The Advances in the Security of Cloud Services using Customer Master Encryption Keys (CMEK)

Abstract

This research paper examines the role of Customer-Managed Encryption Keys (CMEK) in enhancing security for cloud services. As organizations increasingly migrate their data and operations to the cloud, concerns about data privacy and security have become paramount. CMEK offers a solution by allowing customers to retain control over their encryption keys while leveraging cloud infrastructure. This study explores the architecture, implementation, and implications of CMEK across various cloud service models. It analyzes cryptographic techniques, performance considerations, security challenges, and compliance requirements associated with CMEK. The research also delves into advanced concepts and future directions, including homomorphic encryption and blockchain-based key management. By synthesizing current literature and industry practices, this paper provides a comprehensive overview of CMEK and its potential to revolutionize cloud security.
