Enhancing Cloud Security in Oracle Cloud Infrastructure: Mitigating Threats with Hybrid Encryption
Keywords:
Cloud Computing, Oracle Cloud Infrastructure, Security Challenges, Data Privacy, Access Control, Identity Management, RSA, Blowfish.Abstract
Cloud computing has become an essential part of modern IT infrastructure, providing scalable and flexible solutions for organizations. Security concerns remain a significant barrier to its widespread adoption. This study explores key security challenges in Oracle Cloud Infrastructure (OCI), including data breaches, unauthorized access, identity management, and network vulnerabilities. While Oracle’s security tools, such as Oracle Cloud Guard and Data Safe, help mitigate these risks, evolving cyber threats demand continuous adaptation. The shared responsibility model further necessitates proactive security measures and regulatory compliance. To enhance cloud security, this study investigates the performance of hybrid encryption techniques, comparing RSA, Blowfish, based key management in OCI. Results show that the RSA + Blowfish model significantly improves encryption speed, reduces decryption latency, and enhances security metrics. Performance evaluation metrics confirm its robustness, with accuracy (99.47%), precision (99.12%), recall (99.08%), and F1-score (99.10%). These findings establish hybrid encryption as a promising approach for securing cloud-based data.
