Blowfish Algorithm by Modify Randomness for S-Boxes using Fuzzy Value and Apply Encryption or Decryption on Image

Maulik P. Chaudhari | Neha Parmar


Abstract: Information Security has been most important issue in data communication. Any loss or threat to information can prove to be big loss to the organization. Encryption technique plays an important role in information security systems. Information security area there are many cryptography algorithm is available and comparison has been made on the basis on these parameters: rounds block size; key size; and encryption / decryption time; CPU process time in the form of throughput and power consumption. These results show that blowfish is better than other algorithm. Blowfish is more secure and fast computing algorithm. But there is some problem in the existing Blowfish algorithm. blowfish weak keys generates bad S-boxes; Since Blowfishs S-boxes are key dependent. There is a chosen plaintext attack against a reduced-round variant of blowfish algorithm that is made easier by the use of weak key. in this report proposed a new approach to increase the robust of blowfish algorithm and solve the weakness of sub key by generate strongest a cryptographic randomness keys and used in blowfishs S- boxes stages. The proposed algorithm the secret key changes frequently by using randomness fuzzy value which are derived by different fuzzy set of condition after modify algorithm apply encryption and decryption on image and also Modified the F function operation to use of Multithreading to improve the Execution time and improve the Security by the new key generation approach.
