A Survey on Standards for Interoperability and Security in the Internet of Things

Abstract

Recently, there has been an increase in studies relating to the Internet of Things (IoT) in various fields, such as smart cities, smart homes, smart factories, and healthcare. In an IoT environment, several entities, including users, devices, and information resources, are interconnected and interworked with services. Therefore, interoperability between different entities is essential to accomplish the goals of IoT systems. Further, security is another important aspect to achieve in an IoT environment to protect information resources and privacy when networking between different entities. Therefore, security and interoperability may be significant barriers in the implementation of IoT in the real world. Several studies have been conducted to investigate methods for accomplishing interoperability and security in IoT, but they address only specific problems. Hence, compatibility and generality must be considered to accomplish the goals of IoT systems. International standards provide general methods by listing protocols, rules, guidelines, and characteristics that are defined and approved by authorized organizations, helping develop and manage systems efficiently by applying these standards; interoperability and security are supported by adopting standards in development and management. Therefore, the adoption of international standards is required to overcome the barriers in IoT. Furthermore, international standard organizations are developing IoT-related standards that may provide a solution to interoperability and security. However, a study focusing on interoperability- and security-related standards has not yet been conducted. Therefore, in this paper, we focus on international standards related to interoperability and security for IoT environments. Moreover, we studied international standard organizations that have been developing standards for IoT. In this study, a systematic literature review is conducted, and international standards are analyzed. In addition, any remaining challenges related to interoperability and security for IoT standards are discussed.
