Mathematical models are given that make it possible to calculate the magnetic fields of annular permanent magnets and those formed by current pulses when they flow in a waveguide medium. To calculate the magnetization of the waveguide, a numerical method was developed that allows taking into account the magnetization of the waveguide material at a previous time. Mathematical models are also given to calculate the parameters of the magnetic flux of the solenoid and the output signal. Mathematical models for calculating permanent magnet magnetic fields, the developed numerical method and mathematical models for the formation of magnetic flux and output signal were implemented in the developed software used in the educational process. The research results, as well as refined and developed methods for calculating magnetic fields and the numerical method can be used to study magnetostrictive devices both at the stage of their design and operation, which reduces their final cost. It should also be noted that the article does not address issues related to the processing of the output signal, which provides opportunities for further research and further modification of the software.","PeriodicalId":33459,"journal":{"name":"Trudy Instituta sistemnogo programmirovaniia RAN","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135262540","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}

Sigalov, Maxim Petrovich Malkov","doi":"10.15514/ispras-2023-35(1)-14","DOIUrl":"https://doi.org/10.15514/ispras-2023-35(1)-14","url":null,"abstract":"This paper studies the occurrence of insecure deserialization in communication between client-side code and the server-side of a web application. Special attention was paid to serialized objects sent from JavaScript client-side code. Specific patterns of using serialized objects within the client-side JavaScript code were identified and unique classes were formulated, whose main goal is to facilitate manual and automatic analysis of web applications. A tool that detects a serialized object in the client-side code of a web page has been designed and implemented. This tool is capable of finding encoded serialized objects as well as serialized objects encoded using several sequentially applied encodings. For found samples of serialized objects, the tool determines the context in which the found object appears on the page. For objects inside JavaScript code, the tool identifies the previously mentioned classes by mapping the vertices of the abstract syntax tree (AST) of the code. Web application endpoints were checked for whether programming objects were deserialized on the server side, after obtaining the results of the study. As a result of this check, previously unknown vulnerabilities were found, which were reported to the developers of this software. One of them was identified as CVE-2022-24108. Based on the results of this research, a method was proposed to facilitate both manual and automated searches for vulnerabilities of the \"Deserialization of untrusted data\". The proposed algorithm was tested on more than 50,000 web application pages from the Alexa Top 1M list, as well as on 20,000 web application pages from Bug Bounty programs.","PeriodicalId":33459,"journal":{"name":"Trudy Instituta sistemnogo programmirovaniia RAN","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81942500","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}
