functional expressions. Then we verified how well our meta-instruction can represent the usual instructions. It is confirmed that most of them can be represented by the meta-instruction. Since our developed tool user can design the meta-instructions from either semantic or functional expression and both expressions can be automatically converted to each other, they can design the instruction of a new MPU and can understand hardware circuits for the MPU instruction by the functional expression.","PeriodicalId":325919,"journal":{"name":"2022 21st International Symposium on Communications and Information Technologies (ISCIT)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117097831","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}

Among them, the electronic auction technology based on the IoT has been applied. The traditional electronic auction scheme cannot be flexibly applied in IoT scenario and most auction schemes often have only one authority, which has a great burden on operation and low efficiency, resulting in a single-point performance bottleneck. In order to solve above problems, we use a hierarchical multiple authorities system to propose a Robust Auction scheme with Multiple Authorities in IoT (RAMA). Besides, a lightweight range query protocol which can get the highest bidder in electronic auction is adopted to avoid deploying expensive sensors and aggregators in the IoT configuration. Moreover, security of the hierarchical multiple authorities system have been proved through rigorous security analysis, which indicate that the adopted range query protocol not only ensures the security of encrypted bidding but also prevents it from being stolen by malicious adversaries. Finally, we conduct simulation experiments and analyze experimental results to verify the feasibility of the scheme. Specifically, when the number of bidders is 1000, the time-consuming to generate the secret key and the time-consuming to obtain the maximum bidding price are not exceed 0.5s in the simulation experiment.","PeriodicalId":325919,"journal":{"name":"2022 21st International Symposium on Communications and Information Technologies (ISCIT)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117345203","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}

Despite its significant advantages, the offline site surveys to collect fingerprints to construct a radio map for precise localization in the online phase remain the key challenge because it requires tremendous human effort, time, and cost. To alleviate this issue, this paper presents a novel fingerprint interpolation technique for constructing the radio map based on reference point (RP) clustering and the Voronoi diagram. Firstly, the collected RPs are clustered based on a threshold value of received signal strength difference using the proposed clustering algorithm. A Voronoi diagram is drawn using the centroid of each cluster to partition the clusters in which virtual fingerprints are then generated using the Kriging interpolation algorithm to build a complete radio map. By grouping RPs with similar characteristics in the same region, more accurate virtual fingerprints can be inferred since the RPs in the same region have the tendency to experience similar multipath fading and signal shadowing effects. Experimental results show that the proposed scheme reduces the localization error up to 14% compared to the interpolation without clustering. As a result, we can overcome the site survey issues for IPS by constructing a radio map with more accurate localization results.","PeriodicalId":325919,"journal":{"name":"2022 21st International Symposium on Communications and Information Technologies (ISCIT)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125638967","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}
