Access Management in Lightweight IoT: A Comprehensive review of ACE-OAuth framework
With the expansion of Internet of Things (IoT), the need for secure and scalable authentication and
authorization mechanism for resource-constrained devices is becoming increasingly important. This
thesis reviews the authentication and authorization mechanisms in resource-constrained Internet of
Things (IoT) environments. The thesis focuses on the ACE-OAuth framework, which is a lightweight
and scalable solution for access management in IoT. Traditional access management protocols are not
well-suited for the resource-constrained environment of IoT devices. This makes the lightweight
devices vulnerable to cyber-attacks and unauthorized access. This thesis explores the security
mechanisms and standards, the protocol flow and comparison of ACE-OAuth profiles. It underlines
their potential risks involved with the implementation. The thesis delves into the existing and
emerging trends technologies of resource-constrained IoT and identifies limitations and potential
threats in existing authentication and authorization methods.
Furthermore, comparative analysis of ACE profiles demonstrated that the DTLS profile enables
constrained servers to effectively handle client authentication and authorization. The OSCORE
provides enhanced security and non-repudiation due to the Proof-of-Possession (PoP) mechanism,
requiring client to prove the possession of cryptographic key to generate the access token.
The key findings in this thesis, including security implications, strengths, and weaknesses for ACE
OAuth profiles are covered in-depth. It shows that the ACE-OAuth framework’s strengths lie in its
customization capabilities and scalability. This thesis demonstrates the practical applications and
benefits of ACE-OAuth framework in diverse IoT deployments through implementation in smart
home and factory use cases. Through these discussions, the research advances the application of
authentication and authorization mechanisms and provides practical insights into overcoming the
challenges in constrained IoT settings
Recent advances in industrial wireless sensor networks towards efficient management in IoT
With the accelerated development of Internet-of- Things (IoT), wireless sensor networks (WSN) are gaining importance in the continued advancement of information and communication technologies, and have been connected and integrated with Internet in vast industrial applications. However, given the fact that most wireless sensor devices are resource constrained and operate on batteries, the communication overhead and power consumption are therefore important issues for wireless sensor networks design. In order to efficiently manage these wireless sensor devices in a unified manner, the industrial authorities should be able to provide a network infrastructure supporting various WSN applications and services that facilitate the management of sensor-equipped real-world entities. This paper presents an overview of industrial ecosystem, technical architecture, industrial device management standards and our latest research activity in developing a WSN management system. The key approach to enable efficient and reliable management of WSN within such an infrastructure is a cross layer design of lightweight and cloud-based RESTful web service
Integration of heterogeneous devices and communication models via the cloud in the constrained internet of things
As the Internet of Things continues to expand in the coming years, the need for services that span multiple IoT application domains will continue to increase in order to realize the efficiency gains promised by the IoT. Today, however, service developers looking to add value on top of existing IoT systems are faced with very heterogeneous devices and systems. These systems implement a wide variety of network connectivity options, protocols (proprietary or standards-based), and communication methods all of which are unknown to a service developer that is new to the IoT. Even within one IoT standard, a device typically has multiple options for communicating with others. In order to alleviate service developers from these concerns, this paper presents a cloud-based platform for integrating heterogeneous constrained IoT devices and communication models into services. Our evaluation shows that the impact of our approach on the operation of constrained devices is minimal while providing a tangible benefit in service integration of low-resource IoT devices. A proof of concept demonstrates the latter by means of a control and management dashboard for constrained devices that was implemented on top of the presented platform. The results of our work enable service developers to more easily implement and deploy services that span a wide variety of IoT application domains
CoAP over ICN
The Constrained Application Protocol (CoAP) is a specialized Web transfer
protocol for resource-oriented applications intended to run on constrained
devices, typically part of the Internet of Things. In this paper we leverage
Information-Centric Networking (ICN), deployed within the domain of a network
provider that interconnects, in addition to other terminals, CoAP endpoints in
order to provide enhanced CoAP services. We present various CoAP-specific
communication scenarios and discuss how ICN can provide benefits to both
network providers and CoAP applications, even though the latter are not aware
of the existence of ICN. In particular, the use of ICN results in smaller state
management complexity at CoAP endpoints, simpler implementation at CoAP
endpoints, and less communication overhead in the network.Comment: Proc. of the 8th IFIP International Conference on New Technologies,

