Superiority of Blowfish Algorithm

Superiority of Blowfish Algorithm Pratap Chnadra Mandal Asst. Prof, Dept of Computer Application B.P.Poddar Institute of Management & technology, West Bengal, India Abstract: Information Security has been very important issue in data communication. Any loss or threat to information can prove to be great loss to the organization. Encryption technique plays a main role in information security systems. This paper provides a fair comparison between four most common and used symmetric key algorithms: DES, 3DES, AES and Blowfish. A comparison has been made on the basis of 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.
