An innovative approach to the design of heterogeneous and distributed systems as an environment for ubiquitous computing services is presented by the Internet of Things (IoT). Because there are not enough processing and storage resources to handle the massive amounts of data generated by the Internet of Things (IoT), an architecture that is based on the cloud is being used extensively to address these requirements. Because of this, the cloud-based Internet of Things ecosystem has been plagued with a multitude of significant security and trust issues. In order to find solutions to these issues, a fresh strategy known as RB-25-2 has been proposed. There are a total of six distinct aspects to the approach. 1. Select the Secret Message—Choose a message that you want to secretly encrypt. In the second step, you will convert the message into ASCII values and then apply the ASCII code to the secret message. In the third step, Apply Eq. 1 to Convert the Encrypted Message—In order to carry out encryption, it is necessary to apply a mathematical transformation. The fourth step is to shuffle the matrix once again using encrypted keys. This step involves swapping cell values in the matrix using encrypted keys. To ensure the safety of the information, plain text is transformed into encrypted text. The process of decryption involves reversing this conversion, which results in the acquisition of the message in its original form. Compared to more conventional encryption approaches, the solution that has been recommended offers a higher level of security.
