A Survey on Hybrid Secure Key Management System (HSKMS) for Multi-Tenant Cloud Environments
Year: 2025
Type: article
Abstract: In a multi-tenant cloud environment, cleanliness could be ensured by securely accessing and effectively keying information using different available ways and techniques. Because of existing challenges such as the security of sensitive data and key management in multi-tenant cloud environments, many traditional key management techniques face contention issues like inadequate scalability, single points of failures, and cyber threats. In this paper, we discuss this problem by diving into existing key management techniques available to secure sensitive data and present a robust, scalable, and privacy-preserving key management system for multi-tenant cloud environments. We especially engineered our approach in a way that an efficient key management system maintains the regular functionality by using the enhanced security by cryptographic techniques, ultimately enhancing operational efficiency to some further extent. The overall proposed system consists of a large number of combinations for encryption schemes, access control mechanisms, and cryptographic protocols to address key leakage and unauthorized access control risks. In also evaluating a broader view of encryption schemes, we provide a comparison between symmetric and asymmetric encryption in front of cloud-based key management systems. Finally, system evaluation is achieved by comparing its effectiveness with that of other existing key management schemes. Specifying certain results could show that our approach improves the levels of security, scalability, and industry compliance for sensitive data protection, putting that into the realm of possibilities for extensive allowance of secure multi-tenant cloud environments.
