Symmetric cryptography

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 mod-
ern 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.
