Shraiyash Pandey, Bharat Bhushan · 2023
Smart cities have evolved into a new model that provides a better quality of life, and efficiently optimizes the resources in the city to provide improved facilities. However, despite the evolution of smart cities, privacy and security challenges are a concern that needs to be addressed. Therefore, in this paper, we thoroughly explore the complications that arise in the protection of data in smart cities, and the various lightweight cryptographic algorithms available that can be implemented as a viable and feasible solution. Smart cities are immensely equipped with IoT devices, therefore we present various accessible methods to protect the data of IoT devices, which indirectly results in the protection of data in smart cities. The paper aims to provide various lightweight cryptographic algorithms and methods available that are suitable for the security of smart cities. Moreover, explain the challenges towards the implementation of each algorithm to exploit all challenges of smart city security. Each algorithm provides a certain level of security in its own manner, however, no algorithm can be defined as ideal and perfect for all types of cyberattacks, so we present a comparison among various algorithms that can be implemented. Further, we present a list of recent advancements in the security of smart cities to provide extensive information on recent innovations, new security models, new communication protocols, new authentication schemes, etc. which are all under the same domain of security of smart cities.
