Secure Authentication for Unified Software Architecture for Smart Computing IoT devices through Mobile App

Abstract

IoT devices play a significant part in the connectivity of everything to the internet in this century, making it possible for users to effortlessly access and control their gadgets from a distant location. The primary benefit of using Internet of Things devices is the ability to save time, have remote access to resources at any time and from any location, and have everything linked to the internet. Since its inception, the Internet of Things (IoT) industry has been plagued by a number of problems, most of which are concerned with data protection and security. Confidentiality and integrity both play an important part in the authentication process for security, which is necessary in order to create a robust security system. At this time, Internet of Things protocols also offer various levels of security, all of which are connected in some way to authentication and authorization. However, as time goes on, it will become increasingly important that the level of protection against various attacks, such as masquerade attacks, man-in-the-middle attacks, replay attacks, password guessing Impounder attacks, DoS attacks, and so on, requires more protection at different layers. We used a temperature sensor (DHT22) with Node MCU in this research to investigate security and develop a smart solution. We propagated data over the Internet of Things protocol and received it at the Mobile end. In this study, we examine the safe transmission of data from the Internet of Things devices to mobile devices and highlight the problems we faced and overcame while constructing the prototype. Additionally, we are concentrating on the level of security involved in the transmission of data from the Internet of Things devices to the cloud as well as from the cloud to mobile devices directly, and we are developing a prototype that is capable of operating flawlessly and that propagates data smoothly to the cloud.
