A Hybrid Key Management System Based on ECC and Data Classification to Secure Data in the Cloud

Cloud computing is an unparalleled innovation in the field of computer science. However, the CSPs cannot be entrusted with secret data. Data needs to be encrypted before it is uploaded to the cloud. But again, the data is only as secure as the keys used to encrypt or decrypt it. This gives rise to yet another problem, i.e., key management. This paper systematically reviews the literature, identifies the issues prevalent in key management, and presents their corresponding solutions. Post the literature review, we propose a model that borrows the best from the past efforts and fixes the shortcomings of the present models by combining all the solutions presented in this paper.
