The Internet of Things (IoT) technologies, a wide variety of network devices will be able to communicate with one another independently of their own local networks and resource capacity. When it comes to the growth of the Internet of Things, one of the most important concerns is the protection of end-user privacy, communication, and security. It is of the utmost importance to provide secure communication in a wide range of applications, especially in situations when communication devices have limited resources. The advent of the Internet of Things necessitates, among other things, the use of low-power devices that link with one another in order to perform important processing. Even if these devices have limited capabilities and resources, it is projected that they will be able to handle significant amounts of data pertaining to monitoring and control situations. Using the secure encryption technique, vulnerable devices should be protected from potential threats. As a consequence of this, the Internet of Things has been plagued by a multitude of significant problems about trust and security. As a potential solution to these problems, the unique method known as SPrimeBR has been proposed as a suggestion. The suggested technique is comprised of four different steps. In the first step of the procedure, the plain text (PT) representation of the secret key is used. This is the second phase, which entails converting the PT code to the ASCII code. Choosing the prime number and incorporating it into Eq. 1 is the third phase in the process. During the fourth phase, row operations are carried out. It is necessary to encrypt plain text in order to ensure the confidentiality of the information. The act of reversing this conversion is known as decryption, and it is what ultimately results in the message being obtained in its initial form. A higher degree of security is provided by the solution that has been proposed, in comparison to encryption approaches that are more conventional.
