Abstract :
Every time a sender and receiver communicate,
se-curity has always been a major concern. Numerous
cryptographic techniques, such as AES (Advanced
Encryption Standard), Data Encryption Standard (DES),
Triple DES (3DES), Blowfish, etc., are employed to prevent
security breaches. We make an effort to change the current
Blowfish method based on various factors, including time,
the avalanche effect, and non linearity.
By combining the XOR and addition operations
employed in the original approach, the ”f” function is
adjusted. Sbox is also changed. Text, image, audio, and
video files are encrypted and decrypted using the modified
blowfish method, which is then tested. We generate and
examine nine cases. The findings of all the tests performed
on these cases point to the conclusion that the modified
Blowfish method is more compact and safe than the earlier
because of the security of the modified algorithm with
various cases.
Keywords :
Modified Blowfish Algorithm, Encryption, Ffunction, Multimedia Encryption.
