A community‐based hierarchical user authentication scheme for Industry 4.0

Abstract

Summary The vision of Industry 4.0 is characterized by the amalgamation of cyber‐physical systems and industrial Internet of Things. Such a complex ecosystem urges for the requirement of novel security protocol and mechanisms for access control so as to allow the smart devices to authorize external entities and granting them access rights without depending on centralized authentication entities. The work proposed in this article aims to utilize a community‐based hierarchical approach to define the procedure for obtaining access rights in the Industry 4.0 ecosystem. The proposed scheme considers a hierarchy of authorizing devices that work in collaboration for providing access control of the smart end devices to the users. The adoption of hierarchical structure ensures that the access rights are eventually given to only those users that have passed multiple levels of successful authorization. The proposed scheme also combats any infringement of users identity since the authorizing entities involved in the proposed system work in close collaboration for user authentication. The proposed user authentication scheme has been validated using burrows‐abadi‐needham (BAN)‐logic and is proved to be secure against a variety of security attacks.

On Analysis of Security and Elasticity Dependency in IIoT Platform Services

“…That is, they are able to only monitor and test the elasticity of infrastructure (such as VM) and not an individual platform service. Security of IIoT platform services elasticity: While there are multiple literatures that address security in edge and cloud subsystems [22], [23]; there exists little literature that attempt to perform a holistic analysis of the IIoT infrastructure and study the underlying dependence with respect to security attack and elasticity impacts. STRATFram [24] framework allows the users to specify elasticity models and evaluates the elasticity strategies on the cloud.…”

SDN-Enabled Content Dissemination Scheme for the Internet of Vehicles

“…An in-depth understanding of the fundamental content of the applications before forwarding the information in the IoV network is of utmost significance. However, the core network procedures are still dependent upon address-content binding even with several advancements in the communication paradigms [8,9]. In case a user wants to request data, it is required to provide the media access control address as well as the internet protocol address (MAC/IP address) of the node from which the data is to be taken.…”

The Development of Mobile Application Security Through Encryption

“…It is likely to fall into the hands of adversaries who will exploit cryptographic tools to decrypt the data. In addition, security issues occur due to how users commonly take authorization and authentication for granted when designing their systems (Almaiah et al, 2022;Sinha et al, 2022). In particular, in terms of mobile devices, authentication can play a significant influence in reducing and mitigating several unauthorized access and data breaches (Ullah et al, 2019).…”
