Developing an Innovative Loss Recovery Paradigm for Enhancing Cloud Security in Financial Applications

Cloud computing is taking the lead in meeting where the needs of businesses of all kinds for their computer infrastructure. Data outsourcing reduces management and financial storage costs, the users are not aware of their data is located. Uncontrollable cloud financial data necessitates the need to address new security concerns. The transmission and use of independent processes and systems to enhance financial services have been transformed by financial technology. By using two different keys for safe communication, the powerful cryptographic method achieves message secrecy through encryption and decryption. In this study, research proposed Rivest-Shamir-Adleman (RSA) and Discrete Horse Herd Optimisation (DHHO) for optimal key selection to secure the financial data. DHHO approaches the process of choosing cryptographic keys as a discrete optimization to maximize key selection. In the event that a cloud fails, due to an unexpected incident, a hacking attempt, data loss, or corruption, the improved semi-greedy approach (ISGA) retrieves lost data and restores the cloud backup. RSA+DHHO increased the safety in the financial sector adopted the cloud computing paradigm and established standards for privacy and security in the cloud.
