1 Secure firmware Over-The-Air updates for IoT: Survey, challenges, and discussions
به روز رسانی ایمن میان افزار خارج از هوا برای اینترنت اشیا: بررسی، چالش ها و بحث ها-2022
The Internet of Things (IoT) market has shown strong growth in recent years, where many manufacturers of IoT devices and IoT-related service providers are competing. Time to market has become essential to be competitive. The faster a competitor develops and integrates his product, the more likely he is to dominate the market. This competition could lead to critical security issues due to the lack of testing or the short development time. Moreover, lots of IoT devices present some vulnerabilities that can be exploited by attackers. They are also constantly subject to Zero-days, which require quick intervention to maintain the security of the environments in which they are deployed in. For these purposes, the quick update of the firmware image of these IoT devices is an effective way to counter most of these attacks. This document starts by defining the firmware update mechanisms for IoT, and in particular the ones done Over-The-Air. Then presents a state-of-the-art of the currently proposed solutions, with the particularity of surveying from the literature, the standardization bodies and from some well known industrial solutions. It also proposes a new classification of the different types of System on Chip (SoC) present in the marketed IoT devices together with an analysis of the different challenges and threats related to the OTA update. The objective is to open up the horizon for future research directions.

2 A framework for intelligent IoT firmware compliance testing
چارچوبی برای تست سازگاری سیستم عامل اینترنت اشیاء هوشمند-2022
The recent mass production and usage of the Internet of Things (IoT) have posed serious concerns due to the unavoidable security complications. The firmware of IoT systems is a critical component of IoT security. Although multiple organizations have released security guidelines, few IoT vendors are following these guidelines properly, either due to a lack of accountability or the availability of appropriate resources. Some tools for this purpose can use static, dynamic, or fuzzing techniques to test the security of IoT firmware, which may result in false positives or failure to discover vulnerabilities. Furthermore, the vast majority of resources are devoted to a single subject, such as networking protocols, web interfaces, or Internet of Things computer applications. This paper aims to present a novel method for conducting compliance testing and vulnerability evaluation on IoT system firmware, communication interfaces, and networking services using static and dynamic analysis. The proposed system detects a broad range of security bugs across a wide range of platforms and hardware architectures. To test and validate our prototype, we ran tests on 4300 firmware images and discovered 13,000þ compliance issues. This work, we believe, will be the first step toward developing a reliable automated compliance testing framework for the IoT manufacturing industry and other stakeholders.

3 Fog Node Self-Control Middleware: Enhancing context awareness towards autonomous decision making in Fog Colonies
میان افزار خودکنترلی گره مه: افزایش آگاهی از زمینه به سمت تصمیم گیری مستقل در کلونی های مه-2022
The concept of Fog Colonies has recently been introduced in Fog Computing, and is rapidly gaining attention. As Fog Colonies are extended, Fog Colony Control mechanisms have gained significant interest. Although, there are numerous solutions efficiently supporting a Context Aware coordinating entity, exploring approaches for decentralized control remains a challenge. Towards this direction, there are efforts promoting the concept of autonomous Fog Nodes, making their own decisions with internalized control without the existence of a coordinating entity. In this paper we propose and implement a Context Aware Self-Control management middleware for Fog Nodes, enabling their Self-Management utilizing contextual information shared between Fog colony members. To that end, we employ Policy Rulebooks to define Context Aware Policies that each Fog Node can enforce. Finally, we evaluated the proposed middleware against a non Context Aware one, under exactly the same conditions, using a real-world smart building use case, focusing on performance issues related to the end-user.

4 Toward a hardware man-in-the-middle attack on PCIe bus
به سوی حمله سخت افزاری در میان افزار شکاف PCIe -2020
The growing need for high rate communication of recent embedded systems is leading to the adoption of the PCIe protocol (Peripheral Component Interconnect express) as an internal data bus. This technology is used in some recent smartphones, and will probably be adopted globally in the next few years. The communication between the processor (in the SoC) and its memory through the PCIe bus represents an important source of information for criminal investigations. In this paper, we present a new attack vector on PCIe based on a hardware Man-in-the-Middle. This system allows real-time data analysis, data-replay, and a copy technique inspired by the shadow-copy principle. Through this one, it is possible to locate, duplicate, and replay sensitive data. The main challenge here is to develop an architecture compliant with PCIe protocol constraints, such as response time, frequency, and throughput, in order to be non-detectable to the communication parts. We designed a proof of concept of an emulator based on a computer with PCIe 3.0 bus and a Stratix 5 FPGA with an endpoint PCIe port as a development target.

