Cloud file access is the most widely used peer-to-peer (P2P) application, in which users share their data and other users can access it via P2P networks. The need for security in the cloud system grows day by day, as organizations collect a massive amount of users' confidential information. Both the outsourced data and the unprotected user's sensitive data need to be protected under the cloud security claims since the advanced P2P networks are prone to damage. The recurring security breach in the cloud necessitates the establishment of an advanced legal data protection strategy. Various researchers have attempted to develop privacy-preserving cloud computing systems employing Artificial Intelligence (AI) techniques, however, they have not been successful in achieving optimal privacy. AI approaches implemented in the cloud assist applications in efficient data management by analyzing, updating, classifying, and providing users with real-time decision-making support. AI approaches can also detect fraudulent activity by analyzing deviations in normal data patterns entering the system. To handle the security concerns in the cloud, this paper presents a novel cybersecurity architecture using the Chaotic chemotaxis and Gaussian mutation-based Bacterial Foraging Optimization with a genetic crossover operation (CGBFO-GC) algorithm. The CGBF0-GC algorithm cleanses and restores the data using a multiobjective optimal key generation mechanism based on the following constraints: data preservation, modification, and hiding ratio. The simulation results show that the proposed methodology outperforms existing methods in terms of convergence, key sensitivity analysis, and resistance to known and chosen-plaintext attacks.
