The security of ChaCha family design from Salsa. The ChaCha design also quarter round process like Salsa. ChaCha20 versions are ChaCha 20/20, ChaCha20/12, ChaCha20/8, ChaCha20/7, ChaChca20/4 are analogue modificaLtions of the 20-round cipher, 12-round cipher, 8-round cipher, 7-round cipher, and 4-round cipher. These versions are compared with itself, and best encryption speed is ChaCha20/4. This ChaCha20/4 main drawback is con-centrate only encryption speed and little bit data security. To overcome this drawback and proposed novel security algorithm is RB22. RB22 algorithm has 3 processes. In 1st process is column operations; 2nd process is multiplication of secret key; and 3rd process is swap the perfect number. Finally, the RB22 algorithm has compared with ChaCha algorithm. © 2021 Elsevier B.V., All rights reserved.
