Due to tremendous technological improvements, over the past several years the world has witnessed, and continues to witness, digitalization, which has received a wealth of attention. Technology and connectivity have made it possible for many technologies and pieces of software to be connected, which has subsequently made it possible to communicate without a human being directly involved. The internet of things (IoT) is a phenomenon that has gained much popularity since its inception in 2009 and which has become a crucial component in real-life applications. In order to understand how the internet of things (IoT) might be used to improve the many aspects of the public sector, as well as its limits, this paper explores the many definitions of IoT in relation to its use in the public sector and focuses on designing a new framework that can be used as a guideline of using IoT in public sectors in diverse international contexts. 

A New Internet of Things (IoT) Framework for Public Sectors

Due to tremendous technological improvements, over the past several years the world has witnessed, and continues to witness, digitalization, which has received a wealth of attention. Technology and connectivity have made it possible for many technologies and pieces of software to be connected, which has subsequently made it possible to communicate without a human being directly involved. The internet of things (IoT) is a phenomenon that has gained much popularity since its inception in 2009 and which has become a crucial component in real-life applications. In order to understand how the internet of things (IoT) might be used to improve the many aspects of the public sector, as well as its limits, this paper explores the many definitions of IoT in relation to its use in the public sector and focuses on designing a new framework that can be used as a guideline of using IoT in public sectors in diverse international contexts.

With the ever-increasing use of large-scale IoT networks in different sectors of the industry, it has become critical to realise seamless and secure communication between devices in the network. Realising secure group communication in the IoT requires solving the problem of group-key establishment. In this work, we solve the problem by designing a new lattice-based Key Encapsulation Mechanism (KEM) for resource-constrained devices that enable the distribution of a symmetric key or any other data between all the devices in a given network. This is achieved by coupling multiple private keys to a unique public key. Moreover, we present a proof-of-concept implementation based on the GGH algorithm. The results show it is feasible to use lattice-based cryptography to allow for seamless and secure group communications within a decentralised IoT network. It has been bench-marked against other common post-quantum constructs and proven to be more practical with respect to memory consumption and security, although considerably slower due to lack of optimisation in the implementation.
