A number of technologies are gaining prominence in the current world, and one of such technologies is the Block Chain. The technology in issue provides an incredibly high degree of security; it is quite resilient. Users are not privy to a great deal of information about Block Chain; nonetheless, the functionality of its security is used to protect the data that is sent in several directions. This particular user proceeded to make use of the “Salsa” and RBJ25 algorithms, both of which are regarded as being compact and secure variations. Within the scope of this paper, we will introduce the new security mechanism that we have chosen to refer to as RPBB24-3. Encryption and decryption are the two components that comprise the RPBB-24-3 method. Both of these components are essential to the process. In order to complete the encryption process, there are five processes needed. In this process, the first step is to use the column functions on GT. The second step in the process is to use the “lattin letter” and multiply the value by four using Equation (1). The third step uses encrypted data to swap the cell values, but the process starts with the 0th cell value from the most recent cell value. In the fourth step, the prime key is split into the values of the matrix cells. The fifth step in the process is to use the “SalSa” method in the grid. Last but not least, the plain text is changed into secret text. The decryption process works the other way around from the encryption process. The suggested method is safer than the standard way that is being used. © 2024 Elsevier B.V., All rights reserved.
