Using a modified approach of blowfish algorithm for data security in cloud computing

Abstract

Cloud computing brought remarkable potential changes and excellent opportunities to the information technology industry. It is particularly useful in most of the networked transactions. Cloud computing common issue problems associated with data security. Information is secure if it fulfills the three conditions namely Confidentiality, Integrity and Availability. In cloud computing confidentiality is obtained by cryptography. Symmetric algorithms notably Blowfish algorithm displayed undeniable success in cryptography. In this paper, a Modified Approach of Blowfish Algorithm using Shuffle Algorithm was applied and test the encryption, decryption speed, and throughput. The result shows that the higher the performance, the higher the efficiency of encrypting files.
