Abstract—Cloud computing storage services may allow users to simply preserve and manage a huge amount of data at a minimal cost. However, it cannot ensure data integrity. Data is sent to remote cloud servers which might be unsecure and untrustworthy because unauthorized users or the service provider may inadvertently modify data, as a result, data may be lost or altered. Therefore, protecting data from hackers has become crucial to maintaining its integrity. To improve data integrity in cloud computing, this study presents an Implementation of Enhanced Data Integrity algorithm. The proposed algorithm is created by integrating Moving Target Defense (MTD) and New Lightweight Cryptographic Algorithm (NLCA). MTD is used by the EDIE algorithm to dynamically modify network configurations and regularly mislead attackers, reducing the number of attacks and improving data integrity. NLCA provides secure encryption and decryption of data with a faster execution time. In comparison to EDSA and SAKAS data integrity techniques, the results demonstrate that EDIE consumes 6% less energy, encounters only 0.2 percent of all launched man-in-the-middle assaults, and reduces server computing time by 21%.
