Enhanced Data Integrity Encryption Algorithm for Cloud Computing

Cloud computing storage services allow people to easily maintain and manage large amounts of data at a low cost. However, it cannot guarantee data integrity. Data is transferred to unsafe and untrustworthy remote cloud servers. Meaning that data could be manipulated by unauthorized users or the service provider unintentionally, resulting in data loss or modification. As a result, protecting data from hackers has become crucial in order to maintain its integrity. The Enhanced Data Integrity Encryption (EDIE) technique was proposed in this paper to enhance data integrity in cloud computing. The proposed algorithm is designed by integrating Moving Target Defense (MTD) and New Lightweight Cryptographic Algorithm (NLCA) . The EDIE algorithm used MTD to dynamically change network configurations and frequently confuse attackers, therefore minimizing the level of attacks and leading to enhanced data integrity. Computer simulation results further show that, compared to other traditional data integrity algorithms, EDIE yields an energy consumption of 6%, encounters the lowest level of 0.2% of all initiated man-in-the-middle attacks, and reduces server computing time by 21%.
