“…The "chose key scheme" is the most important process, because here algorithm will choose the key availability and set which key will be selected as the chosen key A * n to be used in the encryption process in (4) or decryption in (6). The designed algorithm can produce several different and balanced key sets {A 1 , A 2 , • • • , A n } as shown earlier in (3).…”

Symmetric cryptography will always produce the same ciphertext if the plaintext and the given key are the same repeatedly. This condition will make it easier for cryptanalysts to perform cryptanalysis. This research introduces a one-to-many cryptography scheme, which can produce different ciphertexts even if the input given is the same repeatedly. The one-to-many encryption scheme can produce several ciphertexts with differences of up to 50%. The avalanche effect test obtained an average of 52.20%, better than modern cryptography Blowfish by 25.46% and 6% better than advanced encryption standard (AES). One-to-many can produce different n-ciphertexts, which will certainly make it more difficult for cryptanalysts to perform cryptanalysis and require n-times longer to break than other symmetric cryptography.
