چکیده

با تکامل شبکه بی‌سیم نسل پنجم، اینترنت اشیا (IOT) نیز تحول شگفتی در زندگی بشر ایجاد کرده است. از اینرو مطالعه دقیق‌تر فناوری اینترنت اشیا و حوزه‌های مختلف آن از جمله امنیت این حوزه ضروری خواهد بود. در زمینه امنیت شبکه‌های اینترنت اشیا، یکی از مواردی که مطرح شده انتشار بدافزار است. در این مقاله به مدل‌سازی انتشار بدافزار در شبکه‌های اینترنت اشیا با مدل بیماری‌های همه‌گیری آسیب‌پذیر – در معرض آلودگی - آلوده - بهبودیافته - پادزهر پرداخته‌ایم. اثر اعمال پادزهر روی گره‌های بهبودیافته و آسیب‌پذیر، در انتشار بدافزار شبکه‌های اینترنت اشیا مورد بررسی قرار گرفته است. ما بر اساس درجه گره میزان با اهمیت بودن گره را در شبکه تعیین کرده‌ایم و بر اساس این نرخ، گره‌های آسیب‌پذیر در شبکه ایمن شده‌اند. ایمن‌سازی گره‌های آسیب‌پذیر بر مبنای درجه منجر به کاهش انتشار بدافزار در شبکه شده است. حد آستانه اپیدمی انتشار بدفزار (R₀) در مدل پیشنهادی محاسبه شده است. مقایسه مدل با دو مدل SIRS و SEIRS نشان داد مدل پیشنهادی نسبت به دو مدل دیگر عملکرد بهتری داشته است.

چکیده [English]

With the evolution of the fifth generation wireless network, the Internet of Things (IoT) has also created a surprising transformation in human life. Therefore, a more detailed study of IoT technology and its various fields, including security, is necessary. In the field of IoT network security, one of the issues that has been raised is the spread of malware. In this paper, we have modeled the spread of malware in IoT networks with the epidemic disease model of vulnerable - exposed to infection - infected - recovered - antidote. The effect of applying antidote to recovered and vulnerable nodes on the spread of malware in IoT networks has been investigated. We have determined the importance of the node in the network based on its degree, and based on this rate, the vulnerable nodes in the network have been secured. Securing nodes based on the degree has led to a reduction in the spread of malware in the network. The epidemic threshold of malware spread (R₀) has been calculated in the proposed model. Comparing the model with the SIRS and SEIRS models showed that the proposed model performed better than the other two models.
