Data Management Approach for Multiple Clouds Using Secret Sharing Scheme
Atsushi Kanai, Naoya Kikuchi, Shigeaki Tanimoto, Hiroyuki Satō · 2014
It is widely recognized that clouds have advantages in initial installation cost and availability. However, with the popularity of public cloud services, the concern of confidentiality is recognized as the largest problem. We propose a secret distribution data management approach for multiple clouds to maintain confidentiality that involves a secret sharing scheme. With our proposed approach, secret information is encrypted, and both the encrypted data and key information are distributed using a secret sharing scheme and shared among multiple clouds and clients. Our approach resists eavesdropping, falsification or collusion of cloud service providers.
