A Brief Literature Survey on Cryptography Models for Detection of Cyber Attacks in Internet of Things Enabled Smart Cities

Improved infrastructure, more efficient public services, and improved transit systems are all ways in which smart cities use the Internet of Things (IoT) to raise the standard of living for their residents. It is imperative that processes be put in place to meet the varied needs of the use cases as IoT-enabled smart city applications gain popularity. The likelihood of cyber assaults and breaches is rising in tandem with the proliferation of linked gadgets. In order to prevent assaults that could damage citizens and institutions, it is essential to secure these systems. But protecting the IoT environment is no easy task. As smart city infrastructures incorporate more and more IoT devices, there is a pressing need for strong cybersecurity protocols. The safety and efficiency of urban systems are at risk since these devices are open to a variety of cyberattacks. In order to detect outliers brought about by cyberattacks on the IoT in smart cities, this research analyzes numerous cryptography models that provide security to IoT enabled smart gadgets. Improving the security of IoT networks while also protecting user data is a double challenge that the analyzed approached tackles. The need to ensure the secure and dependable functioning of Internet-connected devices is growing in tandem with the quantity of these devices. For the purpose of securing data transmissions on the ever-expanding network of sensors, this research focuses on cryptographic algorithms that can be included in IoT devices. In this paper, the issues of security on networked devices are considered and go over the primary procedures and algorithms that make this technology safe. Because our reliance on the internet of things grows daily, it is important to think about how to improve security-related technologies and algorithms.
