Securing Databases in Multi-Tenant Cloud Environments: A Hybrid Encryption Approach

Abstract

The proliferation of cloud computing has led to widespread adoption of multi-tenant environments where multiple customers share the same infrastructure, platform, and applications. This shared model poses significant security challenges, particularly in database management where sensitive information from different tenants must be protected from unauthorized access. This paper presents a hybrid encryption approach for securing databases in multi-tenant cloud environments. The proposed method combines symmetric and asymmetric encryption techniques to enhance data confidentiality and integrity, while addressing the performance and scalability concerns inherent in cloud-based systems.
