Security Issues in IoT and their Countermeasures in Smart City Applications

Abstract

Smart city can be taken as the biggest implementation of Internet of things (IoT) applications. Smart city technologies promote cloud-based and IoT-based services in which real-world user interfaces use smart phones, sensors, RFIDs, etc. The IoT ecosystems cannot properly communicate between them. So it needs a bridge between them to fill the global common approach. Implementation of this can be done with the help of information and communication technologies (ICT) which may result in enhancing quality, interconnection, and the performance of various urban services. It highlights the need for cloud computing and IoT technologies and both have a major impact on how we build and deploy smart applications for it. There are still numerous difficulties that remain with regard to its deployment due to its varying requirements. In this paper, authors tried to converge the two domains that are cloud computing and IoT for smart city application deployment and also present the identified security threat types and their countermeasures in the context of smart city.