Memory Management Strategies for an Internet of Things System
The rise of the Internet has brought about significant changes in our lives,
and the rapid expansion of the Internet of Things (IoT) is poised to have an
even more substantial impact by connecting a wide range of devices across
various application domains. IoT devices, especially low-end ones, are
constrained by limited memory and processing capabilities, necessitating
efficient memory management within IoT operating systems. This paper delves
into the importance of memory management in IoT systems, with a primary focus
on the design and configuration of such systems, as well as the scalability and
performance of scene management. Effective memory management is critical for
optimizing resource usage, responsiveness, and adaptability as the IoT
ecosystem continues to grow. The study offers insights into memory allocation,
scene execution, memory reduction, and system scalability within the context of
an IoT system, ultimately highlighting the vital role that memory management
plays in facilitating a seamless and efficient IoT experience.Comment: International Symposium on Fundamentals of Electrical Engineering

A Survey on Resource Management in IoT Operating Systems
Recently, the Internet of Things (IoT) concept has attracted a lot of attention due to its capability to translate our physical world into a digital cyber world with meaningful information. The IoT devices are smaller in size, sheer in number, contain less memory, use less energy, and have more computational capabilities. These scarce resources for IoT devices are powered by small operating systems (OSs) that are specially designed to support the IoT devices' diverse applications and operational requirements. These IoT OSs are responsible for managing the constrained resources of IoT devices efficiently and in a timely manner. In this paper, discussions on IoT devices and OS resource management are provided. In detail, the resource management mechanisms of the state-of-the-art IoT OSs, such as Contiki, TinyOS, and FreeRTOS, are investigated. The different dimensions of their resource management approaches (including process management, memory management, energy management, communication management, and file management) are studied, and their advantages and limitations are highlighted
New Paradigms for Access Control in Constrained Environments
International audienceThe Internet of Things (IoT) is here, more than 10 billion units are already connected and five times more devices are expected to be deployed in the next five years. Technological standarization and the management and fostering of rapid innovation by governments are among the main challenges of the IoT. However, security and privacy are the key to make the IoT reliable and trusted. Security mechanisms for the IoT should provide features such as scalability, interoperability and lightness. This paper adresses authentication and access control in the frame of the IoT. It presents Physical Unclonable Functions (PUF), which can provide cheap, secure, tamper-proof secret keys to authentify constrained M2M devices. To be successfully used in the IoT context, this technology needs to be embedded in a standardized identity and access management framework. On the other hand, Embedded Subscriber Identity Module (eSIM) can provide cellular connectivity with scalability, interoperability and standard compliant security protocols. The paper discusses an authorization scheme for a constrained resource server taking advantage of PUF and eSIM features. Concrete IoT uses cases are discussed (SCADA and building automation)
The Meeting of Acquaintances: A Cost-efficient Authentication Scheme for Light-weight Objects with Transient Trust Level and Plurality Approach
Wireless sensor networks consist of a large number of distributed sensor
nodes so that potential risks are becoming more and more unpredictable. The new
entrants pose the potential risks when they move into the secure zone. To build
a door wall that provides safe and secured for the system, many recent research
works applied the initial authentication process. However, the majority of the
previous articles only focused on the Central Authority (CA) since this leads
to an increase in the computation cost and energy consumption for the specific
cases on the Internet of Things (IoT). Hence, in this article, we will lessen
the importance of these third parties through proposing an enhanced
authentication mechanism that includes key management and evaluation based on
the past interactions to assist the objects joining a secured area without any
nearby CA. We refer to a mobility dataset from CRAWDAD collected at the
University Politehnica of Bucharest and rebuild into a new random dataset
larger than the old one. The new one is an input for a simulated authenticating
algorithm to observe the communication cost and resource usage of devices. Our
proposal helps the authenticating flexible, being strict with unknown devices
into the secured zone. The threshold of maximum friends can modify based on the
optimization of the symmetric-key algorithm to diminish communication costs
(our experimental results compare to previous schemes less than 2000 bits) and
raise flexibility in resource-constrained environments.Comment: 27 page

the objects of our surroundings to intercommunicate with each
other in diverse working environments by utilizing their embedded
architectural and communication technologies. IoT has
provided humans the capability to manipulate the operations
and data available from different information systems using these
intelligent objects available in the surroundings. The scope of IoT
is to serve humanity across different domains of life covering industrial,
health, home and day-to-day operations of Information
Systems (IS). Due to the huge number of heterogeneous network
elements interacting and working under IoT based information
systems, there is an enormous need for resource management
for the smooth running of IoT operations. The key aspect in
IoT implementations is to have resource-constrained embedded
devices and objects participating in IoT operations. It is important
to meet the challenges raised during management and
sharing of resources in IoT based information systems. Managing
resources by implementing protocols, algorithms and techniques
are required to enhance the scalability, reliability and stability in
IoT operations across different fields of technology. This special
issue opens the new areas of interest for the researchers in the
domain of resource management in IoT operations
