| چکیده | ||
| اینترنت اشیا (IoT) با فراهمسازی بستری برای ارتباط خودکار بین میلیونها دستگاه هوشمند، به یکی از زیرساختهای حیاتی دنیای مدرن دبل شده است. با افزایش چشمگیر تنوع، مقیاس و تحرکپذیری این دستگاهها، آسیبپذیریهای امنیتی نیز بهطور فزایندهای تشدید شدهاند. بهویژه، تهدیدات پنهان و پیچیدهای که از طریق الگوهای رفتاری غیرمعمول در شبکه پدید میآیند، ضرورت بهرهگیری از روشهای پیشرفتهی تشخیص ناهنجاری را دوچندان نموده است. در این پژوهش، مدلی نوین با بهرهگیری از رویکرد یادگیری گروهی ارائه گردیده که ترکیبی از تکنیکهای یادگیری عمیق و الگوریتمهای کلاسیک یادگیری ماشین را به کار گرفته است. پس از انجام پیشپردازش دادهها، ویژگیهای کلیدی از طریق رمزگذار خودکار پشتهای (SAE) و رمزگذار خودکار عمیق (DAE) استخراج شدهاند. در ادامه، یک چارچوب یادگیری گروهی متشکل از درخت تصمیم (DT)، پرسپترون چندلایه (MLP)، شبکه عصبی احتمالی (PNN) و نوع وزنی آن (WPNN) برای شناسایی ناهنجاریها مورد استفاده قرار گرفته است.از نوآوریهای این تحقیق میتوان به طراحی یک سازوکار انتخاب پویای ویژگی در لایه رمزگذار و همچنین پیشنهاد یک طرح وزندهی تطبیقی برای ترکیب خروجی مدلهای گروهی اشاره کرد، که موجب بهبود دقت در تشخیص حملات ناشناخته و کاهش نرخ مثبت کاذب شده است. مدل پیشنهادی بر روی چندین مجموعهداده معتبر از جمله NSL-KDD، BoT-IoT، IoT-NI، IoT-23، MQTT، MQTTset و IoT-DS2 ارزیابی شده و نتایج بهبود عملکرد قابلتوجهی را در مقایسه با مدلهای مرجع نشان دادهاند. | ||

| چکیده [English] | ||
| The Internet of Things (IoT), by providing a platform for automatic communication among millions of smart devices, has become one of the critical infrastructures of the modern world. With the dramatic increase in the diversity, scale, and mobility of these devices, security vulnerabilities have also escalated significantly. In particular, hidden and sophisticated threats emerging through unusual behavioral patterns in the network have underscored the necessity for advanced anomaly detection methods. In this research, a novel model utilizing an ensemble learning approach is presented, combining deep learning techniques with classical machine learning algorithms. After data preprocessing, key features are extracted using Stacked Autoencoder (SAE) and Deep Autoencoder (DAE). Subsequently, an ensemble framework composed of Decision Tree (DT), Multilayer Perceptron (MLP), Probabilistic Neural Network (PNN), and its weighted variant (WPNN) is employed for anomaly detection. Innovations in this study include the design of a dynamic feature selection mechanism within the encoder layer and the proposal of an adaptive weighting scheme for aggregating ensemble model outputs, which enhance the accuracy of detecting unknown attacks and reduce the false positive rate. The proposed model has been evaluated on several reputable datasets including NSL-KDD, BoT-IoT, IoT-NI, IoT-23, MQTT, MQTTset, and IoT-DS2, demonstrating significant performance improvements compared to baseline models | ||
