Fog Computing and Blockchain for Massive IoT Deployment

Abstract: The expected exponential growth of IoT devices in future years arises management issues to be resolved. Cloud computing may not be adequate for a massive scale while fog computing brings the ability to manage the distribution of controllability and manageability. Besides, such decentralized architecture is not sufficient to handle sensitive transactions, blockchain-based technology has raised hypes in implementing applications in trust-less environments. This paper proposes a blockchain-based architecture for scalable control of IoT devices. Moreover, smart contracts are developed to facilitate the ledger update process. Experimental results show that the proposed architecture is capable of providing trust on-demand changes with a negligible effect on IoT resources.

Abstract: Many industrials consider blockchain as a technology breakthrough for cybersecurity, with use cases ranging from cryptocurrency system to smart contracts, and so forth. While IoT systems employ a lightweight communication protocol between physical objects, blockchain may ensure safe information gathering. Unfortunately, the mixture of both technologies has yet to be formally investigated regarding the consensus algorithm. In this paper, statistical model checking is applied to provide quantitative answers on whether the modeled system satisfies safety and liveness properties expressed in LTL temporal logic.

Applied Statistical Model Checking for a Sensor Behavior Analysis

Abstract: The analysis of sensors’ behavior becomes one of the essential challenges due to the growing use of these sensors for making a decision in IoT systems. The paper proposes an approach for a formal specification and analysis of such behavior starting from existing sensor traces. A model that embodies the sensor measurements over the time in the form of stochastic automata is built, then temporal properties are feed to Statistical Model Checker to simulate the learned model and to perform analysis. LTL properties are employed to predict sensors’ readings in time and to check the conformity of sensed data with the sensor traces in order to detect any abnormal behavior.

Exploration of Impactful Countermeasures on IoT Attacks

Abstract:

Risks mitigation in IoT based systems is one of the recent challenges in both academia and industry. In this work, we propose an approach based on the attack-defense tree to assess the relevant countermeasures for protecting IoT infrastructure.

To this end, an attack strategy exploration tool built on the top of the statistical model checker and genetic algorithm is used to select high impactful countermeasures. From that result, defense strategies are highlighted while a compromise guarantee between successful attacks, the cost incurred and the time to perform a sequence of attack actions. We report experiments applied over IoT network attacks.

Abstract:

While the number of digital services is increasing faster and faster, those services rely more and more on IoT systems to collect data and perform data analysis, eventually using AI techniques. In this context, devices are part of the “root of trust” and need to be secured in order to ensure high quality and trusted digital services.

This paper presents an approach to facilitate the integration, verification and then the functional validation of the security into devices based on modeling and simulation. This approach allows reducing the cost impact of adding security layer to physical devices.

BRAIN-IoT: Paving The Way For Next-Generation Internet of Things

Abstract: Nowadays, the adoption of the Internet of Things is drastically increasing in different domains and is contributing to the fast digitalization of several different critical sectors. In the near future, next generation of IoT-based systems will become more complex to be designed and managed. An opportunity for the development of flexible smart IoT-based systems that drive the business decision-making is to take more precise and accurate decisions at the right time, collecting real-time IoT generated data. This involves a set of challenges including the complexity of IoT-based systems and the management of large-scale systems scalability. With respect to these challenges, we propose to automate the management of IoT-based systems mainly based on an autonomic computing approach; these systems should implement cognitive capabilities that allow them learning and generating decisions at the right time. Consequently, we propose a model-driven methodology for designing smart IoT-based systems…

Privacy awareness for IoT platforms: BRAIN-IoT approach
  • Authors: Mohammad Rifat Ahmmad RASHID, Davide CONZON, Xu TAO and Enrico FERRERA
  • Published in: the book “Security and Privacy in Internet of Things: Challenges and Solutions”
  • Pages: 24 – 43