6 Middleware technologies for cloud of things-a survey
تکنولوژی های میان افزار برای ابرهای اشیاء - یک مرور -2017
The next wave of communication and applications will rely on new services provided by the Internet of Things which is becoming an important aspect in human and machines future. IoT services are a key solution for providing smart environments in homes, buildings, and cities. In the era of massive number of connected things and objects with high growth rate, several challenges have been raised, such as management, aggregation, and storage for big produced data. To address some of these issues, cloud computing emerged to the IoT as Cloud of Things (CoT), which provides virtually unlimited cloud services to enhance the large-scale IoT platforms. There are several factors to be considered in the design and implementation of a CoT platform. One of the most important and challenging problems is the heterogeneity of different objects. This problem can be addressed by deploying a suitable “Middleware” which sits between things and applications as a reliable platform for communication among things with different interfaces, operating systems, and architectures. The main aim of this paper is to study the middleware technologies for CoT. Toward this end, we first present the main features and characteristics of middlewares. Next, we study different architecture styles and service domains. Then, we presents several middlewares that are suitable for CoT-based platforms and finally, a list of current challenges and issues in the design of CoT-based middlewares are discussed.

7 A mobile crowd sensing ecosystem enabled by CUPUS: Cloud-based publish/subscribe middleware for the Internet of Things
اکوسیستم سنجش شوغی سیار فعال شده توسط CUPUS: میان افزار پخش / اشتراک مبتنی بر ابر برای اینترنت اشیا-2016
Mobile crowd sensing (MCS) is a novel class of mobile Internet of Things (IoT) applications for community sensing where sensors and mobile devices jointly collect and share data of interest to observe phenomena over a large geographic area. The inherent device mobility and high sensing frequency has the capacity to produce dense and rich spatiotemporal information about our environment, but also creates new challenges due to device dynamicity and energy constraints, as well as large volumes of generated raw sensor data which need to be processed and analyzed to extract useful information for end users. The paper presents an ecosystem for mobile crowd sensing which relies on the CloUd-based PUblish/Subscribe middleware (CUPUS) to acquire sensor data from mobile devices in a flexible and energy-efficient manner and to perform near real-time processing of Big Data streams. CUPUS has unique features compared to other MCS platforms: It enables management of mobile sensor resources within the cloud, supports filtering and aggregation of sensor data on mobile devices prior to its transmission into the cloud based on global data requirements, and can push information of interest from the cloud to user devices in near real-time. We present our experience with implementation and deployment of an MCS application for air quality monitoring built on top of the CUPUS middleware. Our experimental evaluation shows that CUPUS offers scalable processing performance, both on mobile devices and within the cloud, while its data propagation delay is mainly affected by transmission delay on wireless links.

9 Engineering Future Internet applications: The Prime approach
آینده مهندسی برنامه های کاربردی اینترنت: رویکرد اولیه-2015
Article history:Received 23 June 2014Revised 30 March 2015Accepted 31 March 2015Available online 14 April 2015Keywords:Resource-oriented architecture MiddlewareFuture InternetThe Future Internet is envisioned as a worldwide environment connecting a large open-ended collection of heterogeneous and autonomous resources, namely Things, Services and Contents, which interact with each other anywhere and anytime. Applications will possibly emerge dynamically as opportunistic aggregation of resources available at a given time, and will be able to self-adapt according to the environment dynamics. In this context, engineers should be provided with proper modeling and programming abstractions to develop applications able to benefit from Future Internet, by being at the same time fluid, as well as dependable. Indeed, such abstractions should (i) facilitate the development of autonomous and independent interacting resources (loose coupling), (ii) deal with the run-time variability of the application in terms of involved resources (flexibility), (iii) provide mechanisms for run-time resources discovery and access (dynamism), and(iv) enable the running application to accommodate unforeseen resources (serendipity).To this end, Prime (P-Rest at design/run tIME) defines the P-REST architectural style, and a set of P-REST oriented modeling and programming abstractions to provide engineers with both design-time and run-time support for specifying, implementing and operating P-RESTful applications.© 2015 Elsevier Inc.
