Towards Trustworthy Urbanization: Security and Privacy Objectives for Sustainable Smart City

Cities are now transforming from digital cities to smart cities which are more oriented towards technology and sustainability. When a city is interconnected, adaptive, autonomous, sustainable, and robust, it is called a “smart” city. The integration of big data and interconnected devices with a rapidly growing population leads toward the establishment of smart cities. As the population grows and resources get scarce, efficient utilization becomes important. By 2025, the world population is projected to increase to 8 billion and IoT devices are projected to increase to 80 billion, with a 1:10 person to device ratio! Smart cities help to improve daily life and encourage sustainable development to improve the functionality of tasks. As cities worldwide pursue sustainable smart city initiatives to improve environmental sustainability, efficiency, and quality of life for citizens, ensuring strong security and privacy safeguards remains an utmost priority on this pathway. However, innovation cannot overlook the aspect of security and privacy threats while implementing. Rudimentary security mechanisms may not complement the bloom of technology. In this paper, we discuss the smart city components along with the associated threats. Also, we redefined the security and privacy objectives in light of the requirement of sustainable smart cities.
