Cybersecurity Approaches for Safeguarding Gis and Iot Systems in Smart Cities

Introduction: With the increasing growth of smart cities and the use of Geographic Information System (GIS) and Internet of Thinks (IoT) to enhance urban services, there is an urgent need for cybersecurity. The interconnected nature of smart city systems has become vulnerable to cyber threats. To secure data, encryption has become an urgent need to secure data at various stages during transmission, at static, and during data processing. Objectives: This study discusses data encryption and challenges using 2D vector distribution and encryption keys. Sensitive data coming from GIS systems and transmitted through IoT devices can be encrypted. Methods: In the context of smart cities supported by IoT and GPS, it is essential to maintain data security and integrity of its transmission as well. The information transmitted through the smart city network is of various types, including spatial information, infrastructure locations, sensor readings, and real-time communications such as transportation and environmental monitoring. All data is gathered in one context, which is the digital character, and is transmitted from the source to one of the communication layers, which is the transport layer, and then it takes a preliminary processing path through protocols and is transmitted to the physical layer. Results: The proposed method has proven its worth through good results in encryption evaluation criteria PSNR=86 dB, MSE=40, and Accuracy= 80%. Conclusions: The study emphasized the importance of real-time encryption given the rapid increase in smart city data. The study provides a comprehensive overview of how encryption works as a flexible foundation for cybersecurity in smart cities that support GIS and IoT systems, and to ensure data security amidst the acceleration of technological development.
