Today people life one of the main part is data in the globe; because without data cannot access anything in the globe. Then automatically data need security in the globe. In default, many data security algorithms are available in the globe. But I take the two previous security methods are Salsa and ChaCha. In this work, it has been discuss the drawbacks of previous methods, and to propose a new method named as the RB27 methodology with the matrix of order N. RB27algorithm has two stages. In the first stage have five processes. 1. Identifying prime numbers; 2. Apply the prime number in quadratic equations; 3. Merge all numbers; 4. Form a pair from left to right side; 5. Swap the cell values using before step. In the second stage have five processes. 1. Identifying the prime number; 2. Find a perfect numbers; 3. Merge all perfect numbers; 4. Form a pairs from left to right side; 5. Swap the cell values using before step. RB27 algorithm has compared with ChaCha algorithm. © 2021 Elsevier B.V., All rights reserved.
