摘要

Multi-cloud applications including data security are becoming more accepted. This study offers a multi-cloud substructure that guarantees user data security. This structure’s main objective is to keep user data from unpredictable Cloud Service Providers (CSPs). They can be organized with other malicious users and provide them access to user data for their benefit. The data are divided into segments to achieve this and each section is consequently encrypted and uploaded to a separate cloud. As a result, we propose utilizing a novel encryption algorithm. Two-Fish 256-integrative symmetric key cryptography (Twofish256-SKC) is utilized to encrypt user data. The encryption and decryption of a message using a key created using SHA-256 enables the hybrid technique safer. AES and Two-fish are combined to create novel algorithms, which denote hybrid cryptography. In comparison, the hybrid method is simpler to use and more secure. The results of our experiments show that, when compared to the standard encryption algorithm, our suggested encryption algorithm is more effective at ensuring multi-cloud information security.