Abstract:
With the increasing adaptation of Internet of Things (IoT) platforms in decentralized cloud environments, more focus given towards facilitating the privacy awareness building upon goals set by current European Union (EU) General Data Protection Regulation (GDPR) regulations. Therefore, it is necessary to empower the end users (both private and corporate) of IoT platforms with the capability of deciding which combination of self-hosted or cloud-oriented IoT systems are most suitable to handle the personal data they generate and own as well as with the ability to change the existing (or pre-set) configurations at any time. Furthermore, adaptation of GDPR regulations in IoT platforms is challenging as there are needs for significant efforts to integrate privacy policies in a programmatic way to: (i) increase awareness of users about which data is collected, where it is transmitted, by whom, etc.; (ii) provide controls to enable users to notify such aspects, being at the same time aware of how such a decision affects the quality of the IoT services provided in that IoT platform. BRAIN-IoT project focuses on complex scenarios where actuation and control are cooperatively supported by populations of IoT systems. The breakthrough targeted by BRAIN-IoT is to provide solutions to embed privacy-awareness and privacy control features in IoT solutions. In this work, the authors explore the following key areas: (a) privacy awareness in IoT systems using GDPR regulations and BRAIN-IoT platform, and (b) propose a conceptual framework for Privacy Impact Assessment (PIA) using privacy principles presented in GDPR regulations. The proposed privacy awareness framework is cross-platform, so it is suitable to support a wide number of heterogeneous IoT systems, deployed by corporate and private users.

Abstract:

Modern applications in the Smart Building and Industry 4.0 scenarios will be complex software ecosystems with strict requirements of geographic distribution, heterogeneity, dynamic evolution, security and privacy protection, highly more challenging than the ones required by the current environments. Two of the main challenges arising in the current Internet Of Things scenarios, i.e., the Smart Building one, are, on one side, the requirement of interconnecting several heterogeneous platforms and smart Things in the same environment and, on the other side, the need to be able to evolve the complex software ecosystem deployed, reacting automatically and at runtime to environmental changes, without the human intervention. To address these challenges, BRAIN-IoT establishes a framework and methodology supporting smart cooperative behaviour in fully de-centralized, composable and dynamic federations of heterogeneous Internet of Things platforms. In this way, BRAIN-IoT enables smart autonomous behaviour in Internet of Things scenarios, involving heterogeneous sensors and actuators autonomously cooperating to execute complex, dynamic tasks. Furthermore, BRAIN-IoT enables dynamically deploying and orchestrating distributed applications, allowing the automatic installation and replacement of smart behaviours reacting to environmental changes and User events. Finally, BRAIN-IoT provides a set of components that guarantee the security and privacy protection of the data exchanged using the solution. BRAIN-IoT is a general purpose solution that aims at being adaptable for heterogeneous scenarios, from Service Robotics to Critical Infrastructure Management. This paper introduces a Smart Building use case of the solution, which allows highlighting the advantages given by BRAIN-IoT in such scenario.

Source: https://ieeexplore.ieee.org/document/8903975

The next generation of Smart City and Industry 4.0 applications will be geographically distributed, heterogeneous, co-evolving software ecosystems, significantly more sophisticated than the current Enterprise or Cloud compute environments. To be economically sustainable and achieve solution longevity, these software ecosystems must be operationally simple, cost effective to maintain over extended periods of time, and able to cost effectively adapt to both changing environmental conditions and service requirements. This paper presents the BRAIN-IoT Federation, a distributed and highly modular federated environment that addresses these sustainability, longevity and adaptability challenges by leveraging OSGi – the Open Standard for Software Modularity. With a focus on Operational simplicity, BRAIN-IoT federation enables the dynamic deployment, orchestration and monitoring of distributed applications and uniquely, automatically installing new behaviours in response to environment triggers and User events. To show how, through the use of OSGi components and standards, it is possible to build a software solution able to address all the challenges presented by the modern scenarios, in terms of agility and adaptability, this work presents an use case study related to the use of robots for last-mile delivery of parcels. Over the next few years this field promises to provide high cost savings and reduction of the environmental impact, allowing to reduce the traffic caused by parcels delivering. An exploration of how the BRAIN-IoT federation is applicable to such environment, enabling robots adapt to changing and diverse Internet of Things environments, will be presented in the paper.
