Abstract	This paper proposes a new approach called the RAES technique, which results from redesigning the current Rail Fence Cipher (RFC) using two basic phases, first using the Advanced Encryption Standard (AES) technique and then using the potential of the RFC technique to protect confidential messages for more secure information security. There are several conventional cryptographic methods, and because it is possible to crack cipher text, that is why it tries to suggest RAES techniques written in C++ programming to be more secure to protect information from cipher breaking. Mixing RFC ciphers with AES, it appears that the encryption and decryption of the modified RAES require the generation of the plaintext elements which are usually single letters written in a predetermined sequence into a matrix format which is basically a rectangle that has been decided by the transmitter and receiver in advance, and then it is read off according to another predetermined sequence across the matrix to get the cipher text. Through this RAES technique, not only the strength of the AES technique can be applied but also the RFC technique that uses keywords and salt can also be used making this mixed system perform ciphers that are difficult to break by attackers. Moreover, the strength of the RAES algorithm is in terms of faster and more secure execution times than existing substitution and transposition algorithms in addition to the improvement of confusion and diffusion characteristics. Meanwhile, the value of the avalanche effect for the RAES technique recorded also showed that it reached 60%.
