Abstract


In the course of the past 30 years, data has become pivotal to all aspects of human life. Data generated, captured, and replicated are increasing in size and expanding applications. The proliferation of fast wireless networks has encouraged data storage within the cloud. So, protecting data from attackers has become urgent to maintain its security and confidentiality, need for security and privacy technologies, systems, and processes to address it.

This research paper proposes a simple and highly secure encryption decryption (SHSED) algorithm that can be used for cloud computing-based applications. It achieves the Shannon’s concept of diffusion and confusion by the involvement of logical operations, such as XORing, addition, and subtraction in addition to byte shifting. It is also characterized by the flexibility in the secret key length and the number of rounds. Experimental results have demonstrated powerful security level and a clear improvement in the encryption execution time measurements and security strength as compared with cryptosystems widely used in cloud computing.
