SECURE FILE STORAGE ON THE CLOUD USING ASYMMETRIC CRYPTOGRAPHY CASE STUDY: Small and Medium Enterprises in DRC

Abstract

In order to create and evaluate an innovative security framework that uses asymmetric cryptography to improve security in cloud-based file storage systems, this exploratory study uses a mixed-methods approach. The main objective was to create a customized security framework that works well with current cloud infrastructures and addresses security issues without negatively impacting system performance. The creation of the security architecture, its deployment across several cloud storage platforms, and performance testing in actual use cases were among the goals of the research. The process comprised a conceptual design, which was then put into practice, rigorously tested, and included user test scenarios, expert evaluations, and simulated attacks. Important performance indicators were assessed, including access times, the speed at which data is encrypted and decrypted, and the susceptibility to security lapses. According to the findings, integrating asymmetric cryptography greatly increased security by lowering the possibility of unwanted access. Crucially, retrieval times were not significantly impacted by this improvement, indicating that it had no effect on system performance. According to the study's findings, asymmetric cryptography can be a useful way to improve cloud storage security without compromising user experience. It highlights the necessity of regular framework updates to keep up with changing security risks and technical advancements, and it advises cloud service providers to implement such cryptographic procedures. It is also advised that the framework be scalable across many platforms and data volumes to guarantee its applicability and efficacy in the ever-changing world of cloud computing.
